Has anyone had any luck reloading the 123 grain SST with H4350?
You can, but I think varget would be a better powder for that weight bullet
H4350 will give 50-60 fps more speed than Varget. Can't say if it would be more accurate, but H4350 is pretty much the go-to powder for 6.5's. I've never fooled with anything lighter than 140's so I can't comment on the 123's specifically
Have you heard of the secret Carolina load
140 gr class Bullets
I know the 140’s are very accurate I was just considering the 123’s for possibly a deer hunting round I just got into the 6.5 creedmoor as of right now all I have shot is paper. I been using superformance but I been seeing where a lot of guys say that H4350 was their go to powder
I shot the 120 SMK with Varget and they shot very well. Should have probably stayed with it but I wanted a heavier bullet and moved to the 140 ELD.
What about superformance and the 143 g eldx
Or use H4350 with it also?
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 better
H4350 was about 100fps slower with similar accuracy.
Rl-17 is also a good powder for the 6.5cm and 140 class projectiles.
With the 123s sup turned in bout 3k, and h4350 got 2850ish, accuracy wasn't great in the one rifle I tried it with.
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
That was a 143 gr eldx not an sst but no I haven’t heard of that I haven’t ever tried any of the H4831sc yet
Ok this is going to drive me nuts what is Ttrl?
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!
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).
