I have been shooting the APP (Shockey's Gold) for the last 2 seasons, and was never happy with my groups. I took it out one more time in August and at 50 yards shot basically a vertical stripe on the target. I.e. my windage was near perfect while my elevation gave me a 6 shot group over 12"! Sometimes all the powder would gas, and some shots I would see sparks. That was the last straw, I threw the stuff out and picked up som T7 FFG.
Last weekend I took it out to sight in for ML deer, long story short it shoots much better. I am not a great shot with open sights, but shoot a much better 6" group at 100 yards, and very tight at 50. My confidence in the load I worked up is very high. (Hornady sst 300 infront of 110 grn T7).
Working up my load: It is much hotter than the APP. I got complete gas-out at all charges. So I immediately backed down my powder amount to 80 grn. My groups were not consistent at 80, so then I jumped up to 110, with the thought I would back down from there. I shot well at 110, but the recoil was hard! I got a good 6 shot group at 50yrd and shot a great 4 shot group at 100 yards, so I just left it alone.
One thing I noticed is that a get a horrible hard crud ring down near the breech plug with the T7. When I tried to swab between shots, I almost could not get the plunger back out. Have any of you had that problem with T7?
Will I be able to reduce that problem if I work my charge back down a bit?
Thanks for your input. I have probably put about 50 hunting rounds through my ML this summer/fall getting it dialed in and for the first time feel like I am pretty deadly with it.
