Walter...It'll be very interesting to see how those shoot....I don't engrave them that much....

mine are seated as follows, Remington 03 USMC barrel (shot out) 3.150, MK1 03, NOS 2 groove, 3.260, Rock Island 03, NOS 4 groove,3.260, Rem 03A3 A4 2 groove, 3.260, 03 Sporter w Star gauged, 4 groove barrel, 3.185,Smith Corona w/ near new 4 groove barrel ,3.70

Amazing how different the barrels are...I got mine seated so there is a very small jump... Dan

So I’m also going to load up 20 rounds of the 312299. I’m thinking about 34gr of H4895. GC, .311”, Glens black moly and a coat of BLL.

I would try five in the 28.5 to 30 grain range

30 would be more appropriate.

34gr doesn’t seem out of line.

Walter..it may not be out of line..but 32 to 34 grains is usually what is used to get m1 Garands to cycle and feed reliably but is understood to also be above the desired load for optimal accuracy...

Waco, listen to Dan and Fiver, there's a larger picture to what they're saying.

There are three tricks to getting a cast bullet to shoot straight. First is a good rifle, not as good as you might think necessary. Second is proper physical fit of the cartridge and bullet for exactly what you're trying to do and at what speed. Third is matching the load and the alloy to the rifle. That's it, though you can spend a lifetime trying to catch just a glimpse of how to accomplish the second or the meaning of the third.
