Here's a thread I started a couple years back. I stopped at 60g because velocity and accuracy were very acceptable. This was using the 130 TTSX but I bet you could get close to 3300 without excessive pressure especially with a 24 inch barrel. Biggest trouble is finding RL26 or almost any Alliant powders around here....
