308 with 1 in 10 twist

[bulldog284]

hello

i just bought a savage model 10 with a mcmillan stock in 308 with 1 in 10 twist.i would like to do some experimenting with the 210 bergers and the 208 amax.
wondering what powder to use, it will be for longrange 600 plus.i have used the 185 with good results in fclass competition.

by the way this rifle is not my competition rifle just bought it because of the 1 in 10 twist to see what i could get out of it with the 210 before i make a decision wether or not to order a 1 in 10 twist barrel.

all thoughts and experiences are well come thanks Darin

bulldog,
i shoot the 185/190 projectile from a M1 Garand in .308. i use 44.2 grains of IMR 4320 and jam them .007 in the lands. with a bolt gun you should be able to get a little more A@# behind it. i think i would also do the same load with the 208/210 projo. Just don't try and hyper drive the amaxs or you may make them puff before they hit the target. i think the thin jacket on the amaxs don't tolerate light speed well. i hope this was helpful.
cheers and good luck,
doc

I shoot 42gr or 4895 under a 210gr Berger seated .005" into the lands , with Lapua brass and FGMM primers it gets the long Berger to 2370+fps from a 18" barrel with plenty muzzle flash but it shoot well to 1000yds.

Personaly i think you are much better served with a 168 Berger or 175gr Berger in the 308
I shoot 47gr N550 under a 175gr Berger as my long range target load , very accurate and shoot flat for the 308 , vel in just at 2700fps froman 18" barrel , I think that about 2-3r over spec but it shoots fine in my gun which is chambered with a Palma 95 reamer so the bullet are not seated out that far to get into the lands

Reloder 17 is a popular powder for the heavies in .308 Win, you'll get some good velocity with it.

rl 17 was the poweder i was thinking of as well for the 210s or varget,i have some vivo.n150 on hand dont know if that will do?what are some of the loads you would recemend for rl 17? Darin

FWIW, I have a Surgeon actioned 308 rifle with a 1-10" Krieger @ 24" and with 43.5 Varget, Hornady Match Brass, Russian primers, and the 185 Scenar shoots extremely well. I do load them for the box mag so I have to worry about OAL, but the proof is on the target. My barrel is not picky about the bullet weight and SMK's or Scenars all shoot good. That being said, the Amaxes in 168 and 178, not so good.....

I have not used any Re17 or any of the 208-210's.

 

[bulldog284]

it would seem that not to many people us the 208 or the 210 bullets in a 308,they seem to stay with 155,168,175 or 185 :-\ :-\

 

[uncleduke]

Just my 2 cents but the 200smk with 44.5-44.8 of IMR 4007 will put you at 2550fps with no over due pressure and works well out to 1,000 yds. My first F/TR rifle was throated for 208amax and w/N550 I just couldn't find a load to hold vertical. Berger 185 BT Match if you can get them would be a good choice. The RL-17 loads I tried w/200smk's gave more velocity but didn't work on paper for vertical. I use lapua brass, CCI Br2, in a Warner '95 Palma chamber.

Bulldog284,
If you are Planning on shooting F class out to 1000yrds. The 155s might be oaky for 600, and they will do good at 1000yrd, but the 185gr. Long Range BT Berger (not the VLDs) will give you better performace at 1000yrd than the 155s. If you want to try the 210s, and I'm just talking out load here. I have no experience with the 210s, but my first thoughts would be that from your 24" barrel you may not get the 210s to shoot with enough vol. for 1000yrds. I would also think that RL 17 would be the best for the 210s with a shorter barrel, but again as others have said here, as well I have talked to several other ppl that seem to have problems with vertical in the 308 and RL 17 (210s).

I haven't shot any 185s in comp. yet. I have worked with them a little and have ran out of bullets while doing load development with them, and they are out of stock everywhere! I could probably email a guy that may have some, but not the amount I want to order. When I order them, I want to buy at least 1000 if not 2000. I want everything in the same lot!

Currently I'm shooting the 175gr Berger LR BTs with 44.2gr of Varget, CCI BR2, Lapua Brass, bullet jammed .010, at 2750fps. My 308 is the 10fcp with the HS stock. I can say that the rifle will shoot, and shoot well. As far as competeing against other shooters that are shooting on a national level! I most likely don't have a chance to beat them. As well When it comes to F class its hard to beat the 284 wins and 284 shehanes, with the 180gr bergers with a 308! So I am thinking of getting into FTR as far as this rifle is concern. Even thought of going to a Custom hand lapped barrel for my Savage, but I only have 728 rnds down the factory barrel. So there is plenty of barrel life left in my 308. I don't feel the need to upgrade my barrel at this point. It will be more benefical to me to spend the money on loading components, giving me more time on the range and getting past my Wind, and Mirage reading learning curves. Rather than going to the expense of a new barrel blank, another PT&G reamer, and cost of simth work.

If it was me, with the rifle you have I would go with the 175gr LR BT, or the 185gr LR BT Bergers. Witch every I could find first! If you can't find them don't forget the 175gr SMKs! In My experince the 175gr SMKs will buck the wind good but not quite as good as the Berger's. The SMKs need to be sorted by bearing surface, more so than the Berger's. As well most likely you'll need to jump the SMKs where you will need to Jam the Berger's in a factory chamber. Mostly due to your throat length in the factory chamber, and the difference in ogive design between the 2 different bullet manufactures.

Ps. I would also go with Varget, and start somewhere around 40.5gr bullet touching the lands, and work up. Both in powder charger and seating depth for the berger's, Same charge for the SMks, but work back from the lands. Also Only change one thing at a time! (powder charge, or seating depth!!!)

RELOADER 17 I know for a fact it works with the 208's the 210's and I have even seen it used behind some 220smk's with honest good results. I have seen the 208's in three other guns besides mine and the Reloader 17 works.

coyotehunter

do you want to share any of your reloading info with me??i am quite formilliar with fclass shooting i have been competing for the last 3 years and this year i finished quite well in the canadian national.i was using the 185 bergers with varget with good success.but i want to see if their is an advantige with the 210s.on paper their seem to be but in the real world is sometimes different.i have heard that another powder to us for the 210s is v550?what type of velocity could i expect with the 210s out of a 30 inch tube with rl17 and v550?

bulldog,
I don't know if you have been over on sniper's hide or not? There is a group of guys that hang out on that site, and they have worked with the 210 bergers, 208 amax's, and RL-17 in the 308. Not sure how many of them shoot F class or FTR but some of them shoot some comp. At the least they will be able to give you a starting point with the 210s or 208s and RL-17. Plus some velocity expectation. If you get lucky maybe (Laurie) will see this thread and chime in on the VV550. He as well has had alot of experenice with the vv powders. I consider him a good source for info when it comes to the 308, and different powders that works best for them. Good luck!

Just went to the range yesterday and tried 210 Bergers with RL17 in my 28" 10 twist Obermeyer Model 70. I was not impressed with repeatability in any of the loads I tried. I wasn't pushing it very hard, either, so that may be an avenue for further exploration. Recoil was less than with 168's AMax's at 2600 fps out of my 12 twist 24" Kreiger.

Neither were as repeatable as 155 or 187 BIB's with Varget. I did get good results with 187's and RL17, but was loading them so stout that they were painful to shoot, and the torque wanted to twist my rifle out of the front rest. N140 wasn't bad with 187's.

And, keep the 210's off the lands unless the action has been squared...

 

[bulldog284]

hello

i will be going to the range tomorrow if everything goes as planned.reloaded 3 different loads 45g 45.5g and 46g of rl17 with the 208 amax just touching the lands.will be using winchester cases for testing.

also reloaded some 180 jlk with 44.5g and 45.0g of varget all testing will be done at 200 yards,see what happens.

Bulldog,
These are some extreme loads work up to them slow and easy. The guy that is shooting the 220's is using 49 grains of reloader seventeen. Its a lot of powder behind a heavy bullet I know. But it is working for him. Its a factory remington 700 varmint 26inch tube. I myself have found that out to 700 yards the 190 smk's print higher than the 208's but past 750 the 208's over come the distance better and start printing higher than the 190's momentum momentum momentum. Im shooting 47.8 grains of reloader 17 behind the 208's. I would start around 44 and go up from there. Just a tip. I have not found the benefits of heavy bullets untill I reach 600 yards or more.

 

[MaxOwner]

Post for interest.

I have a bunch of bullets mentioned above and plan on using Varget for the most part. Have pound of 4350 (I think) that will also be used. and VV aswell.

 

[best defense]

I was wondering if anyone has tried a twist rate for a 308 faster than 1:10 and if so, what was the result?

I was wondering if anyone has tried a twist rate for a 308 faster than 1:10 and if so, what was the result?

With what bullet? I currently am using a 9-twist with [extremely] long monolithic bullets and have an 8-twist on the way. They certainly work when the length of the bullet requires such a fast twist rate in order to stabilize them properly. However, there is definitely more torque on the rifle that will require even more precise gun handling. I wouldn't choose such a fast twist barrel unless the bullet required it. More often than not, I have the best results using the minimum twist rate necessary to achieve an Sg of about 1.5, or even just a tick slower (see Berger's Twist Rate Calculator: http://bergerbullets.com/twist-rate-calculator/). For example, under the conditions I shoot most often, you need about a 10.5-twist to achieve the full BC of Berger's 200.20X bullet (Sg = 1.5 or greater). However, I've been running them out of an 11-twist with excellent results. Anything much slower than 11-twist would probably start to give poorer performance (i.e. loss of effective BC and/or instability issues if the twist was slow enough).

I shoot F-TR with a Kelby .308 , Brux 30" 1-10 twist , and have had some decent success using the Berger 185 Hybrid Target bullet in front of 43.3gr of Varget . Rem BR primer ... 005 of touch in my rifle .
For 1,000 , I go with both the Berger 200.20x and 200 Hybrid . 44.1gr of Varget for both 200 loads . I am chambered with the 2013 FTR reamer , so loading long is not a issue . You may even gain accuracy by slowing the round down , contrary to chasing max velocities . Heavy bullets and .308 1-10 barrels sometimes shoot better that way . I found a low "node" at 2590-2610fps and a high node at 2740-2745 . Go figure that one .

I have yet to try the 200.20X bullets, but my favorite so far in my personal Savage Model 10 are the Berger 185gr Juggernauts.

I plan on trying the 200gr Hybrids and the 200.20X here in the next few months.
