Barrel selection and muzzle brake

AS I continue planning for my F Class (O) build, I need to decide on what barrel taper (if any), and length, to select. I am handcarving my own stock so anything goes on the barrel. The 700 receiver is 1 3/8" in diameter and the standard barrel shank is 1.25. Since my 30-06 is going to kick like a mule, it would seem that the heavier the better. What do you think of 28" and 1.25 diameter the full length. This would put my total rifle weight at about 14-15pounds, with the Oak stock I am building.

Does a good muzzle brake affect accuracy? Would it reduce the recoil significantly (I know it is supposed to, but is it worth the 300 bucks)? Would you recommend a muzzle brake with the 30-06 shooting 180 grain, or so bullets?

I haven't made the final decision on the caliber, but right now I am leaning toward the tried and true 30-06. I don't expect to win tournaments, I just want to enjoy accurate long range shooting.
 
Where did you learn to measure?

The last Remington 700 I measured was 1.350" not 1.375".

The last Remington tenon I measured was 1.0625" not 1.250".

Now the shoulder may have been 1.250".

Unless things have changed Muzzle Brakes are not allowed in F-Class.

You may or may not make weight class if you use a 28" or longer 1.250" barrel and a "oak" stock.

Good Luck

I'm a bit confused. In these parts no one shoots a 30-06 in F Class. Where might the 30-06 have been tried and true in F Class?

Joel,

The 30/06 probably isn't popular in F-Class anywhere. However we have a 300WSM that's going very nicely in Australia, and ballistically the 30/06 wouldn't be far behind. In fact a 30/06 AI would be extremely close. I did see one of those on the mound a year or so back, but he used to look fairly bedraggled at the end of a days shoot, and last I heard he was back shooting a .308 in F/TR :D.

Nix the brake. If you decide on a .30-06, it won't kick very badly at F-Class weight.

But I would strongly consider a 7mm variant, like the .284.
 
Bill,
I probably will go with the 6.5 or 7mm. But, I guess I never will understand why either is better than the 30 cal. There are more bullet varieties available for 30 cal than any other. The 30-06 has been around for106 years, and sometimes I wonder if other calibers are just a fad. With the huge variety of powders and bullets available, I suspect the 30-06 will do anything the 6.5 or 7mm variations will do. It is kinda like dissing the truing of the Remington 700 action as opposed to spending $1000 on a custom action, I really doubt there is much difference if it is done correctly. The Army still uses the 700 action for their .338 Lapua Magnum sniper rifle, not a Bart. I kinda thing they know what they are doing.
 
don't quote me on this but

I believe the military is looking for 1 or 1.5 moa which equates to approx. 10-15 inches at 1000 yards while we are looking for half moa or 5 inches at 1000 for perfect score with 20 x's unless you are shooting palma with peep sights then you are looking for 1 moa or 10 inches for perfect x count.

Yes guys i know 1 moa is not really 10 inches at 1000 yards, but to keep things simple yada yada yada.

model 14,

In F-Class, you need a high BC and velocity (to reduce wind effects), and reasonable recoil, because you often fire many shots in a day (I fired 83 on Saturday). To get BCs comparable with the 6.5mms and 7mms, a 30 cal needs to go to a much heavier projectile. This means greater recoil (assuming the same velocity). With no muzzle brake and 10Kg (approx 22lb) all up weight, the 7mm recoil is about as much as most shooters are prepared to accept - and some say 6.5mm is the best compromise of ballistics and recoil, although the conditions at the recent World Championships at Bisley showed a clear advantage to the 7mms.

So they aren't just a fad - shooters choose their calibres based on performance, and while the 30 cal is probably the pick for LRBR, it does not have the same appeal in F-Class, for good reasons.

Alan,
Thanks for the very educational response. I believe 260 is probably as good a choice as any for me.
