Hello all,
some weeks ago I get my new Jäger rifle with a cal. 50 Getz barrel with deep radius grooves. I have done many tests to get that rifle shooting accurate.
I have tried .490 and .495 rounds with 0.017 patches with moose milk. Powder was Swiss No 2 and Wano PPP (which means FFF) 55 grn. Without wiping between the shots I got no accuracy. When I wipe the barrel between the shots with moose milk I recognized that there was a very hard croud of residue near the bottom.
My impression is that the patches are to thin for the deep radius grooves so that the patch cannot fill and 'wipe' the ground of the grooves.
Members of my gun club gave me the advice to increase the load so that the the round ball will be compressed and fit in the deep grooves while the powder gets off. Moreover they mentioned to try a thicker 0.020 patch so that the deep grooves are 'filled'.
With my Green Mountain barrel (cal. 54) a .535 round and a 0.017 patch with moose milk and 60 grn of Swiss No 2 I get a very good accuracy without wipe between the shots.
So I am a little bit dissappointed with the Getz barrel.
Perhapes you have good advice for the Getz barrel.
Thanks a bunch in advance !
