8" barrel VS 4"barrel

Snakeman · 12-30-2005, 06:11 AM

Some of my shooting friends who shoot the Walther GSP (has a relatively short barrel) complain of grouping quality with some -not all- .22lr ammo. Neither of my Haemmerlis (208, 280 -both with longer barrels then the GSP) have this problem. As not all .22lrs use the same powder with the same burning rate, IMHO it may be a case of accuracy harm caused by uncomplete combustion of the powder in the shorter barrel of the GSP.
