One of the 6.5mm types 1-8 twist . I can run slightly under 100 grain up to 140 grain or a tad more in my 260 rem . That said i can do fine from Muntjac to the biggest stags just using the 100 grain Barnes tTSX copper .Guys
what would be the best all round calibre for all species of uk deer i’m running a 222, 243, 6.5 x 55 and 308 at the moment
will keep the 222. but possibly looking to go to one calibre for all and as it’s loomingand will shoot well with copper
cheers

Could maybe be done in your 6.5 , if it handles that range of bullets with its current twist rate ? After you leave this bullet weight range your into the magnums to gain a noticeable amount tbf
