I have a long history with IMR4064 but haven’t used it for years, when Varget came out it seemed to work better for me. I’m going to try IMR4064 under the Hornady 200 RN in 35 Whelen. I have all three flavors of 4350 but since I have about 11 pounds of IMR4350 I’m thinking I’ll play with it for awhile. I’m hoping to load some 30-06 and 38-55 tomorrow, cases still in the cleaner. I’m going to see if 4198 will bump up a .374″ bullet to fill a .380 ” bore. I have some bullets bought for a 375 Winchester quite awhile back that I’m willing to sacrifice for the cause. That .375 seems to like a Lyman 375449 bullet better anyway. I have about a pound each of H4198 and IMR4198 but I think either will do. Was tempted to fire up a casting furnace today to warm the place up, single digit temps is a bit chilly for an old guy in Texas. Maybe tomorrow. Supposed to be about 7 degrees in the morning.
Gonna need a truck to haul all this ammo and related guns out to the range when the weather clears!

A4064 and IMR4064 may be very similar but I found when dabbling with three flavors of 4350 that they needed to be treated as different powders so will do the same with H4198 and IMR4198 even though I haven’t noticed a difference. We’ve been told there may be variations from lot to lot of the same brand powder but other than one lot of bad powder I’ve never noticed much difference. Unless we’re loading max or near max loads I don’t think it will be a safety issue but sometimes one flavor will work better than the others; just like some primers, cases and bullets seem to do better than others. Finding a combination that works is what makes loading interesting!
