So I ordered a few boxes of NSA .22 20 grain .216 through .218. I’ve found my m3 compact likes the .218 in the heavy and pellet barrels most. Or at least I had the best accuracy in .218. Anyway when I increase the weight of the slug the length will increase also. So should I lock in on the .218 for all weights or try other diameters in different weights too? Not sure if the length of the projectile may affect how much the barrel will like to “hug the slug” if you will.
