I average 2250 fps with RL-7, 200GR corelokt, rem cases, CCI primer. I am above max but load is safe and accurate in my 336. If you lose your accuracy with the vel increase, it's not worth it!
Thank you Caveman
You answered my question consisely and to the point. If you routinely get 2250 fps from your +P loads then the fellow that I saw at the range who is getting 2275 - 2300 fps in his Marlin 336 is not so far overloaded. I know nothing about his loads or accuracy only that he said he used H-4895 powder.
Your information combined with his cases that I examined leads me to think that he was probably well under 50,00 psi. I was thinking that someone on this thread with a computer reloading program such as Quick Load may have an educated guess on max loads and pressures. The question is academic anyway, my 336 is in 30-30 cal. and I don't use +P in it.
Thanks again for a good response.
Jim
