10mm resurgence

And yes, I agree. That's a key point for your decission.

I started with 10mm on a Sig P220, so the barrel length is 5". Plenty to take advantage of 10mm. So for me a short barrel made sense to add in. For an outdoorsy guy like you with black bears a foot, a G20 or equivalent is probably a better choice.

 

I think it's true for any cartridge with a shorter relative.

 

I have been Concealed carrying a 10mm for the last 5 years, but it is a full size Glock 20.

I have zero interest in a compact or sub compact in any caliber.

 

As I mentioned in an earlier post. You will lose velocity with a shorter barrel. I have a 2" 357mag yes I am giving up energy, but it still has more oomph than 38 special, 9mm, 40sw, and others.

 

Yep!

 

For my G29, I did drop down bullet weight to 165gr bonded jhp offered by Underwood. I don't have a crono, but they certainly are peppy. Also this is primarily for CC, so mitigation of over penetration and dumping all the of the energy into the intended target is my goal.

In my full size guns for outdoor use, 180 for walking around/general use. I was hoping to get a deer this year with some 200gr or 220gr hardcast.

I dont reload, I am not an expert. About the only thing I do, is research whether the advertised velocity is close to actual velocity and avoid paying for what is essentially overpriced .40.

 

Oh and beware of @460Shooter

He is an enabler. When I was just flirting with 10mm, he provided valuable information and followed up with pics of gorgeous firearms. My wallet has gotten much lighter due to his posts! (But he never steered me wrong)

 

LOL!

 

Any accuracy issues with the 220 over 200gr Hardcast? I have been told by several people that the 220s are not as stable as the 200s (both Underwood), but not had any issues using them in my G20, but I only use them when walking the fence lines where I might cross paths with just about anything.

 

In watching different YouTube videos as part of my research in determining which 10mm to purchase. They have said that 220 grain hardcast loads are more finicky than the 200 grain. I'm glad to see that you can use either/both.

 

Heres the Underwood 220 hardcast out of my S&W 2.0 with a 4.6” barrel at 15 yards indoor

 

Probably nothing unless you need to penetrate a really thick hide.
I only carry mine loaded with hardcast when I am working on our property in east Texas piney woods. I will probably never encounter a bear, but a ticked off wild hog protecting her young is a real possibility, and I have personally seen a hog take a head shot and just get even more ticked off.
Thats why I refer to these loads as lipstick for a pig.

 

I can't comment. I don't shoot any 10mm's with polygonal riffing and have no need for bullet weights that heavy where I live.

I just picked up some 200 gr HSTs the other day to try out, but no 220s.

I do plan to load some 190 gr copper monolithics with a flat meplate in the near future. They are cnc machined by Cutting Edge bullets. I figure they will do the job nicely if needed on any angry milk jugs.

Honestly I always thought if I was going to press into the 220 or heavier bullet range I'd step up to a 44 magnum.

@tommy.duncan might be able to tell you better. He has far more 10mm experience than I do.

 

My current carry loads based on pistol:

G40 220 gr Underwood Hardcast (dedicated woods gun)
S&W MP 2.0 4.6” 200 gr Underwood JHP
G20 gets the same 200 gr Underwood load
Springfield XDM Elite 3.8” 165 gr Underwood GD JHP

I also have 180 gr XTP with a hefty load of 800X that I won’t hesitate to carry in either of the top 3 and am working up a Nosler 200 gr load to mimic the Underwood offering as well.

Also won’t hesitate to carry the 220 Hardcast in either of the top 3.

Underwood’s 200 gr Hardcast also shoots well so I would pick either, based on availability, for woods carry.

 

Thanks brother,

I have shot some 220g but it was more function testing then accuracy. I live in the DC area and my defense rounds need to stop small black bear and 2 legged critters.
I usually carry Underwood 180xtp, in more "urban" areas I carry 180g HST. I have never looked into extensive shooting of hardcast or 220 grain, maybe I will start testing.

I have lots of lead and molds just in case but haven't needed to yet, i guess I should before I need to.

 

Here’s the information on Underwood’s 220 gr pull downs.

Here’s that copper bullet I mentioned on the right. It’s next to a 200 gr hst in the middle. And there’s a 454 Casull there for size reference.

 

The S&B 180 JHP is a good, accurate, factory round, leaving my 6” barrel at 1200 fps.

The fired S&B brass gets the Barnes 155 grain Tac-XP hand loaded to 1400 fps. Less recoil than the 180’s.

I mention this because both loads have the same POI out to 50 yards. Which is often my goal.

 

Yeah I agree the 10mm AUTO is in full resurgence. FN just introduced their model 510. Comes with a 22+1 rd mag and a flushing-fitting 15+1 rd mag:

Interesting times for 10mm fans.

 

My first and only 10MM is a RIA 1911 with a full rail style frame.The extra steel out front makes it an easy gun to shoot as far as recoil goes.The cartridge itself seems to have some inherent accuracy.Several of my friends also have 10's and they all say the round shoots well in several different platforms.Two of them shoot Sig X10's and they do very well.I have a Leupold DPP on mine and 180 grain handloads loaded full power with AA9 will usually stay inside of 4 inches at 50 yards.I've deer hunted with it the past two seasons,but couldn't get the deer to cooperate.
One nice thing about the 10MM's comeback is the number of 40's that are up for sale for cheap prices.I just bought a Smith and Wesson M&P 40 Performance Center gun two or three weeks ago at the LGS for a song and didn't have to do a good job of singing it,and that pistol is impressive.It's very accurate and the ported barrel makes it feel like a hopped up 9MM.I bought 500 Hornady HAP's at 180 grains to shoot in my 10 for lighter practice loads and they shoot crazy good in the M&P.The manager at the LGS said the M&P I got was so cheap because the 40 is dead and the 10MM killed it.Thanks to the 10 killing the 40,I now have two Performance Center 40's in my safe and I'll love them forever and ever and I don't care how dead they are.

 

I just texted the manager of my LGS to get one on the way for me!!! FN 10mm goodness!! Woohoo!!

 

Okay, H&K please follow with a new a VP10 or a USP10!! Please!!!!
