Good evening gents, I was able to find a box of 110gr Varmageddon bullets in .308 Dia just days before receiving my new to me TC Encore with a 16.25 inch 30 Carbine barrel. This bullet has been found to be too long for magazines in the M1 but with a break action, the ogive and tip should be spot on in that chamber. Working with IMR 4227 and H110. I will try to sacrifice a couple empty cases for chamber testing and start playing with max COAL. I am also without the comparator guage for the time being. Initial thoughts on starting at low jacketed velocities????

Typical weight bullets for the 30 Carbine?

90 to 110. There is some listed data for 130s but it's rare.

I looked at the bearing surface on the Varmageddon bullets and could set the seating depth to the same as a 110 fmj but the COAL would add .261 to the new load. Ogive is almost dead on a 110fmj

Should clarify, starting at the low end of listed load data, wouldn't be going subsonic.
H110 has been said to be the original 30 carbine powder, if not it's close to optimum.
At a 1.940" LOA, 16.0 gr. of H110 has a 98% fill and GRT predicts 2125 fps @ 45k psi out a 16" barrel.
I tried single loaded 110 gr. SP bullets out of my M1 carbine and the 1/20 twist didn't spin them fast enough for accuracy.

COAL 1.940, 13GR H110. 110gr Varmageddon. All chamber and extract. Might end up being too much for not enough to gain but worth the experiment.
