I don't have the Super Tuned, but I do have the hardened chrome version and I can tell you it is smooth as butter and shoots lights out in a ransom rest, way better than I will be able to shoot it

Actually was probably using 3.9, bullets were tumbling at 21feet

Yes I’m using the Lee die, will be doing more testing after vacation

I will be using a epransom rest and chrono after vacation, as for the 3.4 grains for 124, that might have n been wrong

True, will be doing that after vacation

I have only been reloading for a couple of years and recently started having weird problems. I have been reloading 9mm coated 124 SWC from Missouri bullet over Win 231 right around 3.5 gns. Shot about 500 with no problem, just using them for IDPA practice, not looking for any particular load, just wanted something for the wife and I to shoot.(this was my second 1000 from them) along the way I started getting rounds that tumbled/keyholed. So I thought I would try a heavier bullet for my next batch and bought 147 SWC coated from Precision bullet. After several attempts to get a good load between min/max, I began to have the tumbling issue again. The only constant between the loads was powder and primer. OK, new powder, Sport Pistol, three different loads, 3.2, 3.4, 3.6. Also bought a pkg of 147 Blue bullets to try also. The Precision bullets still tumbled about 1/4 of the time, but not with the Blues, so at the end of all this, the only real difference in the bullets is that the Blues have a groove cut at the bottom of the casting and the others didn't. Any thoughts, recommendations? Thanks

I made two new loads last night, 3.5 and 3.7 but have yet to try them.

thanks, next batch I think I am changing to WSF

I know this is an older thread but I just bought Precision coated 147 swc and am looking to see if anyone has a good load for 231, started at 3, then 3.2 but my bullets are tumbling
