You are correct. I have no experience in loading even though I have been CAS shooting for 5 years. Preparing to BUY a reloader and ammo components. Therefore, I can not test the powder in brass. I would be using round flat point lead bullets with roll crimp. Shot rifle with bought 1.573 rounds and it was not smooth. Tried 1.55 rounds and it was smooth. This was verified with Pioneer Gunworks tech. Do not want hot loads, just what will work with low recoil and clean burn as possible.
The advice on other forum was good But was looking for someone that has used Trail Boss in 45LC that had COL down to 1.55 because I have no components to test yet. Otherwise will have to look for another type powder and/or bullet to purchase. Because I have already purchased a '73 from Pioneer Gunworks customized and short stroked I plan on using their advice and experience with the ammo.
Again thanks for all input.
