long range varmint gun

[daniel brothers]

that 22/6mm will move... it's about the same as my 22-243 AI, and it will shoot 80 amaxes 3500- 3600.... and 90 bergers up to 3400

 

[fredo]

Prezactly.

Button the chin strap, throttle that big sucker up, and enjoy the ride while it lasts!
IMHO, dudes don't build .22/6mms for longevity, they do it for the horsepower gains & wicked performance. An 80gr @3500 is right in the wheelhouse of what I'd be wanting from a .22/6mm. And there should still be some pedal left, before ya hit the floorboard...

Have fun!

Now that in getting a 6 dasher built, I reall want a 6mmAI also!! And maybe a .22/6mm.

Mines just gonna be a play gun. Probally shoot more steel than anything. Probally load some lighter for coyotes though

 

[Webster]

Thanks, I should have mentioned earlier that I have several thousand 6mm bullets so a 6mm chambering would probably be best. So straight 6mm rem, 6x47, 6-284. 6 dasher? 6xc?

6XC is fast and very accurate. Decent barrel life.

6 years ago, I bet ya it has been rebarreled a time or two since then.........

Kinda my thinking as well.

Hey - how about the 6mm SLR? 105g @ 3050 with slow powders, long neck, 30 deg shoulder and cheaper brass?

The 6mm Super LR — .243 Winchester Made Better « Daily Bulletin

In our Forum recently, there was a discussion about improved cartridges based on the .243 Winchester parent case. One popular such cartridge is the Super LR, a 30° long-necked wildcat.

Look at the Nightforce for your varmint rig scope. I use a NSX 5.5-22X50 with the MOAR reticle and once you have a click chart you can either use the status lines or click for impact.

I have zero and 50 freebore 6br Ackley barrels in stock.

I also have 50 FB 6xc in stock.

I wish i had an answer but i have no clue. I will be buying a chronograph later this week though.

Any gun you shoot a lot and can shoot accurately practice. Practice, practice .

I use a 6BR for daytime varmint hunting.1-8T barrel and 85grn sierra varminters.excellent on crows,rabbits,foxes and deer.i shoot lots of crows on open moorland ground where they are a pest to sheep farmers.100 to 500yds and abit beyond is normal..Great calibre.

Any of you pro varmint shooters got the time, I need some advice. Around my parts the only varmints that are available for shootin are coyotes, crows and wolves. Probably never bother with wolves though. Im looking for a set up as in caliber and scope for long range say out to 6 or 7 hundred yards. I have a 6br 8 twist but shes a bench gun only (to heavy), and my current varmint getter is a cooper model 22 in 22 250 shootin 50 grain vmax. Its a 14 twist so cant shoot any heavy's. The crows here only show up in the spring and stay until fall and they are very smart little buggers so I need something that will reach out there. I am happy with the cooper and want to re barrel it to an 8 twist for the heavys so my question is what should I re barrel it too? 8 twist 6BR? 8 twist 22 250? .243? I already have all the 6br and 22 250 dies so it would be best to stick to one of them. Also im wanting to be able to make a click chart so I can hopefully range the target and click for windage and elevation. Would a huskamaw system be any good? Or any recommendations on a good long range varmint scope?

I have a 6BRX just load and shoot to FF. Same ballistics as a Dasher. Small groups when FF. A lot of the calibers mentioned are barrel burners. Do you want to spend $700 every couple years for a new quality barrel. My 6BR Kreiger barrel has about 4000 shots on it and still under .400" groups with 68 gr bullets. Never tried to shoot over 350 yards. It would be interesting to compare wind drift a 500 yrds for a 68 gr bullet at 3500 fps compared to a 105 gr at maybe 3150 fps.

Mean while back at the ranch………lol, this is the thread that pushed me into a 224 Clark, aka 22-6mm AI, last fall. Original Clark stamped barrel, dies and Clark bullets. It turned into a project as the action had issues, bubba had a drill, twice and he ground the rear bridge down, so we swapped actions and then had to restock it as well, don’t ask. Best thing was it headspaced well on the new action.

I ran that scenario in StrelokPro with a 10 mph wind. At 500 yards the 105 shows 2.7 moa of drift and the 68 shows 5.1 moa of drift. That’s 13” more drift for the 68 grain bullet.

I believe the parent cartridge is the 7 MM Mauser ?

I Have been shooting a Dasher with Varget and 105 Amax with awesome long range accuracy for varmints. Unfortunately I only have 1000 left. Very happy I chose the Dasher so Far.

Depends on how far...is far. Used to belong to the Varmint Hunters Club...I use a 308 Win for the first one past 1000 yds. But 308 Win was used for a 2200 yard PD shot, 220 gr SMK. Then it began to get outrageous there 338 /416, 338 Lapua Mag, 3200 yd kill recorded..before the end of the Club.
Dan Lilja was messing with the 50BMG, plus a bunch of others, even more outrageous16 sec bullet flight times and s forward observor. ..so I got a 50BMG for a squirrel gun too...but haven't used it for that..yet.
Today for 1000 yds probably use my 6 dasher, next would be my trusty 30" 8 twist 308 win heavy bullets 200 gr to 230 gr to spot the impact. Little bullets are much harder to spot, and bigger diameter will kill rodents without mushrooming...as they all become FMJs at long distance. And you can easily be your own spotter if the distance to the target is long enough. Time to get back on target...a 308 is easy past 800 yds prone, hard hold. Lower power scope, with good eyesight and a 2oz Jewel trigger...shoot fast when your on, throw lead, bullet gone in 5 seconds...a few hits pop cans or squirrels..instantly, the wind changes, you're way off target. Practice with purpose every week sometimes more with 85 to 100 rds. Of the same exact proven low S/D load, do not change and chase the latest thing in powder or bullets...this is your rifle this is your load. Practice winter, light snow, rain, summer heat...learn your hunting/ shooting area..land marks, wind currents, how it flows through the canyons... after a certain amount of time and a few thousand rds, you own the area, acquire targets quickly, and if you can see it you can hit it, mindset,...and 800 yds becomes close range.

There are a couple of cases you can use. I have seen some variation on reamers, much like many wildcats. This particular barrel has the original markings on it, as do the numerous boxes of original bullets, all crude by today’s standards. Bullets just look terrible.

Two years ago I tried this 6mm fast twist idea to stabilize 103 to 108 bullets. Results were very dissapointing!

If you want to shoot these bullets and obtain the accuracy needed to be efficient on long range varmint size targets out 600 to 1000 yards the 1-8 twist or faster is needed.

The problem is when you get any bullet turning the rpms beyond 3000 to 3100 fps, your doomed! No bullet will take more "rpm's", without showing the stress on the target beyond 300 yards.

My choice was a 6mm Rem. AI. My results were fantastic with three different powders, until I pushed beyond 3050 fps. The faster I ran them, over 3300 fps they just got worse. Randy Robbinet warned me, and really didn't want to sell me his 104 for this project. He let me know his concerne was not the speed. But the rpms required to stabilize them.

He was right! I used bullets from as good as it gets, 104 and 106 hammers, Berger 108 EH and 105 Hybryds, all gave superb accuracy under .3 moa, till I pushed beyond 3000 to 3100 fps, beyond that they just got worse as the speed increased.

My sugestion, 1-10 twist and 80 to 95 grain bullets. At 3600 fps they are still turning less rpms than the 1-8 twist dose at 3100 fps.

I had the 27.5" 6 AI barrel recut, 26" and chambered to 6x47L, those bullets are running 3000 to 3150 and with much less powder doing the same thing they did in the AI, but make no mistake, they only work in their happy place.

Beyond 600 yards they will not open up, the just poke a tiny whole, an if your like me, and you have to kick em to count em, your going to loose a lot that make it back to the den, you simply can't count them, if you can't kick em!

My new project, is the 6mm AI with a 1-10 and 80-95 grain, since I have 100 of the finest pieces of brass ever made for the 6mm Rem AI, 8x57 Lapua turned and formed that have already proven to be tougher and as consistent as any 6ppc brass I ever cut. My 6x47L brass is good, but not as tough as the 8x57 I painstakenly made for this cartridge.

I am really debating a 1-10 twist .257" barrel, for a 257 Robert's AI, with 85 to 100 grain BT's, in my opinion the best long range varmint rig I ever sqeezed the trigger on! Corn cob media over 14 grains of bullseye capped with bar soap, and brass is ready after firing it in the 257 AI chamber.

In my humble opinion, this is as round as the long range varmint wheel get's!

But make no mistake, when a bullet reaches a speed it will no longer open up on a thin skinned target, is less affective than a hit from 45-100 shsrps, and dam sure not what I would consider a long range hunting weapon, for any live animal including but limited to varmint!
