Tried out some Missouri Bullet Company 95 grain round nose cast bullets today.

Here's my thoughts. I used Titegroup for all loads here. First, cast bullets are a strange beast. I have shot about 800 of the Berry plated 100 grain bullets. For those, I found 2.8 grains is pretty good load. Brisk, but not bad for recoil. You can easily hit up a double tap without difficulty.

The plated bullets are slippery, don't need much expanding to fit, and need a little more snug taper crimp to keep from sliding back.

Cast bullets, on the other hand, are .001 wider, need much more expanding, and were in general a PITA for someone who has never used them before. They are slimey due to the lube, get your fingers dirty. I didn't expand the cases enough, and I think the bullets weren't seated square with the case which affected accuracy. A lot. I had stuff flying all over the target. It was pretty embarassing to see.

Shot 25 rounds with a .970-.973 OAL loaded with 2.5 grains Titegroup. That is a light load based on the Lee and Lyman manual. I never found a match for these bullets so I started low, and went slow.

These were okay. Shot a little bit low it seemed. Just a hair. Super light recoil. Quiet, light, and clean.

With the same bullet, at 2.6 grains with a COL of .950, recoil was notable stiffer. Accuracy was okay. A touch better than with the 2.5 grain. I don't shoot with a rest, just by hand so that's a factor.

Lessons learned:
Cast bullets are a strange beast.
Expand the case aggressively.
Seating is a challenge. I had much more variance in COL vs the plated bullets.
I didn't need hardly any taper. I could pound on the bullet and it didnt budge a bit. They did have an obvious bulge, but I measured the case diameter and it was still in spec. Really no chambering issues and I suppose that is what matters.

Hard to beat for the money. I paid, after tax, $34 for 500 of them at a local store.

Sounds like you have identified some of the mistakes in your first batch of reloaded lead rounds. Keep going at it, you will get the results you want. I use the MBC bullets in 45 acp, 45colt, 9mm, 38/357. They provide some of the best accuracy that I have ever achieved.

Its interesting to note that I have a gun that has never shot anything but MBC bullets its entire life. I bought it new and have put several thousand through it.
