I picked up a Howa 1500 6creed from a member on here and thinking it’s a 7.5 twist. I may pick up a Tikka 243 for the kids and not 100% sure but kinda thought they were 10 twist. Just looking at what bullets I have and what I’m finding in stock. I thought loading some 55-70gr for this summer for prairie dogs (mainly use the 22’s and 17’s)

Didn’t know if that 7.5 would work at all with the 70’s
