Been reloading forever, but never done much in the way of cast. A few pistol rounds here and there over the years, but not much and no rifle rounds at all.
I bought some .30 cal cast bullets while at the LGS a few weeks back. They are at my dad's where we reload together, think they were Sutter brand or something like that. I didn't see much on the box except diameter. We reloaded them up this weekend. They were 165 grains and I threw 15gr of Reloder 7 behind it with Winchester primers.
Took them out today and ran some through my new setup, which is a TC Pro Hunter in .300BLK with 16.5" barrel, with Warne rings, and Bushnell Trophy XLT scope. I started off at 50 yards and had no consistency at all. A shot 9" off bull at 10 o'clock, then one 4" off bull at 4 o'clock, then one 3' off bull at 7 o'clock, etc. etc. I thought it was scope or rings first of course, but they were tight. Then I shot a few jacketed 110gr. jacketed bullets and saw a group, so it was the bullets.
I called the Gun Store where I purchased them and let him know I got no consistency at all from them. He proceeded to tell me I was probably pushing them too fast and probably leaded up my bore. That they were meant for Cowboy Action shooting with a .30-30 only. The bullets gave no suggested velocity or warnings on the box.
If I slow them up and drop the charge I doubt I will see a change in accuracy. What do you guys think?
