Today I tested the H4198 in 7.62x54r as a reduced load. Using a 1935/36 Tula 91/30 it produced just under 1" groups at 50yards with 24.4 grains under a 150gr Sierra Hot Cor .311 bullet. This was a fun plinking round... I expect similar performance in the m44 and t53. I will check it out tomorrow! Thanks.
