I recently made up my first reloads. It was great fun. Here is some info on what i did. I hope others can share info and help me dial in a load that this gun likes. Maybe someone already has data they can post.
Load #1:
Bullet:
Hornady V-Max 50 Grain
Powder:
28 Grains Winchester 748
Primer:
Federal GM205 small rifle magnum
COAL:
2.245
Average Chronographed Speed:
3493 fps
Best 100 yard Group:
.623
Average 100 yard Groups:
Over an inch
My thoughts:
I am not sure on the COAL for this gun. I think I might have these too long. This load didn't group well. Even though it was loaded a couple of grains below the max listed in the Speer manual, this load was pretty hot as seen in the speed.
There could be 4 issues here. I used a small rifle magnum primer (suggested by the guy at the reloading shop). COAL might be too long. Might be loaded too hot. And finally, this gun might not like 50 grain bullets. It does like 40 grain Wichester Varmint Factory loads, which I find strange for a 1 in 9 twist barrel.
Load #2:
Bullet:
Hornady V-Max 60 Grain
Powder:
25 Grains of IMR 4895
Primer:
Federal GM205 small rifle magnum
COAL:
2.251
Average Chronographed Speed:
2954 fps
Best 100 yard Group:
2.173
Average 100 yard Groups:
Over two inches
My thoughts.
Again COAL might be an issue. This like the other load didn't group well. This load according to the chronographed speeds was not real fast for this bullet. This gun with a 1 in 9 twist should like heavier bullets. Maybe I need to go even bigger with the bullets.
I am a little puzzled and looking for suggestions. I sure had fun experimenting with my first loads.
