Piercision Rifles 7 Mega results

[Piercision Rifles]

Well I spun up a 7 Sherman Mega barrel for myself with the custom spec JGS reamer that came in. Switch barrel setup on my long action ANTIX rifle. My goal was to have a 180 berger at a mild 2850-2900 fps in my 22" benchmark while using N565. Didn't want to mess with N570 personally as I didn't want to be looking at 28 nosler barrel life. Should get 1000 rounds of very accurate performance out of this combo. Fireforming loads were very mild but would have cleaned a 600 yd fclass target with a high x count. Several 5 shot groups into 2" or less vertical. I used my compressed air line to cool the suppressor and barrel between each shot. Has several drying devices before the air hits the barrel. Once I got the barrel broke in I found an extremely wide node at 2880-2915 where they all hit the same spot on the target at 890 yds. Was 3" vertical for the powder charges in that zone with .2 gr increments. Fine tuned the powder charge and then tweaked the seating depth a hair and shes absolutely hammering. ES of 15 or less for 10-15 shots consistently. Had one 3 shot group under an inch at 890 yds and the last group I had shot at 100 was .155" for 3 shots. This load is mild enough that a piece of brass with over 10 firings on it still had a primer pocket that felt almost brand new. Brass should last 20+ firings no problem and not get clickers. Be hard to beat for anything I won't need my 300 NMI for. TBAC Magnus S RR makes spotting hits an absolute breeze. Hardly moves.

Ill have more 7 mega's available shortly. Sending a 24" one out to a buddy this week.

For guys Ive built rifles for already if you want a switch barrel set up I can mail you barrels chambered, threaded, cerakoted etc. Can do that in any cartridge you want as long as I have the reamer for it.

A 180 at those speeds will do anything you need it to do.

Yep. Figured a short compact suppressed setup like this is perfect. I have the TBAC Magnus K RR suppressors coming in a few weeks. Ill throw that one on since its 2" shorter and 2 oz lighter than the one in the pic. One in pic is the S version.
