If in fact you have hornady item#45204 245gr
I talked to hornady 1-20-20
Purchased box of factory loads to compare to my handloads. Hornady recommended not to push these faster than 2500 fps. Factory loads chronographed 2200ish. Factory loads c.o.a.l. 2.235" when talking to hornady they recommended 2.245". I started on the high side with lil gun and had pressure spikes and exceeding 2500fps. Checked side by side with two different chronograph's. I settled on 33.7-33.8 gr lil gun avg 2139.4fps.5 shot string. Retention for my test was 239gr copper was shedding but still in tact.
These are just tests that work for my use only. Hope this helps. Good luck and please reload responsibly
