Project: 243 hunting/longrange rifle. Update march: HUNTING

This post might not quite fit the 6mmbr site profile, but I take it there are some hunters here as well as target shooters so will post. My first post seemed to be received well enough, so put some effort into the second one as well. Moderators can always remove if so desired...

I'm presently building a hunting rifle fully capable of longrange target shooting. The goal of this project was

Lightweight
Inexpensive


So picked up a secondhand Sako Forester in 243 quite cheap, smacked on a aluminum picatinny rail and Hitech stock. Weight is about 3.5 kgs (7lbs) with scope and moderator, it groups rougly 15cm@600m or 6"@660yds and have so far cost the same as a standard Rem700.

Finished the rifle with Duracoat. If the surface is prepared properly you'll have a very durable finish.

Used orange for safety features. Will remove orange from scopemount.
Blog_A_%286%29.JPG


Chose 10 MOA (actually it's 12 MOA) angle to get most out of my hunting scopes and enough out of my LR scopes...
Blog_A_%284%29.JPG


Very easy to see when this rifle is cocked...

The trigger and safety was flagged with green more as a practical joke on my behalf :D

Again the orange details...

Have used it in the field already. Seen lots of deer so far, but was too busy filming to shoot them and the fallow is not legal with the present chambering which is 243.

First kill was a fox. Absolutely in love with my moderator - reduces recoil to nothing and game close by isn't spooked.

There's a short video of the build here:
VIDEOBLOG HERE

Look for english titles to get the texted versions...
...
Looked over the rifle tonight, it's still ok with Duracote (I only clean the barrel these days) but it is slipping where I didn't do proper surface preparation. This was expected.

Put the rifle on the scales, have failed slightly in my 3,5kg statement but can't really see how I could have built it much different either. Wasn't willing to use a very short or pencil thuin barrel. Would've had to pick up a slimmer Kimber for less weight I think.

It's almost a system rifle (not a true system rifle, but poor mans version) and depending on the configuration/barrel it weighs:

Assassin 4,352 kg. This is the use-all-opportunities configuration with a 4-16x50 PMII and moderator.
Stalker 3,919 kg. As seen in the hunting blog. This is mostly for recreational hunting with a Zeiss 2,5-10x42 and moderator.
Alpine 3,469 kg. Only configuration that makes the weight limit; with Swaro 3-9x36.

System components weigh:
Rifle 3,005 kg
PMII 1,066 kg
Zeiss 0,633 kg
Swaro 0,464 kg
Moderator 0,28 kg
The Sako Forester action weighs 1,050 kg.
...

Velocity with the 243 and Hornady 87gr Vmax is 950 m/sec with a 18,5" barrel.

normal_dz.jpg


normal_dz_%281%29.jpg


The barrel is only 18,5" long. Didn't really pay attention as we were building it.
Short barrel shooting an inferior Bc 0,4 bullet but still first-shot hits at the 0.2-0.4 MIL sized targets I've shot out to ranges of 750 meters (825 plus yards).

Here is a video of me verifying the trajectory calculations

All in all I value my hearing a lot more than the marginal increase in killing window a longer barrel will give me, so next barrel will be at similar lenght.

Put out a new video
Blog entry 9, rifle details

Not really anything new there, just beaming about how pleased I am with this rifle so far :D


...

Visited the workshop again. He worked and I filmed. I like! ;)
normal_1.jpg


The original plan was to put in a 6,5x47 barrel in the project rifle now, but all my Sako's received good offers and were sold as we were working. It'll now be a 308 and my 280 will be a 6,5x284 and the new owners will have the rifles in May. Bought a Blaser R93 Pro stock with an unusually good trigger yesterday and also got hold of a secondhand 6,5x55 barrel. Ordering a bolt soon.

Anyway, mounted picatinny rails on all three Sakos. Used aluminium as this is more than strong enough and weighs a lot less than steel. The scope will break before the rails so no worries. Put in 20 MOA cant this time.
normal_2.jpg


This is the rail on a Sako Finnbear action. Chose the picatinny system as it provides a rock solid mounting solution.
normal_3.jpg


A small surprise for me. The short-action Sako Forester action weighs 1082gr/ 2.385 lbs complete and the long-action Finnbear weighs 1156gr/ 2.549 lbs. A tiny difference only.
normal_4.jpg


normal_5.jpg


Used Duracoate quite a bit this weekend. Use a mask, was sick for two days after. Subdued the rifle a bit in colour and added some details. The safety now shows only green when safe, and red when unsafe.
normal_6.jpg


I liked this green. Create it by using WWII Olive Green and add same amount of white as hardener.
normal_6a.JPG


Used a 1000W lamp for drying this time. After 30min it was dry enough to accept masking tape without marring the finish.
normal_7.jpg


Will not say to much about this as it isn't finished, but the end result will be fool-proof turrets that can easily be marked/remarked. Note how I put the spin drift on the windage turret and also put some yellow (yellow/weak/left) on the scope ring. As said project not finished, it will look slightly different but should be good and user friendly.

This is it for now. Hope this can inspire shooters wanting an accurate rifle without putting out too much cash.
 
Re: Project: 243 hunting rifle capable of longrange

Great post! Maybe I missed it but where are you located?
 
Re: Project: 243 hunting rifle capable of longrange

Not sure I disclosed that information, but it's Norway. I do my shooting and hunting as seen in the videos all over Norway/Sweden/Scotland.
 
Re: Project: 243 hunting rifle capable of longrange

That is a pretty cool build. I like the idea of the orange to tell when your rifle is cocked really fast visual check.
 
Re: Project: 243 hunting rifle capable of longrange

Nice work Roe!
That Forester looks very much like my L57. Great actions.
The 6.5x47 Lapua would have been a good choice.

Thane
 
Re: Project: 243 hunting rifle capable of longrange

Roe, thanks for sharing that! I only made it to Norway once, and really liked the place. Excellent hunting and fishing opportunities there... Great people and good beer too!

You've got a nice hunting rifle...
 
Re: Project: 243 hunting rifle capable of longrange

MORE than SLIGHTLY impressed, I learned a lot from this superior post. Bullet configuration and powder charge and powder type are EQUALLY important, so please give us some downrange specifications for down-to-earth application. Cliffy
 
Re: Project: 243 hunting rifle capable of longrange

Cool Buddy, but you may note that a 90 grain Swift Scirocco II bullet powered by a proper charge of H4350 powder is tough to top in most 24" barreled rifle applications, when dealing with the extremely deadly-force of .243 Winchester fare. Please give us your results, and I'll reciprocate regarding my Remington "Stock" except for trigger modified Model 700 action afield. Born to learn, but eager to impose my multi-thousand round findings to date. Perhaps we can complement said findings into a fiery combo of pure downrange destruction. Cliffy
 
Re: Project: 243 hunting rifle capable of longrange

My load is 87 Hornady Vmax in front of XX grains of Vit N160 in Lapua 243 brass. It exits at 950 msec in my 18,5" barrel and kills deer very reliably when shot in the shoulders. In the lungs it produces a bit of soup. Tried Federal Fusion 95gr factory as well. Very accurate and knocked them dead also. So far only shot 17 deer and a dozen foxes/hares with this rifle.

This is what the present project all started with: My old Tiny-Sako in 6x45 with a good buck on a perfect day... Shot some 25-30 deer with this rifle using the Sierra 85gr Gameking exiting at 830 msec but wasn't too happy about the lack of effect when shot in the lungs.
A_Vmax_%285%29.jpg


So this year I returned with another 6mm, my Sako Forester in 243 configured to be a proper tool for killing...
B_svenskemetoden_%281%29.jpg


Before departing I used the Swedish Method and calculated a trajectory on a predicted atmosphere. I came very close and the predicted trajectory fit on the click out to the 750 meters I tested it.

The rifle is in original factory state and is just wicked accurate so it was with good spirits I awaited first dawn...

Here are some pictures showing the effect of Vmax on these deer. I've put the explicit pictures behind links as not to offend...

Hope this embroids a little more on the 243/ 87gr Vmax combo I use.
It's good for killing deer, but have sold this rifle with a 308 barrel now and bought a Blaser R93 pro in 6,5x55. Same weight/size package and quite a bit more potent at the longer ranges as well as being way cheaper to shoot here in Norway.

Re: Project: 243 hunting rifle capable of longrange

Wish I had 2% of your computer skills, Roe. I can't even post a picture, but one picture could replace a hundred of my words and maybe more. I've promoted the power of a .243 Winchester, in words, for some time and some people tire of my retoric regarding same. Are you plagued by Feral Hogs in Norway? Cliffy
 
Re: Project: 243 hunting rifle capable of longrange

Thanks for that Cliff.
No we don't have feral hogs at all in Norway. No varmint in any numbers to genererate varmint hunting like you have in the US. The closest we get is some dedicated fox hunters.

As the fitting of picatinny rails to the Sako has generated more than a few questions I've made a video on the subject as well.

It's quite easy for a machinist to do this, just order a blank picatinny rail from Brownells ($26) or something. Then it's just a matter of shaving some metal and drilling a few holes. The video shows this in much greater detail than the earlier blog. Hope this answer some questions.

I concur with cliffy that the 90gn scirocco would be hard to beat in the .243. Unfortunate that my 10 twist tikka barrel doesn't like them. I had an 87gn Hornady Vmax explode on the shoulder of a boar when spotlighting one night and I will never use them again. I now use the 90gn speer hotcor and I have been very pleased with the terminal effects so far.
 
Re: Project: 243 hunting rifle capable of longrange

Moo Buddy, I've had superior ballistic performance and accuracy using Speer Hot-Cor 100 grain Grand Slam bullets. With a muzzle velocity of 3050-3100 fps, I don't find these missles lacking in energy or striking force. Cliffy
 
Re: Project: 243 hunting rifle capable of longrange

Thomas,

Absolutely awesome report and great photos.

These days, when I see images that good, I think "Canon?". Sure enough your photo tags say Canon G9. I use the G10. These are both amazing cameras.

Your story needs bigger coverage -- please email me at mailbox@6mmbr.com
 
Re: Project: 243 hunting rifle capable of longrange

Thanks for that, email sent.

Yes, have been using the Canon G9 for years now. On my second camera and it is so scratched and worn it'll die soon. I'll be sad to see it go as my new G11 doesn't have the same definition when filming.

All the video in the blogs is taken with the G9 camera, I still haven't put out anything from the HD video camera. So very pelased with the G9, not quite that pleased with the G11 for my allround use. Will have a proper look for new G9's soon.

I agree--think this oughtta' be one of the articles here. This guy is doing some things!
 
Re: Project: 243 hunting rifle capable of longrange

Hi Roe! 370bc here. I have a question in regards to your shooting sticks in the pic while you were lying prone. What brand are those? Thanks.
 
Re: Project: 243 hunting rifle capable of longrange

Not really sure. Brand name worn away after years of use and only know what store to buy them in. These BogPod sticks seems to be approximately the same product.

Re: Project: 243 hunting rifle capable of longrange

I've got a few questions none of which have to do with the gun or camera. I'm a die hard hunter..What is yalls, deer bag limits. Second that is either small deer or the biggest rabbits I have ever seen. 3rd, do you have your own walk in cooler??
