Getting ready for my new rifle (.32 caliber). This rifle I will cut at the muzzle and not try to do pre-cut patches. I will be trying both .310 & .315 balls with patching material from .010-.020. Half the rolls I soaked in pure Neatsfoot oil and the other half of each size in my own patch lube. Will be trying loads from 20 grains to 40 grains. Going to take a while but I am one of those who really like to develop a load and take the necessary time to do it. Going to take many trips to the range and lots of small targets. Don't care where they print on paper as long as it is reasonably close. When the final ball size, powder charge, patch lube, and patch thickness has been decided then and only then will I look at adjusting the sights.
Maybe not how you do it but if you only change 1 variable at a time you will find the best load. Has always worked for me.
Mike- my little .32 had wide lands, narrow grooves, exactly opposite what we usually want. However, I started off with a Lee mould casting .311's- both round and both .311". I used .020"denim to .0235" mattress ticking patches - loading was simple and by choking up on the rod, I didn't need a short starter to get those combinations started. With a water based lube, spit or with Neetsfoot oil or saturated with mink oil - no wiping at any time for an entire day's shooting.
I tried Hornady buckshot and found at .320" and having antimony in them, they were too hard to load easily. I bought a Lee .319" mould with which both cavities cast .320" x .320" round balls.
I started off with the .019 stretchy ticking (yes-no synthetic material in it) & the loading was easy. I switched to .0215" ticking, then 10oz denim and finally the mattress ticking of .0235", all loading easily. I was using those mattress ticking patches the day I tested with mink oil. The first shot was a little grabby going down, but the 5/16" rod handled it just fine. After that, loading was
easy as at any other time & I could load it without the short starter as well, choking up on the rod and pushing the patched ball into the muzzle and down a few inches, then all the way down with the rod.
This is the muzzle of that bl. You can see the narrow grooves and wide lands.
Wider grooves and narrow lands (Forsyth-type) loads even easier, but is not PC for N.A., if that matters.
