December $487 prefit group buy, several barrels are a go

[IrkedCitizen]

Where does a 20' 6PRC put you at 1800 fps, and what's the estimated barrel life?

Probably 10 miles with a 20 foot barrel

for 223 ai, 18” barrel. Loaded long. Middle of the road pressures should be close to:
80: 2800
88: 2725

That’s impressive… with the 88’s at 2725, it keeps above 1800 fps out to nearly 800 yards at 7800’ elevation 30 degrees. Here I was thinking I wanted to put together a 6cm/243 to shoot 95’s….

Take it with a healthy grain of salt. 88’s have proved very temperamental for most people trying to reload them. It will likely hit that velocity, but no guaranty that the groups will be tight enough to use. The 80’s and 75’s eldm have been very consistent and easy to load for in the barrel I got from LS with the 223 wylde throat.

Thanks for the heads up. Running the numbers on 80 at 2800, that puts it past 700 with 1800 fps. The wind bracket isn’t as good and it doesn’t lineup with quick drop too well. Still very tempting though…

Whats the advantage of UM 30 vs 40?

No fireforming with the 30⁰.
