Little help with caliber choice

[PAshooter20BR]

Looking to build a benchrest rifle for shooting local club matches. Yardage’s are 100,200,300 and 500 yards. I have narrowed my choices to the following - I am not looking for a case that’s needs a lot of forming work. 6BR, 6mm Norma Dasher or 6x47 Lapua. I personally prefer the 6x47 for the velocity gains but hear so much about it being difficult to tune. All cases will running a 105 class bullet. Can you guys help me out?
Thanks in advance.

You will be hard pressed to get easier than a 6br at those distances. Troy

Straight 6br seems to fit your criteria best. I was once hot for a 6x47, but found so much stuff about being difficult to tune that it scared me off.

+1 for the basic 6br. Easy to tune, easy to shoot (very little recoil with a 15-17 # gun), very accurate, components available.

AS SAID 6BR

 

[ttfreestyle]

But on the other hand a 6bra will do the same thing and get ya a lil more should the need arise. It’s the easiest case to form consistently I have tried. Just something to think about and if your like me confuse you even more

KISS, a 6BR. A 6x47 can cause loss of hair, trouble getting asleep and can get real expensive in a hurry. BTDT. You'd be better off with a 6 CM.

 

[Sniper338]

Another for 6BR.

Dasher, I'll never build another 6br for 105's. I will say I shoot the Lapua dasher and not the Norma.

Good luck.

First choice would be a 6mm Dasher. Second would be a "straight" 6mmBR. You do not have to fireform for the Dasher. Here is how this works: FIRST fireform 5 cases. Then RE-Fire them (with a regular full power load) (Say 32.6grs of Varget and a 105) so they are "chamber specific" for your chamber. Then send 100 to Darrel Jones "DJ's Brass Service", ALONG with the 5 cases. Make 3 of them UN-sized and 2 of them properly sized for your chamber. Darrel will HYDRO-FORM them to those cases. I have had him do it for me on several occasions and they turn out so good you can use them at a match with no ill effects! Now you have a Dasher

What be the difference between a 6x47 or a 6mm creedmoor for easy of tune one of the same I think.

Stan, All I know is I tried every load known to mankind and a few others that will remain unknown in a 1-8 Hart 6x47 no turn and couldn't get it to shoot. I'm just guessing there's more data out there with the 6CM..

I think there both finnicky.

 

[johara1]

if you ever get the chance to go past 500 you may just want to use a 6br imp. it will shoot in the sub.1 range at 100 and it will be competitive at 600 or 1000. ...... jim

I don’t see any downside to the 6BRA for your situation. Just get the freebore and twist correct for your bullet.

The 6 BR works well and I have seen others use it with great success out to 600 yds. I feel it could be a little faster with the 105's but then there is the life of the brass to consider, moderate loads with 30 to 30.7 grains of Varget give long brass life...…….load -shoot, load- shoot...…. XXXXXXXXX !

 

[KenOath]

Go the straight BR, if you feel like a change of pace re chamber to BRA or Dasher.. You won’t go wrong with any, the straight BR is the closest to turn key..IMHO

 

[338rumshooter]

Straight BR, can't go wrong.
