I switched to them out of my 300 WM last year. I only shot a deer with it, but worked well.
I tried a lot of loads and lengths with H-1000, but could barely get to a MOA. Switched to Retumbo and got much better accuracy and a lot more flexibility on lengths and charge.
You can replace the Boss with a conventional recoil replacement to quiet it down The Boss system still works with it. I did it, and it's cheaper than cutting and recrowning. The downside it that it's still about 4" long.
How about not having a stormwater polution protection plan (SWPPP)? I don't believe they filed one and I didn't see any BMPs in any of the pictures I've seen. That brings DEQ in.....
