Yes, .243 WSSM. It runs 100-200 fps faster than a .243 but the beauty is that it is capable of being ran in an AR-15 where the .243 cannot.
Browning/Winchester probably killed it when it was introduced in a bolt gun that had the standard feed ramps of a .243 causing a lot of difficulty when chambering a new round. Huge amount of keyboard "gun experts" before it came on the market calling it a barrel burner which it turned out not to be.
The AR feed ramps are a different angle and support the short fat cartridge.
I have two uppers, one in 1:12 for 55 grain bullets, and another in 1:8 for heavier bullets. Amazingly accurate at long ranges with their inherit limitations.
Smaller bullets are much faster with the .55 grain screaming at 4150 fps over a chrono and the 90 grain running 3400fps +/- a few fps.
I've killed deer at over 400 yards with both bullets. Currently going to try some of the 80 grain Barnes in the 1:8 to see if they stabilize and see how much additional fps can be added.
The short fat 6mm ARC has been introduced with much fanfare, but it can't compare to the WSSM in the same caliber.
Is that the gun that tried to set fire to the camo on the suppressor?
