Have been trying to choose between two FX rifles, now a practical third choice

[Roachcreek]

I have reached out to Pyramydair to see if they will sell me a Crown VP with the Superior liner.



I have no clue on What the response will be.

I am shooting a mold I had Arsenal custom make for me, it is a 58 grain swc dropping at .252 cast of 40-1. The intent was for a heavier slug in the .25 Seneca 2500 carbine, in which I am getting 85 FPE in that little unmodded carbine.



Would the Crown have the lungs to deal with it sized down to .250, if that is what the groove diameter turns out to be.

That is hefty. I would not expect the crown to shoot those fast at all. Not without adding some plenum volume (easier said than done) , and opening the valve up (valve seat is 5.5mm) factory hammer without adding weight stops being effective at opening the valve much past 135 bar. I use a 7gm weight for 150bar. Which gets me 870fps in a 700mm 22 cal barrel with 36gr slugs.

FX are not set up to shoot heavy slugs without extensive work from valve, to plenum, to hammer weight, to regulated pressure limitations...



Can it be done with an FX? Sure? Do I advise it? No. Even more so if you find the impact too much for you...



Just my 2c

We’ll Arsenal molds are 90 bucks, I can always cast a lighter bullet. I pretty much want it out of the box ready. Still not sure whether 25 or 30, but being as they are all out of stock, I am in no hurry.

Thanks,
