Was able to get out this morning and shoot my 1933 Mosin 91/30 HEX receiver rifle I had reworked a couple months back and try out the new Lee .312″ 185 gr. RN bullet I had cast up. The bullets were cast from Wheel Weights + about 2% Tin and quenched straight from the mould. The next day they were sized to .314″ in my RCBS Lube A Matic using Lars 2500+ and Gator checks.
Cases were once fired PPU brass I got at the LGS they get from the local gun range. I full length resized the case this time around and trimmed them to proper length and resized the case neck using my NOE .312″ expander plug. The throat is pretty deep on this rifle so I couldn’t seat the bullet out as far as I wanted so I seated it half way on the middle driving band for this test load. I used 19.0 grs. of Alliant 2400 and Winchester LR primers.
For this test I loaded up 25 rds. as I have installed a MOJO rear aperture sight on the rifle an the original factory post so I knew it would take a few rds. to get it on target an leave the rest to chrono and do some accuracy test. I set my target up at 50 yds. which is a far as I can shoot in the back yard range,below is the final result for today’s shooting and I had another target with the shots in the orange square area once I made the final sight adjustment but was unable to retrieve it before the weather moved in. After firing those 25 rds. the bore was nice and shiny with only a few burnt powder residue specks here and there. I’m pretty pleased with the initial results an will be trying a couple different loads in a few weeks as well as a couple more of the 2400 loads in larger increments as I have room to increase it.
