What is the best rate of twist for .243 assuming 22 inch barrel and 80-100 grain bullets? I will be hand loading for target shooting at ranges to 500 yards. Thanks.
To be fully stable in all reasonable atmospheric conditions with a 100gr bullet in .243, you need a 1:8.5 or faster twist.What is the best rate of twist for .243 assuming 22 inch barrel and 80-100 grain bullets? I will be hand loading for target shooting at ranges to 500 yards. Thanks.
1:9 might be better than 1:10. My 19" Sako carbine, 1:10, doesn't seem to do as well with 100s for tight groups as it does with 85s and lighter. I only tried one effort with Noslers, though.
That will stabilize 100gr bullets down to 32F at sealevel. So it'll be a bit of a fair weather rifle, but OK for most things.I am looking at a Savage with a 1:9.25 twist. Too slow?
