Two questions:

Is this the Lee GB known (IIRC) as the 312-155?

How did you and they do?:Fire:

i'm not sure if it was 155...it is three crimp groove, flat nose, gas check.

since i only did limited load development, i did not expect much. i did not play with seating depth, nor fine tune the load, and did not chrono the load, only est velocity. i have not cleaned the rifle in 70 rounds. the muzzle looks fine but have not patched the bore to check for lead.
i fired a sorta small group...third small at 4 inches out 14 shooters, and the only one wiht cast.
the object was to have fun without beating on my shoulder.....i shoot left and my right clavical has been sore since shooting full power 180 7mm mag loads in a match a month ago.
i still have the 314299 and the gb 200 gr to try.
