Not really reloading ROOM, but finally tested a few loads, loaded on the "new to me" RL1050, using pull down 55gr and pull down "H335" from American Reloading. 25gr of powder is standard load for that combo, and this powder is right in the ballpark.
These are coming out of my 12.5, I tested four Hornady black 77s that are rated at 2790, and the four shot average 2455. The 55 grain with American reloading powder average 2778.
For reference, here's someone else's data of factory "M193" type ammo out of a 12.5. The average of these averages is 2839. That IMI stuff really bumped the average up.
Freed up a couple roller bearing on my case pro and roll sized a couple thousand pieces of 40S&W brass. then loaded 500 of them. The STIs like 40 a bit long so I loaded them to 1.175". Got bored loading so fit a new barrel to my 6" Fat Free STI and sighted it in at 50 yards.
