Thanks for the kind defense, but at least I got Rick to stop by!
And not to veer far from my very first statement (no expert here), while I did go from memory before, now I’m a bit confused…Went and looked at TM 43-0001-27 and the M95 and M210 are listed as percussion primed. The M97A2 is listed as an electric primed version of of the HEI and I don’t see an electric primed APT loading. The M96 Incendiary is listed as percussion primed. (elsewhere in COTW I see it listed as electric primed!) The percussion primed issues are indicated for the M3 and M24A1 guns. The M97A2 and other electric primed rounds are indicated for the M24A1 only.
I have an inert electric primed M96 of early 1950’s vintage (thus my previous investigations into the subject). Looking at Tony Williams’ fine books Flying Guns and Rapid Fire, it seems the M24 (not “A1”) is electric fired only. The M3 is definitly percussion firing.
So…Perhaps the M24A1 can fire both electric and percussion primed and the designations M95, M96, M210 etc. do not indicate primer type?
I need some learnin’ here!
