That’s a 168, 169, and a 175.
I’ve had a chance to shoot these. Sierra has done well.
I’m using 44.4 grains of Varget and getting around 2,750.

I'm curious to see if these are transonic stable. Have you shot them past 1k?
2750 out of a 20” barrel? Not bad.
I’m running 45.3g Varget with virgin Lapua brass and getting around 2650 over a Federal 210M primer.

24” barrel. That 20” note refers to a different barrel.
I was also checking return to zero for different AI barrels.

Unsubstantiated rumor. I called the ballisticians and Sierra cannot recommend any COL that’s outside the SAAMI spec for the cartridge.
Got a box of 500 of these. Gonna do some reloads soon. I’m gonna try it with CFE223. See how much speed I can get. I’ll be using Peterson srp cases and CCI 450. Shooting it out of a 26” 10 twist AXSA. We see how it performs pass 1k.
It'll be interesting to see yours compares to the CFE223 I had. I haven't use this powder for my 169 SMK's, but this is how I estimate my CFE223 would perform with them the way I tend load them:

This was shot prone w/sling from my M40A1 clone at Reade Range in western Pa. Temperature was around 45* and elevation is approximately 1400 feet. Sighter #1 was shot with a different load, sighter #2 and shots 1-6 were shot with IMR 4895. Shooting was done for load test only, not score. Shot number 6 was the result of a wind speed increase of about 2-3 mph.

Bob,
The grid squares on the shotmarker target are 1 moa or 10". I figure the ammo was good for 1/2 moa considering I was shooting prone/sling and heartbeat makes crosshairs bounce a bit and usually only in the vertical axis. Another side note, the barrel is a Kreiger SS 5R 1-11.25 twist. If you want the load PM me and I'll tell you.
