Well after many months I finally had time to go shoot the new (1962 vintage) .300 Mag I traded for in January. It appeared to be unfired and was packed in the original box. The only markings on it are Belgian proofs and "Alaskan Rifles - Made in Belgium". The original box it was in has "Dumoulin Rilfle" pencilled on the end flap, the jewelling on the bolt looks right for Dumoulin so who knows.
I do like the way they jewel the bolts too.
Anyway I grabbed 3 different cheap loads just to try, since I haven't had a 300 Mag for a while I don't have any handloads yet.
The 150 gr. Federals really scared me, 4 1/2" pattern at 100 yards. I was kind of worried it was a combination of me forgetting how to shoot and something bad wrong with the rifle.
Moved on to the 165 gr. Federals and the 3 shot groups came down to 1 1/4". Now I'm feeling a little better.
Finally the 180 gr. Federals loaded with Sierra Gamekings (told you they were the cheapest I could buy), and the first group was 1.15", then the second group with these went .97".
Happy at last!!! Tried the 150's again and back to 4-4 1/2" patterns so I gues this one likes the heavy bullets.
