.224 build advice needed (in progress)

yah, iam gonna make a shroud and barrel band at the same time. i am stoked about the same hole 55 grains on the far left though.

i have yet to test the 47 grains. also ordered a tube to make it longer for more plenum.

Another documentation. dont mind me guys

i have gotten the gun to shoot 55.6grains max at 881FPS  for 96 FPE at 2800psi. i think can getting closer to 100FPE if i bump the regulator pressure to 3000psi or more. i will never build anything with shorter than 29" barrels anymore lol.

With 1.5mm stem vent hole. this thing is ultra adjustable! and with a shortened spring, i can tune on the cliff just as easily with the oem hammer. i can go from 750fps to 880fps with the 55 grains. and the 47 grains maxed out at 956fps. i am guessing i will get a couple of more shots from 23. I am liking it.

still havent been able to go to the range, but i am piling up 55 grains 47 grains and 39 grains. currently tuned at 89 fpe. i think thats good enough if the 55grains can touch something at 50yard and the 47 grains touching something at 100 yards.
