Best 2 powders for 123 gr SST 18 in barrel

[Roland]

I'm new to reloading this cartridge. 35 years reloading others. Looking for mid to upper speeds with good hunting accuracy (1 moa)

[Zeneffect]

Cfe223 or leverevolution

[mdram]

8208 and arcomp are working for me, speed goes to arcomp

[Rosecrans1]

What mdram sez..........
xbr can spike very quickly when searching for speed.
cfe and leverRev are not real temp stable but certainly do make things go fast!!!!
In another not very temperature stable powder, PowerPro Varmint comes to mind.

Can't narrow it down to 2,
H4895, TAC and MR-2000 all work well for me

AA 2520 is also my most accurate powder with my 18" barrel and 123 SST's

I have a great load with H335 going to try cfe223 this summer with Barns 127 LRX in my 18" PSA .

Thanks guys. This gives me some ideas. I have some H335 and scored 2# leverevolution yesterday at the last.

Shooter's World Match Rifle for me. I had temp related pressure spikes with CFE 223 and 8208 was a non starter in my CZ.~ Riuma

The best 2 powders are the 2 that you have. If you dont have any, then the 2 you can find are the best.

[Klem]

8208 for projectiles below 120
4895 for 120 and above.

For a 19" barrel.

Speed will be whatever you load into the case.

Looks like eleven best two powders.

Looks like eleven best two powders.

Tac and Benchmark are missing.
