22 br and 6mm br ??????

I would like a benchrest rifle that can be used for both target shooting and varmint shooting of squirrels. I would like a caliber than I can see the shot impact with through the scope on the squirrel at 200-300 yards with around a 20x or higher scope. Could you give me suggestions on the best calibers and would I need a muzzle brake? Would a 10.5lb rifle accomplish this or do I need a heavier rifle? I'm considering a 22br but would like to use a 6mm br so I could target shoot at 600-1000 yards on occasion. I have never shot either of these calibers. I shoot 22 lrs currently out to 200 yards but I miss alot.

6BR, 8" twist, YES you need a brake. I'll suggest a Holland QD closed bottom.

10.5lb is marginal. I'd go heavier and it'll still be competition ready for 600yd or 1000yd BR or F-Class etc.

The 10.5 wt limit is a point-blank BR limit.

Neither chambering will be competitive for 100-200yd group or score BR.

There are a bunch of guys at our club that go to colo. every year and that is what they talk about. Seeing the things explode when shot.
Most of them use a 20BR if memory serves me correctly.
 
thanks for your experience and insight. I'm going to mull this over . I 'm leaning toward going with a 17 hmr CZ and then later having a custom rifle made up.

What Alinwa said above is correct. I shoot a 25 BR in a 12# rifle, with a BR style stock. Shooting 87 Gr Bergers @ 3250fps using a 8.5-25X50 Leupold set on 25 power I can see the bullets @ 300 yards. I have a 25.5" Barrel with a Harral muzzle brake. I shoot pinned position. Often I can pick up the bullet trace or what ever in the scope just before it hits.

I have a similar 222 with a 6.5-20X50 Leupold without a brake. So far I have never seen a bullet in flight with this one but I can see the impact.

I also shoot a 6.5-284 with 140 gr Bergers. 29.5" Barrel with No Brake with a 12-42 NF & about 15#. So far I have not see the bullet impact with this one.
 
Pinned position rather than free recoil.

I put shoulder pressure, about 15# on the butt and press the rifle against the "PIN" just forward of the front rest bag. The rifle stays in position and the scope stays on target when fired.

If the scope does not stay almost fixed on the target you will not see the bullet hit. I am shooting from a fixed concrete or steel table with top quality front and rear rest.

Launched at 3250 fps the bullet get to 300 yards in about 318 ms. About 1/3 of a second. If you are going to see the bullet hit you have to keep the scope and your eyeball on the target.

Being able to see the bullet and the bullet impact as been a goal for me for some time. Only this last year have I been able to see them.

The muzzle blast, even if you do not see it, will blind you for a short time. This prevents seeing the bullets or the bullet impact at closer ranges. So far I have not seen bullets or bullet impacts at less than 300 yards. At longer ranges it is easier. Scope quality, resolution is important.

I love my 22BR and I love to shoot prairie dogs. However, the 22BR barks too much to see the impact. I'm getting a muzzle brake put on it to see if that will tame it down enough.

My favorite prairie dog round is a 20 Tactical. I measured one prairie dog in June at 504 yards with a 20 Tac barreled AR. The plane ole 223 is also a huge favorite and I think everyone should have at least one.

I've read all kinds of stuff about how the .17 HMR is this great prairie dog rifle out to 200 yards, and I'm sure it can kill them out that far. The problem is when the wind is blowing, which of course it never does on the prairie :rolleyes:, to try to hit them.

With marginal hits which are always possible, I doubt that any rimfire is going to be effective much past 100 yards, maybe not that far. The smallest cartridge I use is a .222 Rem, and although it's effective and works well out to 200 yards and beyond it's not quite up to the .223 or .22 BR. Except for the .222 (CZ 527) all my live varmint rifles have heavy barrels so that I can see impact over 90% of the time even with my .22 BR (#8 Hart truck axle, er, I mean barrel). The 6mm cartridges cost more to shoot and are really overkill on prairie dogs IMHO. They do the job, but it's like using a .375 Mag on whitetails.

My scopes are no more than 20X, so if a guy uses a higher powered scope with more limited field of view seeing impacts is harder.

A combination rifle for match shooting and live varmint shooting is always going to be a compromise. It will either not be a competitive match rifle or it will be a pain in the field.
