I am dubious about the alleged near-equivalency of IMR4350 to W-A 30 for the basic reason that the normal charge of 34 grains* of the latter for an MV of ~2000fps in the Krag 30" rifle is significantly lighter than we need for the same velocity with 4350. The 34 grain charge indicates the burning rate of W-A 30 is closer to that found in today's IMR4895.

Fascinating... because I've always believed (just my opinion though) that 4895 was very close to what is used in .30 Ball ammo, such as M2 Ball, etc.  Wasn't W-A 30 used right up through WW1 in 30-06 Ball?  I personally use H4895 in my Garand and 03A3 loads (not for the LR though). 

I guess it was just an assumption that I made about the 4350 because I believed the ballistics to be very similar (40 gr IMR-4350/220 RN) to the original .30 Army round... however, perhaps I'm wrong about that!  Maybe a lighter charge of 4895 might be more the way to go?  I dunno… anyway, I do ok with my current loads (the aforementioned 40 gr 4350).
