SIG M28 and Sako M39 New Pet Load

[tmanbuckhunter]

Recently acquired an older Lyman 311332 a few weeks ago. I cast up a decent pile of boolits and squeezed some NRA 50/50 into the grooves with a Sage's gas check. Loaded them over mildly increasing charge weights of 5744. Most groups were very similar to these so I know it's repeatable. I just liked the chrono numbers on these loads.

Lyman 311332
Sized .311, Sage's Copper Gas Check, NRA 50/50, Lyman No.2 Hybrid Alloy
21.4gr of Accurate 5744
PPU Brass
CCI LR
2.780" COAL.

Velocity was 1720ish for both, with a spread of 18-20 for both. Both groups were shot at 100 yards. I've always shot a Ranch Dog TLC311-165-RF out of both of these rifles, but I think I know what I will continue to shoot now.

I would stop my load development right there ! Good job !

What is the weight of the bullet fully dressed? Somewhere around 195-200gr? Good shooting BTW!

I have tried that bullet in an 03A3 and like it. I'll try your 5744 load in my M-39 and see how it does.

Boy, hard to beat that! Good load and good shooting

186 actually. One cavity drops 185, one drops 186, both cavities drop bullets +/- 3/10ths or so. I don't weight sort any tighter.

Man, considering that the same charge weight had similar numbers and performance out of both guns, it shows I'm onto something there. A real pet load I think.
