johnnyb0_1 Posted January 16, 2018 Report Share Posted January 16, 2018 What bullet weights will a 30 cal. 1 in 9 twist barrel shoot. Ie lowest to highest that will be supported. Thanks. J. Link to comment Share on other sites More sharing options...
gbal Posted January 16, 2018 Report Share Posted January 16, 2018 johnny; . Google the " Berger Twistrate Stability Calculator." You will get reliable info on the stability of bullet weights in cal/twist-in some detail-eg marginal...stable...well stable 'on a scale.. It is a scale variable,which is why one rifle might be reported as ok (just)by it's user and another with nominally the same twist (it can vary a little by make,despite what is claimed) may well be marginal. That's not to say someone with exactly your rifle model/twist won't be useful info as well,but if you want general acceptable range of bullet weights for any calibre and twist,Berger is your source. gbal ...

6mmBR Posted January 16, 2018 Report Share Posted January 16, 2018 What cartridge are you planning on chambering it in? A 1 in 9 will shoot from 155-230 in a .308 but in a magnum cartridge like a .300WSM proberbly 200-230 grain would be more appropriate for a long range bullet.

johnnyb0_1 Posted January 16, 2018 Author Report Share Posted January 16, 2018 Gbal, thanks for that, very useful. Dave, was hoping it would cover 155's up to 200gn in 308 and as you state it does indeed. Thanks and regards to both of you. JP. Link to comment Share on other sites More sharing options...
