My pet load is 76gr of Rl-33 under 140 Hybrids @ 3190. That is in a 24" #3 Rock barrel. Zero pressure signs, just stopped cause the load is ridiculously accurate for a 7# gun. Consistent .3-.4's. I'm sure I could go higher just not seen the need. I may see what I can squeeze out of her later but for now gonna run her at where its at.
