Any ideas how to enlarge the transfer port forwards in the breech? Normal drilling will expand it to both directions and that would mean trouble with the barrel to transfer port alignment as I can't really move the barrel backwards any more.
Nice results and impressive power curve. Pretty decent for such a handy carbine. Whose 94 grain bullet is that please? I've got some 90 grains coming in that I'm looking forward to trying out too. First I might try to align my ports as you've demonstrated.Have you ever tried the lighter Korean "9mm" pellets? I think they are about 58 grain. I have some tins, but all the writing is in Korean. I've heard some people trash them - but I've also seen others with better results in accuracy. Any issues might be fixable with sorting and a sizing tool to match those pellets properly to the Rainstorm bore. I think of those pellets for you because they might allow you to back off the pre-load completely (or even swap in a slightly lighter spring) and still get some very flat (high-900s) shooting for your silhouette - for a good two magazines with low-enough ES.
Thanks, I have a better visual of the silhouette shooting now. Sounds like you'll have huge fun with that. A 9-inch Neil Clague LDC also takes that noise right down. (It does for the .357 Rainstorm). It overlaps several inches of the shroud, so the net length increase is less. A healthy thump, but definitely no more ringing ears in the garage, or need for ear protection.Nice looking de-pinger. How did you make it? Interesting that you would de-ping this, with the relative decibel level of the .357, even with an LDC. On a .22 Rainstorm with a Neil Clague LDC - all you hear is a ping. It's actually stunningly effective. But what are your thoughts about installing it in this gun?
I was talking to Will Piatt the other day just before he was sending me back my .25 StormPup and he's waiting for some new machinery for doing exactly this, get the Rainstorm .357 tuned to highier power, the future is bright He's strating to look into turning TJ .250 barrels to install on the Rainstorms .25 and be a ble to shoot cast bullets and those are probably easily tuned to 100 FPE that way.He's gonna keep me posted on developments and I'll let all you know when it's happening
