Thread: BSA 243 at the range

Greetings,
Most .243 rifles will have a 10 inch twist barrel. This may be marginal with some of the longer projectiles so it would be a good idea to measure the twist. Not surprised the Corelokt shot well as they are a short projectile. The sudden loss of accuracy would suggest a stability problem to me, unless something came loose. These days .243 rifles often have 8 inch twist barrels to stabilise the longer pills.
GPM.
Just checked. The 90 and 95 grain Sierra TMK which I think is similar to the Game Changer both require a 9 inch twist or better.
