Tungsten Hammer over 800mm barrel and power block?

[Al_Miller]

I have a internally stock M3 (no slug power kit and no power block) only a nsa pin probe as the only hardware change. .25 cal 700mm barrel 40gr slugs at 940fps reg 150 and hammer maxed out. How much fps would just the tungsten hammer gain me? It seems like the cheapest upgrade of the 3 with the potential for the biggest gain. Also would it hurt me if I wanted to lower the power settings and shoot pellets if I wanted to?

I don’t want the added length of the 800mm barrel (700mm is the max I want for the hunting I do) and I don’t think the power block gives much of fps increase. Plus it’s more expensive and a more difficult install.

I'm interested in this as well. I absolutely will not buy anything longer than a 500mm for my m3 .25. I like the maneuverability.

likely nothing, truthfully you’ll probably over hammer the valve and cause valve lock or experience hammer bounce. In either case your speed will drop.

I installed a tungsten and a 800 mm had 25 cal pushing 44 gr h&n at 1022 fps till I backed it done to about 980 so my friend could get a whole magazine of shots with a 580

Barrel would probably help the most with the least amount of work. It would add 4" to the barrel tho.
