Built my first one about a year ago to take hog hunting in South Carolina. It's a 16" with a Palmetto state upper and lower.
I ordered a 10" upper from DSG Arms during their Black Friday sale. Have the paperwork submitted and should have my stamp next week for it's own lower. Here it is on a lower I already have a stamp for
Around Christmas, I picked up a Ruger American Ranch in 300blk. Here it is with a titanium solvent trap attached. I should have my form 1 stamp back for it in about two weeks. When I get the stamp, I will drill out the end cap and form the baffles to make it an 8" suppressor.
The solvent trap
I plan on running the suppressor on the Ruger and 10" upper. I will probably end up submitting for another stamp and build a shorter (6 inch) can for the 10" upper.
So far, my loads consist of two cast bullets, 230gr and 155gr from Lee molds, 125gr Nosler Ballistic Tips, 147gr FMJs and 110gr Barnes Tac-TX bullets. The Barns and Noslers are used for hunting and the others for Plinking.
I powder coat the 230gr bullets and will probably order another 155gr mold and mill out the gas check shank to make it a plain base bullet so I can fire it through the suppressor. I don't want to risk a gas check coming off in the suppressor. I casted, lubed, sized and gas checked about 1000 of the 155gr.'s before I started powder coating. All future casts will be powder coated.
For subsonic rounds (using the 230gr bullet), I've settled on 10.7gr of Accurate 1680 for the AR and 5.7gr. of Unique for the bolt action. Just took the Ruger to the range this morning using the Unique load. I probably will not mess with this load because it shoots good enough. Here is how it shot at 50 yards. I was checking for velocity and stability with that load. I fired 4 shots and had to fire the 5th a little off to the side to make sure the bullets stabilized before they were used in the suppressor.
This will be a very cheap subsonic plinking load considering that factory subsonic rounds are over $1 a round. With the Lee bullet, Unique powder and primers,I can load 1000 of them for $40-$50
