What's your barrel length? 24" I forget how many fps is lost per inch, but I'll be dropping a few at 20" plus the gas powered issue will suck a few fps.
The 123's at 2770 fps muzzle are still good for supersonic at 1000 yards, so if I push a little harder to ~2850 fps +-, should be in more than good enough shape. Eyeballing the primers and judging by the felt recoil, looks like the load is relatively mild.
Your speeds with the varget and 123g seem slow out of 24" barrel.
Im shooting 130-140fps faster than you out of 2" less barrel with only .9g more powder. I wouldnt think .9g more powder would be THAT much of an increase.
My load in your 24" barrel would, in theory be going 2950 or so(25fps per inch, supposedly), which is almost 200fps faster than your load.
After we loaded and loaded and loaded and found massive lot to lot variations. So you really can’t compare one lot to another. Lotta factors. Sometime they are dead on sometimes you lose 100fps in lots.

Exactly. I hate to even post load data anymore after the last few chrono tests we've run.

PB- you mentioned mixing 8's(?) of powder.
How sophisticated to you get with mixing, or is it a "dump in a 5 gal. bucket and stir" deal?
I have 3-8's of RL16 I'd like to combine and do load workup once.
Yeah.... last time I bought a plastic tub to blend a bunch of Varget. The amount of 4350 will work in a bucket. It's a pain in the ass, but lot changes have eaten my ass alive in the past, and I never knew it was killing me.

Same.
I did notice the RL16 had a substantial (for long range) difference in velocity- lot to lot.
Never "mixed" before, but I pictured; "dump in CLEAN bucket/tub (plastic), stir thoroughly, pour back in 8# containers".
I'm in.
Thanks.
