Home Forums Hunting & Shooting Long Range Hunting 7 Mashburn Super, RL-33, 195 Berger EOL

Rechambered the Mashburn with a reamer designed for the 195 Berger and magazine restrictions. Tried H-1000 like the last load but hit pressure 2 grains before old load which I expected because of the lack of throat. Plenty of room in the case for powder still, so RL-33 was a choice.

Ran it from 70 grains to 74.5 with the bullet on the lands. Got ejector marks
At 73.5 and 74.5 but 74 was good. ?

Shot an incredible Audette at 560 with the node measuring about 2 1/2". It
Liked the powder and bullet.




Shot groups with the loads in the node. 71.5 and 72 shot great with no vertical at 560






Stayed with 72. Groups at 100 were not impressive but incredible at longer range
