Hi all was looking at peoples experience with this twist rate. Question is lm looking at shooting 75g Speer HP In a 1-7.5 twist rate, does any know if they will shoot accurately enough?

What cartridge?

If the bullets don’t blow up from being overspun it should still be accurate.

Question begs to be asked..... why??

I agree Ben, twist rate may blow up the 75gn speers. Most use that twist rate for 100-115gn projectiles.

Thinking of buying a Howa 6mm creedmoor barreled action. I have shot the 75g hp speers out of 243 and was very impressed with there results and they are cheap. Was looking at this as an alrounder set up.

If you're going for a 6mm creedmoor you'd be better off looking at 95gr pills and heavier for what is a pretty aggressive twist rate.

nosler ballistic tip varmint bullets will often withstand fast spinning when conventional bullets will not.
this is probably due to the solid base of the nosler jacket.
at least this has been my experience in 22 cal fast twist converted to varmint rifle.
at the fast spin rate they have very explosive terminal performance.
keep safe,
