4227 is recommended in an old Lyman manual i sort of use as a bible. It also has the universal cast bullet load of 10 grains of unique. I may try that along with some BP.
In case nothing works I may have to resort to your last suggestion of the earmuffs and possibly play a recording of a 105 howitzer beside me.

Greetings Again,
Have just been looking through some 38-55 data and wonder if 15 grains of IMR4227 might be a bit light. Ken Waters used 18 grains behind a 246 grain cast flat base in his 1976 pet loads for what he called weak rifles. He didn't list IMR4227 for the moderately strong rifles (including 1894) but did list 4198 and 4895 (probably Hodgdon). Sometimes non case filling loads can give spotty accuracy,
Regards Grandpamac.
