I would appreciate input into my problem. I had a rock solid reload for my Nagant revolver. I used a . 312 96gr lead bullet, which I purchased, and 3.3 grains of Trail Boss. It gave me 760 fps plus or minus a fps over 5 rounds. I bought a Lee mold and cast my own bullets. They are dropping at .312 - .313. Their weight is 101 gr. My barrel slugs at .313. I noticed with my bullets, I was getting more "fliers". I saved three rounds of 3.3 gr of Trail Boss and my cast bullet. I checked them on the chrony and their speed was all over the place. Today I did some testing and produced the following:
2.7gr 2.9gr 3.1gr 3.3gr 3.5gr 3.7gr
1 dud 477.9 395.4 622.6 587.4 421.6
2 220.5 212.6 410.0 771.9 665.2 445.4
3 401.9 574.7 405.3 731.6 109.8 418.0
4 562.0 459.2 346.1 581.1 708.5 471.6
5 578.9 649.9 559.1 726.6 425.4 313.5
Note: All shots were made from the same cylinder and numbers are in feet per second.
I've only been reloading for a year or so; consequently, feel free to question what I'm doing. It seems like there is something else at play here? Thanks.
