I've run both sup and h4350 behind 123s and 143s. Using sup loaded long I was hitting 2750-2850 with the 143s in 3 different 6.5cms. accuracy has been moa or betterWhat about superformance and the 143 g eldx
^^^thisHave you heard of the secret Carolina load
140 gr class Bullets
44.3 H4831sc
I've been operating under the hope that it means "Tagged To Read(maybe reply) Later" but I too would like to know for sure!Ok this is going to drive me nuts what is Ttrl?
Nosler Says 40.5 to 44.5 with accuracy around 42.5 for 2877 fps out of their barrel, I'm interested too as a 123 sst humming around 2800 out of a 20" tube sounds close to what I want my cm hunter build to perform at by this fall for either my kid or wife to run (whoever loses the fight over the cm will get the old standby .243 I can only afford to build so many at one time lol).View attachment 844831 I done a test of a few different loads and this was the best group other than the one I jerked to the left I knew as soon as I done it close to the max load but no over pressure sighns I might go up another .5 or full 1.0
