I've completed my 577 2 3/4" NE, below are some photos. Action is a Jana 10GA, with Greener Cross bolt, 24" Mono-Blocked Pac-Nor match grade barrels, 13.4 pounds. Load is 750 Grain bullet @ 1950 FPS for about 6500 FPE. Regulated at 50 yards, 1.5" composite group. Recoil is stout, not for children. Gun could easily handle the full 3" nitro load, and was proofed above those loads. Maybe the next build will be a 3" chambering.

PS: I should add, that I did a lot of tuning on the locks, new springs, pins, sear work. Also, stripped the wood, re-shaped the fore-stock, added and shaped the 1" Silvers Pad with Birds beak, stained and refinished the stock using Old English African finishing oil. Quarter rib, front sight, and ribs were made by me as well.
