My Handi rifle Classic carbine in .45 Long Colt is looking good so far.
I did some fiddlin'. Here's what's goin' on. Using a once fired Hornady .454 Casull case, I gently pressed it in the till it bottomed out, used a depth mic and took a reading. Trimmed the case .005 more than that reading for a finished length of 1.305. That's a lot longer than ANY .45 colt case. I need that extra length though, so this is good.
Using an NEI 455g flat point gas check boolit, I came up with an OAL of 1.854. The action will shut on that, engrave the boolit into the rifling and still extract with ZERO issues. I did this several times. It does engrave a little on the heavy side but it pulls right out with no tug. I did NOT crimp the case but I saw NO change in OAL so I'm callin' it good.
That OAL gives me a seating depth of .580 which leaves room for exactly 6.5g of Trail Boss with no compression.
Should I even use a crimp, this being a single shot? I know it would change the pressures, but as heavy as it engraves I don't really see a need.
What's yall's take on that???
