Deerless Posted February 14, 2022 Report Share Posted February 14, 2022 Love my Sako 75, 25-06 standard #10 twist with Barnes 100grn TTSX at 3200fps. I’ve got an itch to have one built, but perhaps with #7.5 or #8 to try some long range targets using Berger 133’s. I would still like to use the 100grn Barnes for stalking, but finding conflicting info as to suitability with these twist rates. Has anyone got experience of the Barnes with these twists or could point me in the right direction please. Quote Link to comment Share on other sites More sharing options...
miki Posted February 14, 2022 Report Share Posted February 14, 2022 It's not weight it's length... although if you have a fixed diameter then the heavier the bullet the longer it is. Brass (bullets) of a similar weight, being less dense than lead, are longer to start with. The shorter the twist rate, the faster the bullet spins the longer it can be to remain stable in flight. Decreasing the twist (from 1:10 to 1:8) won't effect/limit the shorter/lighter bullets it will allow you to use longer bullets without loss of accuracy/stability.

Scrumbag Posted February 19, 2022 Report Share Posted February 19, 2022 Miki has it pretty much spot on I think. I have a 257 Roberts that when it's barrel goes I'll probably get a faster twist put on it. Scrummy Quote Link to comment Share on other sites More sharing options...
