Crosman 362 .177 project

I'd be totally happy with that level of accuracy.
Especially considering it's a new Crosman barrel.
You must be very proud of your new baby...LOL

I couldn't be happier . This was a fun project.

So this brass valve half will fit the 362..
Will any of the 13xx 760 brass rear also work ?
I'd like to do all brass in my 362 FT build.

Give Tack Driver 10 a shout. He could answer that question. The valve in this 367 project is a custom made brass valve that he made specifically in the 13xx/362 format. The 1377 in my profile pic does have a hybrid 13xx/760 valve, and I know it has the 760 front half. I think all he had to do was add the hole for the front trigger screw, but he could he can answer your question accurately.

Thinking as much as I like the idea is it worth messing with vs the stock 362 aluminum valve ?
I will need to make it flat top and smooth the port, but past that I don't think it would be worth doing unless the brass would last longer from stem wear or something  ?
I'll shoot him a pm just to see.
But love the speed you are getting, like having a 22-250 in firearms.

Think of doing something like a clay block test. That would be interesting for it.

I originally had an aluminum FT valve planned for this build. I had it set up as low volume with a lighter spring. I never got to test it. Once Ron told me he was sending me the brass one, it was the obvious choice. From my understanding, brass has less expansion, does not heat up as quickly, and less friction wear. I am sure there are other advantages using Brass versus aluminum.

Yes, the FPS results for this build was a very nice but total surprise. The gains between pumps are incredible. Ron was right in an earlier post about squeezing out a little more by using an MROD valve stem. My goal was 500 FPS with 2 pumps and that would probably have done the trick. To be honest though, 485 in two pumps was close enough. I sighted it in at 3 pumps and I stick with that.
