So I took the valve stem down to .090 and am running 36 gr at 989fps now and my hammer weight is only a 1/2 gram heavier I'm happy with that I'll have to shoot it and see if that is another accuracy node hopefully

I've done the same to a dynamic and used a impact tungsten hammer on it and it pushing 30 cal 54 gr slugs at 1040 ish faster if wanted but it's not needed it is definitely easier on the drs to change out a hammer weight tungsten hammer is about 2 grams heavier than the stock hammer

That's a dynamic but it is same valve so it should work wouldn't get a lot of shots at that power level.

I like to push it to the limits and then back off the adjustments a tad for better life of it and still out perform stock form if the speed works with accuracy otherwise I back it off farther just depends on the accuracy node

Well I've used my cast 36 gr slugs and they shoot pretty accurate if you cherry pick them meaning look threw for defects they are running 970 ish and h&n slugs 40 gr are a Lazer at 935 ish which I'm happy with

Im shooting 26 Gr slugs at 950 fps with the reg at 95 bar on my DRS ( slug power kit and Huma tunning spring installed ) hammer spring is almost flush too… I need heavier slugs now with this setup, gonna try 34 & 40 next. I also installed the CF sleeve over the liner. It seems to like low reg pressure. Shoot one hole groups ez.
