Ronin Posted July 10, 2012 Report Share Posted July 10, 2012 Looking for advice from people who HAVE a 6mm BR. Wish to know two things please; 1 - what twist rate you have 2 - what range of bullet weights THAT twist rate shoots accurately Im speccing a BR build and want to get TR correct - 70 - 105g bullets for me would mean 1-10 Would the 1-10 overspin the lighter bullets.....?

I don't think you will go far wrong with a 8 twist mine shoots 87 vmax to 105's with pin point accuracy. I have shot 65/75s ok but the accuracy with the others were superior. As I said I'm pretty sure the 10 twist will be useless with any 105s Cheers Dave Link to comment Share on other sites More sharing options...
Elwood Posted July 10, 2012 Report Share Posted July 10, 2012 Both of my barrels were 1-8 twist, the Kreiger (Joel Russo stock) would shoot 105's superbly, the other which was a Pacnor barrel wouldn't shoot the 105's, although it shot the 90 and 95 grain bullets a treat.

gaz6br Posted July 10, 2012 Report Share Posted July 10, 2012 I have a 1/8 twist border on mine it shoots 80gr bergers and 105gr Amax real well, id say it shoots the bergers alittle better but i did a six shot group the other day with the Amax at 100 yards and coverd it with a 5p, on a good day the bergers punch tiny little clover leaf groups, all is good Link to comment Share on other sites More sharing options...
Scotch_egg Posted July 10, 2012 Report Share Posted July 10, 2012 1-8" on my BR as you know ,,,,, For the 105gr bullets you do need the 8" twist. However it really does depend on what the intended purpose of the rifle is. Link to comment Share on other sites More sharing options...
british bulldog Posted July 10, 2012 Report Share Posted July 10, 2012 Pac-Nor 1in8" twist on mine it shoots 85gr-105gr into .25", I have tried 55gr-80gr but they would only shoot into .5" My pal has a 1in10" twist .243 and it won't shoot 100gr bullets at all never mind 105gr's Hope this helps.

22/250 foxer Posted July 10, 2012 Report Share Posted July 10, 2012 I know where there is a stainless m595 action. With 22/250 mag which will feed the 6 br. If any one on here is looking for a action to build one on. Link to comment Share on other sites More sharing options...
1066 Posted July 10, 2012 Report Share Posted July 10, 2012 I have a 1 in 8 Shilen barrel with 4 groove ratchet rifling on my br. Seems to shoot everything from 69 FB Bergers to the 108gn Bergers well. Link to comment Share on other sites More sharing options...
mole-e30 Posted July 10, 2012 Report Share Posted July 10, 2012 I have a 1:8 twist Bartlein on mine It has done everything from 66gr G&C Flat bases up to 105gr Berger VLD's all have shot wonderfully. Cheers Bruce Link to comment Share on other sites More sharing options...
skany Posted July 10, 2012 Report Share Posted July 10, 2012 Im runing a 1-8 pacnor Andy 105 amax 65 vmax 55g noslers all bughole my freebore is however in the low 70's which for a 1-8 twist is not the norm! i wanted this to do it all & have to say it did/does! if i was building a out & out foxer id do it differntly from what i read on the 6mmbr fourum a zero freebore 1-14 1-12 will get close to 4k with 55g bullets! see here http://6mmbr.websitetoolbox.com/post/55g-bullet-in-a-6-BR-3603338 ive seen 3800+ with mine but think im running in the low to mid 3700s at the mo as i started to see pressure! im sure a 1-8 would be a fair bit slower mind! not sure its luck or the shortish free bore that makes mine work so well with the light bullets!(they are still nowhere near the lands) cheers Andy Link to comment Share on other sites More sharing options...
Ronin Posted July 10, 2012 Author Report Share Posted July 10, 2012 Gents thankyou for the replies so far. Any other BR users? Link to comment Share on other sites More sharing options...
garyw Posted July 10, 2012 Report Share Posted July 10, 2012 I had a cooper 1-8 shot mainly 75 blitzkings and 87 vmax with very good accuracy for vermin.it would shoot 55 blitz kings accuratly but never went with them,the effects with the 87 vmax on vermin were "very pleasing". general rule of thumb with the 6br is 1-8 to shoot everything up to 105gn with good if not pinpoint accuracy.

baldie Posted July 11, 2012 Report Share Posted July 11, 2012 I,ve only ever run 1 in 8" twists on the two i,ve owned Andy, and they have shot everything from 75 grains upwards, even the 107 sierra,s Built dozens now with a 1 in 8",s but also have built quite a few on 1 in 12",s to shoot the 58 grain v-max. I have a reamer cut with a throat specifically for this bullet if you need to borrow it. Link to comment Share on other sites More sharing options...
Offroad Gary Posted July 11, 2012 Report Share Posted July 11, 2012 Someone in our DMG has a PRS one, 8 twist, shoots 69gn bergers for vermin and 105 gn hornadys on Reds at ranges some people think silly, holds sub .25 moa at 400y no probs. You got that tikka out the cabinet then? Link to comment Share on other sites More sharing options...
Ratwhiskers Posted July 11, 2012 Report Share Posted July 11, 2012 So the Ratwife's BR must be the one off in the pack..... 1 - 10 twist. She only wanted it for a hunting rifle and had not intentions of going further then 95's, it actually shoots 88's like it's on rails I doubt greatly that it would handle anything over a 100 F/Base.

Finman Posted July 11, 2012 Report Share Posted July 11, 2012 Mine is 1:9, Border barrel. Shoots 65gn, 70gn, 75gn and 87gn bullets all in the .2s. Never had I the desire to shoot heavier, since the 87gn Hornadys do all I ask of the gun (500yds bunnies and 250yds deer). Best wishes Finman Link to comment Share on other sites More sharing options...

gazzar15 Posted July 11, 2012 Report Share Posted July 11, 2012 Dave, thats extremly kind, thanks. Ronin My Blaser is a 1/8 twist but seems to like the midrange bullet weights i.e 70 -80 gr. It doesn't seem to be that tolerant with 105 bullets though I intend to try other powders. Link to comment Share on other sites More sharing options...
