Go with ARH. Springs hold up very well. Seals need sizing you can do it with a drill and sandpaper. I use a plastic water bottle cut to size to surround the spring to dampen shock. I used the heavy spring and am getting about 820 fps. Smooth just a thunk.

Less than 200 bucks in 177. Shoots hard, very accurate. I got a pretty nice stock. It will be my gun off choice for shooting bugs long distance. Airgun Revision has some deals..

I have been using these mags and they are very reliable. I get about zero jambs out of them. Some pellets just won't work like the polymags.

I've looked at manny chambers that appear to have no throat at all. I don't know what the ultimate degree would be. We will know more as custom jobs are finished and results reported. Keep us in the loop please when finished and you are satisfied ot not on your project. Many thanks.

I have some P M me

Both are pictures at the end of chamber beginning of throat. You can still see a small edge where the chamber ends and the throat begins. Reamer was used to clean up the chatter marks some then polished. In other words picture one is after a .177 reamer did the chamber, pic 2 is the No 1...

Should be tapered and polished some. This is after tapering before polishing. Used a No.1 1 in 48 taper reamer.

This is what our barrel looked like prior to tapering.

I noticed when I was shooting several slugs lately. The NSA slugs chambered harder. I think they may be a bit larger and a bit harder. There is one thousands difference between NSA .1755 and H&N .1745

The lead in our first attempt was 1 in 50 which is common with most taper reamers. I read though, a lead of 1 in 100 is preferred. I purchased some non hardened drill rod to make my own reamer then decided to go with the typical 1 in 50 degree. I think that could have been some of our initial...

Shooting 60 yards at that speed would be challenging. You will need to be spot on with your distance calculation. Polymags sure will work but I doubt they will deform much at distance.

Our goal was to shoot 17 to 20 grain slugs. We initially decided to try Redman barrel liners in .172 that have a 1- 9twist. WE just could not get the accuracy out of this barrel. Using NOE's sizing dies they did a good job at resizing but accuracy just didn't get much better that 1" at 50...

Well that is what Thadius told me Saturday on the phone, from Utah Air. He is also the one that confirmed twice 3 weeks ago the heavy was 1 in 16. Supposedly Utah is the main distributor now for FX. You would think they would get their product info straight. The STX Heavy in 700 mm will not...

Utah add states 1 in 24 twist for the 22 in standard STX and 1 in 16 on the heavy. No listing at all for the 177. My 177 heavy has 1 in 18 lasered on the barrel. When i was firing NSA 20.5 SLUGS I notised they were keyholing. Disappointed in the twist rate. 15 is as big as I can get in my...
