It took me quite a while to work up an accurate load for my traditions deerhunter 32cal (1:48"), but here is what finally worked for me.
30gn pyrodex p
3/4" .020" pillow ticking square patch lubed with 50/50 beeswax/crisco trimmed at muzzle
311 cast round ball resized to .308
I load powder, tap the rifle a few times near the lock to get some powder into the bolster, then short start the ball over 3/4" lubed square patch. Trim the patch flush, long start, then ramrod home verifying the 'loaded' mark on the ramrod. She always fires, will shoot cloverleaf groups (bench rest) at 25yds, and I never have to clean the barrel while shooting (50+ shots). I do clean the nipple (pick) between each shot.
30gn Pyrodex p seems to be the most accurate for me and cleaner than FFFG. The .308 resizing made loading a lot easier and increased accuracy. I resize and load off the sprue. Casting my own balls, cutting/lubing my own patches makes the 32 very economical to shoot. Starting to punch/load my own caps, don't have this tuned yet.
The 1:48" twist is just too slow for 32. I have not had much success with lighter loads than 30gn. A 110gn 32 maxi ball shoots very poorly (twist too slow) even at 50gn of pyrodex p. At 311/308 rb with 30gn of pyrodex p she is a bit too hot for squirrels, but makes an excellent rabbit/chuck gun out to 50yds.
Bottom line, a lot of fun to shoot and does not beat my face and shoulder up after a long day of shooting.
