    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.

    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.

    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

    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..

    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 !

    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
