The customs are shooting well in access of 2,300fps. With my custom 45cal, I send a 350gr XLD at 3,000fps when shooting SML.Some of the new custom or semi custom MLs are amazing. If I recall correctly, they were shooting 327g tipped bullets at 2,300+ FPS. I'm also certain they are very expensive to feed with teeth rattling recoil. I seem to recall a video or write up of a 300yd shot where there was no evidence of expansion. The same manufacturer bragged about 600yd kills with the aid of precision dialing scopes/ballistic programs. I contemplated this route and concluded the added range for where and how I hunt wasn't justified. I love ML hunting…and the excuse to tinker and experiment. This didn't seem worth the effort/cost. Just my 0.02.
We just finished shooting 5 relays at 1,000yds at Camp Atterbury, however there we are limited on propellant to 120grs VOLUME of BH209. No SML. I took 1st in the inaugural, 2nd last June and 3rd two weeks ago.
Recoil is very easy, as customs have muzzle brakes.
I target shoot, but I also hunt exclusively with a muzzleloader.
