200 pieces of 1x fired brass tumbled,sized,the works and separated by headstamp.100 pieces of LC brass processed,weighed,etc and loaded with my mk262 mod1 clone recipe. 100 more pieces ready to be filled with my mod0 recipe. Looking forward to the day i can get my hands on some TMK projectiles to play around with to add the the logbook.
Curious what your mk262 clone recipes are?
18" 416r stainless 1-7 wylde barrel rifle length gas(port opened up to .105) Please use caution and work up your on load for safety reasons Mod0 1.LC,PMC or Wolf gold brass 2.CCI 450 3.COAL 2.258" 4.Accurate 2520 (24gr gets me 2597fps and .490" groups) (* above max charge in some manuals.no pressure signs in 18" rifle and 24.5gr gets me 2680fps and .468" at 100) (*ejector swipes started showing on 16" so i stopped here as it shoots good in all my ar platforms. from short to long and I'm confident to ring steel or vermin at 600 and would try at longer yardage with more practice.
Mod1 1.LC,PMC pr Wolf gold brass 2.CCI 450 3.COAL 2.252" 4.Accurate 2520 (24gr gets me 2618fps and groups of .530") (24.5 gets me 2707fps and groups of .549") I set the bullet deeper as the groups were larger if set at the mod0 length. Never went back to check on any different charges to see if groups would tighten up with a lower charge on the smk with cannelure. With all that said once i get some tmk's I'll dabble a little more in the 77grainers. And just maybe prices will come down to.
I thought that might have 2520 in the load. I’ve heard of guys getting around the 2750fps as the load in the 18” barrel with 77 smk. That’s really pushing things though. I watched some of JRB do his mk262 clone trials. If this powder situation ever improves, I’m gonna grab some 2520. Did the other brass hold up as well as the LC brass? Either way .549” @2707 is one hell of a load.
