I can hit pop cans all day long with 9th highpoint and a scope or good red dot at 100 yards.

Mine isnt quite that accurate, i miss every now and then. With the cheap blaster loads it shoots 5-8" or so, and with the hollow points it carries for general use it easily holds 3-4" at 100yds. One random box of winchester cheapo fmjs shot inside of 1.5" at 50yds, but the rest ive tried havnt done so well. could just be I need to tighten up my gun again.
My buddies 9 (which he bought after i got mine), shoots 3-4" groups at 50 yards with everything weve fed it so far. Im gonna take his gun apart and see if something isnt kinda loose there also, as i honestly expected it to be better.


OH!, one thing thats really nice about Hi-point is that they stand behind their products. I called to order replacement springs, and a new firing pin as i bent mine when the bolt slipped while reinstalling it.
They asked for my serial, and sent two sets of replacment mainsprings, and firing ping/springs for free.
It did take me 2 weeks to get ahold of anyone on the phone, as by the time i take my first break at work here in hawaii its 2-3 on the east coast.
 
I hate to be the naysayer here, but handloaders expecting to get the same long barrel velocity gains out of a semi-auto pistol cartridge that you can get out of a revolver cartridge are probably going to be a bit disappointed. The reason you can make a .357 mag or .44 mag scream from a long gun is that there are loads for them using slow burning powers like H-Lil'Gun, H-110, and ACC#9. As far as I know, there are no auto pistol loads for those powders.

Not that the 10mm is exactly weak tea, but it's probably never going to gain that much velocity in a long gun.
 
I've loaded 180 Speer Gold Dots over a case full of Blue Dot powder. They scream out of a G20 and they are within pressure limits. 1,250-1,300 fps IIRC. No detectable bulge of the case. They should do better from a rifle.

You mean like the load data for 10mm using AA#9? It's an excellent powder in that application.

true enough, but of all the auto pistol cartridges it has enough case volume to give a decent increase.... :)
 
If its anything like the other hi points ive shot groups should run 2-5" or better at 50yds.....im interested to see how it all works out. While i dont think its doable as a blowback .460 rowland (or equivalent) would be even more interesting. As it stands a 10mm would be a definite step over the 9 and 45s that are popular for pig control here.
Yea I've seen it debated a few places if it's safe to ream the 45acp chamber out to 460 I have a mechtec 460 it's a blast. If you could ream the 45 that would make a pretty cheap toy. If the 10mm is a reamed 40 I'd say the 460 is a go.
 

I owned the 1911 version about 20 years ago. Bought it on eBay. Sold it on eBay. WAAYYY too heavy compared to a Hi Point or Marlin Camp Carbine. The Glock version might be better, but I would really rather have something like the Ruger carbine or the Marlin. The trigger safety on a Glock might be OK for a holstered gun, but I don't love it for a rifle where the trigger's just hanging out there for every limb, finger and zipper pull to snag.
 
I’m curious as to how the 10mm will differ from the other calibers. The blowback action seems like a bit of a stretch for real 10mm loads

And when I say real I mean not the big three loads which are merely 40 in a longer case.
 
Moving from a 4 inch to an 18 inch barrel in a 10mm gets you about another 20% of velocity. (A little less for some loads, a little larger for some loads). The biggest increase is in light bullet high velocity loads.

.357s fare a bit better with about 25-30% velocity increases.

http://www.ballisticsbytheinch.com/357mag.html

It is of some note that the lighter bullets in 10mm, (the 135s) have about the same increase ast he 135s in the .357s. Its the fact that the .357 loads top out at the 158 grain and the 10mm loads push into the 180-200s that is the difference.

I still want one. 25% more of 180 grain, velocity, is a better proposition than 25% more of 158 grain.

For factory ammo, IIRC Federal makes a 180 gr cast load, rated 1550 ft/sec in 20" barrel.

Ballistics by the Inch clocked the 180 gr Buffalo Bore 10 mm at 1573 ft/sec in their 18" barrel. However, Buffalo Bore advertises their 180 gr .357 Mag to reach 1,851 ft/sec from an 18.5" Marlin 1894.
 
I know that there are AR based 9mm carbines that have met with mixed reviews... any chance that a 10 is a possibility or are the size of the cartridge and round just too big for something like that?

Those also exist, but the ones I have found are a bit pricey. You could buy a few Hi Point carbines with upgraded stocks for that kind of money and the carbine are darn near bulletproof.

My bear load is a 200 bullet with 13 grains of AA#9. It gives me 1200 fps out of a Glock 20 or S&W 1006. I would be quite curious to see how much of a gain a 16” barrel would provide.

powder type plays a big part here - slow burning powders will gain the most AND in some cases fast burning will peak out too soon and POSSIBLY cause a reduction.....
