This experiment started because I bought a quantity of .32 cal. JSP 170gr. bullets listed in Uncle Henry's. (If you are in Maine, you know Uncle Henry's - or you could look it up) Anyway, they worked well with 30.0 gr. Vihta-Vuori N-133 powder in both a Marlin 336SC and a Winchester M94. 5 in 4.1" @ 100 yd. from the Marlin, and 6 in 6.3" @ 100 yd. from the Winchester. This is wrist-rest from the bench, a technique Pietro has explained in other posts. The sights are peep rear on both rifles, bead front on the Marlin and post front (I just filed off the bead to leave a skinny post) on the Winchester.
Then, I looked at a box of CB loads I loaded for the M94 before I had the Marlin, and said to myself, "I don't need both rifles sighted with JSP's, so set the sights back where they were and shoot a group with the CB load." This was the Lyman 170 gr. GC 323470 Loverin design, 17.0 gr. MP-5744, and CCI 250 primer. I loaded these 20 years ago, and don't have any more of that powder. 5 went into 4.8" @ 100 yd., still very satisfactory.
I say very satisfactory, because I am 75, hard to see the sights clearly now, little tics and twitches to the bench position can throw a shot out a couple of inches, and so forth, but these groups from hunting rifles are still beer-can accuracy at 100 yards, good for me.
