SENECA/Sumatra .20 .22 .25

These guns give about the same results as the Career 707. I tune for increased efficiency, less velocity spread while keeping or slightly increasing power. The Sumatra .25 long gun can be tuned to get a flat string for 6 shots using 52 gr. cast slugs at about 920 fps. Good for penetrating hog heads.

Full Tune includes disassembly, clean, and lube, power and consistency mods, trigger job with contact points stoned, polished, proprietary lube, and adjustment, power wheel increased adjustment mod, all new seals, upgraded spring assisted fill check valve, and chrony tested.

Full Tune $275 plus shipping.

Reseal only: Disassemble, clean, lube, and all new seals, new exhaust valve, and upgraded fill check, seat lapped as necessary. $175 plus shipping
