Load for 45 Colt, 300 LFN from SPEER reloading manual needed

[GeoDudeFlorida]

Have you seen 20kpsi tier 2 loads collected anywhere? One might hope Lyman might break them out but I'm not holding my breath...

Brian Pearce.

What you are omitting is that loads for cast lead and copper jacketed bullets are not the same. The scarcity of screaming hot 300 grain boolit loads from well respected manuals - even the infamous Speer #8 - is telling.

The loads are different because of pressure and material. A lot of loads are tested in Lyman #2 at 16bhn. Linotype is harder and the same bullet can have different data. I cast at bhn 12 for magnums and still use upto jacketed data in 357 mag. My cast are powder coated if that changes anything in your mental picture.

Just want to point out that Brian Pearce got a 320gr to 1068fps with Longshot.

I think I did, Well, I should be more specific.

If Murbach was using lead bullet instead of jacketed one as listed...
