10 MM

YugoRPK · Post by **YugoRPK** » Mon Feb 16, 2015 9:21 am

Picked up a Glock 20 the other day with extended LWD slide and 5.75" threaded barrel. I know even the tamest 10mm will go supersonic out of that barrel but I figure I can load up some 220 grain heavy bullets at around 900 fps that will still pack a wallup. Threading on barrel is .578 so I can use a 45 can. What would be the quiesyest can for this project?

Any of the modern 45 cans could handle 10mm just fine. Just don't expect anything "quiet."

Silence is relative with a silencer.

The aluminum cased Blazer ammo uses a 200gr bullet;
per the website its muzzle velocity is 1050fps from a five inch barrel.

I am picking up a G20 10mm soon, I plan to buy all of the conversion barrel for it, all threaded of course. 10mm 40s&w 357sig. All can be suppressed. Most cans can support this ammo. Also most 10mm is loaded to .40 spec or even just above.
Personally I think the best 10mm ammo is Underwood.
10 and 40 will do ok.
357 and 9x25dillon both break the sound barrier, but the suppressor will take the edge off.
I plan to do the same thing!

I load my own 10mm so I'm not terribly concerned with 10 mm ammo availability . I do have a couple of hundred rounds of the Underwood 155 grain loadings . I will not normally use them in my Glock 29 though with the factory barrel as it WILL blow primers and rupture cases gauranteed. Had it out the other day and a full 20% of the cases of the 10 I had in the mag ruptured before Iswitched to sane loads. I have a longer 10mm barrel from LWD and the brass comes out looking excellent from it but the factory Glock barrel is a disaster with the hot loads. I will say that with the Glock 3.76" barrel I can regularly shoot 1 1/4" groups at 15 yards off hand with PMC ammo even with the stock 5 1/2 lb disconnector and stock sights which frankly amazes me..

I recall reading some time ago about how some police departments were moving away from the GLOCK 21 since it didn't fully support the case. Apparently they were finding a lot of brass with bulging, although I don't recall any ruptures being reported.

Are you saying that LWD has more support for brass than OEM? And if so, are you seeing any decrease in reliability for the LWD versus OEM? An increase in FTFs, for example?

The glock barrel definitely does not support the case at the base . Moderate loads are fine with it but hot loads absolutely do bulge the brass. I consider brass fired through the stock barrel to be trash if its fired with a hot charge. The LWD barrel is fully supportive and quite a bit tighter in the chamber.

I have never had any ftf or stove pipe or really any other malfunction with the stock or LWD 4.6 inch barrel. I run both with a 22 lb spring.

Sorry about being OT Yugo, but what is the Bridgeport hanging on?

That's OK. Actually that's not a BP. It's a 225 promax 2.5 liter on the back of an '81 checkmate enticer I restored a few years ago. I've got an Allison XB2003 with a steroided up 225 pmax that's taking up all my time and money these days. Had it out over the weekend running 94 MPH with it. Fun ride.

Sweet. I had a Bullet with a 225 Pro XS that I never had the balls to top end.

YugoRPK · Post by **YugoRPK** » Tue Feb 24, 2015 1:19 pm

With the Allison its just a balancing act. Ive got it set up for starboard side driver seating so I have to lean to the center to get it to balance on the pad at high speeds. With a passenger its a lot easier. Still runs 94 MPH with a passenger and fishing gear which aint too shabby. Fresh "99 225 promax with Brucato SVS and ACU and 150 lbs compression. Easy 260 HP at the prop.

Nice Boat

My choices given what you have said are Silencerco Octane or AAC TiRant

RJT · Post by **RJT** » Tue Feb 24, 2015 4:11 pm

Very nice. I never bothered to set mine up right, just ran it the way the previous owner had it. I always chickened out when chine walk really set in, just couldn't seem to drive through it. It was definitely way too much boat for me, but it was fun.

Is the Tirant rated for full house 10mm?

YugoRPK · Post by **YugoRPK** » Wed Feb 25, 2015 3:06 pm

I wouldn't shoot full power 10mm nor would I expect a can to live through it

No, it is not. Do not shoot 10 mm through one. The Osprey 45 is rated for 10mm, but the Osprey 40 is not.

Thanks. I believe the octane 45 is also rated for 10mm. Anyone know about the Revolution 45? It uses aluminum baffles so I assume it's not, but thought I would bring it up.

T-Rex · Post by **T-Rex** » Thu Feb 26, 2015 8:38 am

I know the Octane 45 is rated for 44Mag, told to me by SWR, but that is out of a 16" bbl.

YugoRPK · Post by **YugoRPK** » Fri Mar 06, 2015 8:30 pm

I decided on the 45 TiRant. Called up my dealer to check prices and he hooked me up with one for under $500. Sweet! Now the fun part.

NickAAC · Post by **NickAAC** » Fri Mar 06, 2015 8:35 pm

I should probably jump in here. 10mm should never be fired through a Tirant 45. It was not designed for it. 10mm is a great round, but is absolutely horrible for silencer use.

YugoRPK · Post by **YugoRPK** » Fri Mar 06, 2015 8:54 pm

Once again . i have absolutely no intention for firing full power 10mm through the thing. 950 FPS 200 grain loads yes but not 1500 FPS 155 grain loads. More than likely I'll just pick up a 45 top end for the Glock. The tax man was very good to me after unloading some depreciated rental property last year

Screw it. Just bought a factory threaded barrel 45 Glock to go along with the TiRant

Went out shooting with the G20 yesterday. Extended tacticallength slide with 5 3/4" threaded barrel and 3.5 disconnector. Handloads with 10 grains of Power pistol using 165 grain plated HP bullets. Pretty stout load. Didnt bring the chrono but probably 1400 ish FPS. They did have a little snap t them but no over pressure signs. At 40 yards I was getting a bit over 2 inch groups off hand. I was handily making a tin can dance around at 50 yards. Very impressive accuracy.
