Re: kinda off topic 9mm question

I guess if you don't mind a literal rainbow trajectory. You won't get anywhere near 900 FPS without having nuclear chamber pressures. 950 with a 158 gr. is fairly spicy. I think you'd be lucky to see 500 FPS without pressure signs. Remember, it's not just weight increasing resistance, but also bear...

kinda off topic 9mm question

So I was goofing around yesterday at lunch and decided to stuff one of my homemade cast bullets into a 9mm case just for kicks....then I got to playing with QL and was surprised of what I found. This monster 354gr bullet can actually get semi respectable speeds according to QL ~880-950 FT/sec from s...

Re: 30cal Integral Bolt Rifle Build UPDATE 4/25/2019

hmm. how about spinning up a new tube in 7.62x25 tokarev :D both different and more efficient for your purposes. I buy most of my bullets from here. shipping sucks unless you make a worthy order which is what I do a few times a year. http://www.shootersproshop.com/nosler-products/nosler-blemished-2n...

Re: 30cal Integral Bolt Rifle Build UPDATE 4/25/2019

Being a bolt gun and a suppressed one to boot wouldn't you want the fastest and least amount of powder to maximize or better yet minimize the amount of gasses needed to be cooled? Trail boss would fit the bill nicely and also fills up the case pretty well. Red dot is fairly bulky and would also work...

Re: Recore with clipped radial baffles

Nice! looking forward to what the 165 9mm brings. I take it xtreme bullets? been wanting to try them myself.

Have you tried K's before? That's my plan on my 9mm can as I don't have the tooling to cut radials. and I want to do a scratch build.

Re: 45 Cal Suppressor Design Review

some very cool designs. on the last design I would think it would work better if you went back to the spacer that sealed the vanes on the blast baffle then have that spacer ported in an angled helix pattern like ECCO's muzzle brake shown a few posts up. otherwise your blast chamber volume would be m...

Re: Starting a new can, titanium

You don't have to take heavy cuts if you use fresh, sharp carbide tooling. As I've mentioned before in ...

Re: Tube thickness questions

Use stainless for the tube and internals then weld it up. Or do a tubeless design. You could go thinner by using stainless if weight is a issue. There is a thread here somewhere of a members first build if I am not mistaken, he used 4130 for the tube and welded it. It has survived many years and he...

I have been always looking for the final distributor of these, but never found. My partner owns a CNC machining workshop. I helped to turn the designs into CAD drawings and had them machined. Why would you care if you made your money? something smells a little fishy. Probing for problems :roll:

Re: I need help with a form 1 question on the blast chamber

I think you'll find that most of us here build our own. The maglight (b,c,d) tubes aren't very common. the 24 tpi options from diversified machine and the like are a better suited to most builds. I could be wrong but the main reason you won't see direct thread adapters like that here is why not run ...

I'm a rookie myself but I want to say most people run .250-.280" I've also seen some do small to large on the apertures (closer to the muzzle tighter and larger towards the endcap. .090 is way overkill on thickness as is 1.230" OD most people run 1" OD 5-6" long for rimfire suppressors. with .070" b...
