just want to verify the lower the twist as in 1:8 the heavier the projectile/bullet it can fire safely
what should i be using in 1:8 twist 65 grain or higher?
Will a 1:8 twist still fire 55grain ok or will it destabilise the bullet due to the twist?
i am only using factory at present till i figure out what i need to reload
thanks
What calibre might help..??
There are a lot of factors that are involved with twist rates and bullet weight plus others like bullet shape, length.
In the old days when bullets were not made to the same quality as they are now, shooting a very light weight bullet in a very fast twist rate might cause the bullet jacket to fail (fly apart) due to the pressure created by the internal lead plug.
These days the problem is with bullets that are too long and too heavy for a slow twist rate that the bullet will NOT stabalise and will tumble instead of spinning correctly.
