I was hoping for and suggested a 200gr WFNGC. The reasons being, one still gets good penetration, but more importantly, allows a standard Glock barrel rifling to stabilize the bullet.

Too heavy and this happens ( hickok45's video) :

Great video as usual from Hickok45.

However, someone needs to tell him that there's a big difference between hot 10mm and hot 44mag.

Same here. That said, I'm pretty impressed with the 200gr TMJ Speer rounds. They seem to hold together very well.

The standard Glock rifling is fine for heavy bullets. It's the poor fit and crappy tolerances of that 230gr bullet that Double Tap uses that's the problem. The same is true for any cast bullet, they just usually aren't that bad.

Gosh darn it! Now I've gotta save up for some 220 hardcast. Oh well i guess the 200 xtps, 135 noslers, and 165 gold dots will tide me over for now lol.

This is exciting ammo for the hunting 10mm enthusiasts.

The video is a good ole boy evaluation but cinder blocks are just too tough to cook. Even slow cooking doesn't tenderize them!

Using a G20, KKM 6" barrel, would the 220gr HC Underwood require more than the stock spring?

Require--no. Might eject better.

IMO, you should use the same spring weight you use for any other hot 10mm round.

Per an email I got from Underwood, all bullets stabilized perfectly through a stock barrel. Even so, do you guys think I could expect leading since the bullets are not gas-checked?

Great forums btw. Glad to finally be part of it!

I just need a starting point on spring weight. This is my first venture into hotter loaded 10mm until I start reloading.

I had assumed they were, but the email I received from Kevin at Underwood specifically stated that the bullets are NOT gas checked. That's what lead me to post the question about leading in the stock barrel.

This is exactly what i've been waiting for. Although i kind of expected a 200 grain bullet. The 220 is fine with me if it works well. That is interesting if it is truly not gas checked. Any idea when it can be ordered, or has anyone recieved any yet and shot it?

I sent Underwood an email last night after my post. Here is the reply i got early this morning.

My question is on item number 242. Is the hard cast bullet gas checked?
No, it is not.
If you have any other questions or need anything else, please let me know.
Thanks, Kevin

Merely guessing here, but they may be SNS casting hardcast 220gr. bullets. I have a number of these but I've never shot any out of the stock bbl and they're not gas checked either. I can't imagine they would lead terribly, but would expect them to lead some.

Underwoods TMJ 200 and 220 Hardcast are both "out of stock" I'll hold out for re-supply instead of buying DT's overpriced/underpowered offering. Until then my best bear round is the Underwood XTP sadly.

Handloading and casting are insurances to eliminate short falls and allows you to produce custom premium quality ammo and some savings over the long haul.
Good luck!

^^^ this ....

Everytime I hear someone post "gosh, now i gotta save for XXXX ammo" I just chuckle and think about my beloved Lee Classic Turret in my basement.

If you have the means to get setup for reloading ($300 or so up front), I'd HIGHLY recommend it.

Wanted to get some chronograph results and see how the Underwood 220gr hard cast works in a Glock 29.

I decided to compare the spread of hits of the 220gr HC between my 1911 with its Bar-Sto barrel and my third generation Glock 29. The G29 is standard, except for a metal recoil rod assembly with a standard 17lb recoil spring.

I placed the target at 30 yards and shot slow strings with my hands resting on a shooting bag. Took lots of time to make sure my sights were aligned consistently. Each square on the target is 1x1". The group in the upper left is from the Glock. The better centered group is from the 1911. Proves in my mind that the Glock barrel does stabilize the 220gr ammo. Then I shot the Glock at a distinguishable formation on a berm about 60 yards away, standing off-hand. The hits were comfortably close to the target, showing again, the bullets stabilize.

Here are the chronograph results

Altitude: 3221 ft, Temperature: 48 degrees, Barometric pressure: 26.9 inHg

Was one of these a cut and paste gone bad? They are exactly the same...(well except for your calculation of the average :D)

BTW I just got some of the 220 HC in the mail, it's back in stock (as of last week anyway).
