Trailboss is quiet!

It isn't ideal, but it does work. I started with 6.5 grains under a 90 XTP, and worked my way down to 5 grains. I would seat the bullet deeper to take up some of the case capacity for better consistency, but that's as deep as my seating stem will go! Velocities aren't very consistent. Last 5 shot string was 1094-1135 with the average at 1106. I think 4.8 grains will work, but will probably be even less consistent. A 125 boat-tail like the NBT would take up some more capacity and probably work better. With the gas port closed, this load is VERY quiet in my AR, and the last 4 shot group (I forgot to hold over on the first shot) at 100 yards was about 1.5". These bullets are made to expand at this velocity, and this will be my backyard pest control round:

What grain bullet is that ?

[Titleiiredneck]

90gr xtp, cute little booger.

was that made for a 32acp?

30 carbine or 762x25 would be my guess

Those are very interesting indeed! I replaced a handful of WOLF 7.62x39 fmj bullets with some 32acp bullets I had collecting dust for S&G's in the past.

Please keep us updated on your results and any further developments. I think I'll add some of the XTP's to my next order and see what the x39 can do with them at full throttle.

they look like they would make fun& cheap shooting

I just ordered some to try...looks worth the effort...

That load of 4.8 grains Trailboss under the XTP is incredibly quiet, I shot some more of them this past weekend. They do not feed from a magazine though. I think it's because the OAL is too short, and the HP just deforms if it gets slammed into the feed ramps. I have to push them into the chamber with my finger. I put a picture in another thread, but I guess I'll add it here too:



That one was run at 1900 fps into gallon water jugs. It blew up the first one, and stayed inside the second one. I haven't shot a water jug at subsonic velocities yet, but I think they will expand quite nicely. Someone should try it when you get some in.

Any quickload users that would like to offer some other powder options for full speed fun?
I wonder if this will feed OK in my single shot?
