I just purchased the Glock 40 MOS that Bill/Oregon had listed for sale. I'm planning to buy some heavy hunting ammo from Buffalo Bore, and am trying to decide between these two.....

220 gr. Outdoorsman Hard Cast

190 gr. Dangerous Game Mono-Metal

https://www.buffalobore.com/in...product_detail&p=571

I emailed Buffalo Bore, and according to them, the 190 gr. was a recent design and will do "everything the 220 gr. hard cast will do". I suspect it will do well....I'm just a little concerned about the meplat being substantially smaller than the 220's.

What are you guys' thoughts on the matter? Do you think the narrower meplat will result in less penetration? Or worse....a wound channel that isn't straight?

My experience says that the lighter monometal will penetrate more (less upset, higher velocity), but the wider meplat on the hard cast should penetrate straighter and with a wider wound channel. Both should work, I'd use the more accurate of the two.

Might want to try both in your gun. Some Glocks don't like the 220 gr. They would keyhole at 10 plus yards. That gun might love them.

Your mileage may vary.

I would try the lighter one in the 10MM. I have a 41 Mag but haven't killed anything with it yet so no bullet performance. I am pretty sure I have hard cast WFNs. We carried 185 gr HPs in G22s on duty for corrections transportation. Be Well, Packy.

Either one will do just fine.

Shoot and carry the one you like the best for what ever reason.

Buffalo bore and my hand loads 180's in my Glock 24 40S@W get 1130fps.

I carry 165s jhps for just normal every day.

They do not recommend (Glock Factory) shooting hard cast in their barrels. Something to do with the Polygonal rifling they come with. No idea about the issue??
If you had any concerns (wolf replacement barrels are relatively inexpensive).

The so called issue is/was one or two people let the lead build up in the barrels so bad.

That it raised the pressure levels to the point of failure.

I have shot many thousands of rounds of cast bullets in 9mm and 40S@W Glocks

With out issue I just make sure I clean the barrel after I shoot any cast bullets in them.

I don't think any manufacture out there warrantees any of their fire arms with/for reloads.

I have a 50 GI top on the other Block 21. Both barrels are conventional rifling and don't lead up for me.

Glock Polygonal rifling is far smoother than most conventional rifling. So smooth that one can not get any marks for ballistic comparison.

Glock offers a service to PD's to mark their barrels so they can find out what gun fired what bullet.

I idea that a smoother bore would lead faster is ridiculous.

I was not aware of their rifling V/S ball. comp. Admirable for Glock to help out the P.D. Admittedly, it was most likely for P.R., but, hey, take any help where you can get it.

The first dept. to ask for it was Miami Fl.

They had a shooting involving 5 or 6 officers.

Suspect only had a few bullets in him compared to the amount fired.

All the officers shot.

They could not match up who's bullets were in the suspects body and from who's gun.

So the story goes they asked Glock to mark the barrels.

At least that what I was told by the Glock Rep. and Glock armorer Instructor. At one of my Last Armorer classes.

When they told us that option was available.

Its new and your getting a lot of guess and by gosh, time will tell, I suggest you buy a couple of hundred of each and test them yourself, thats the only way you can answer your question and know which is best, let us know if you don't mind...

I came back to this. Ray has the ticket for success. Two hundred of each would be a statistically proper study it seems to me. Barrel and all will be better broken in. I don't think it is possible to break a Block that way. They ARE made to shoot and shoot. Be Well, Packy.

I gave up testing on my own.

Just check out you tube and you well find someone that has done it all ready.

I wanted to set my Glock 10mm up for hogs so I shot some 180 gr. hard cast bullets. They shot good at lower velocities but the faster I pushed them the worse they shot. Not so in my Kimber 1911 so i don't think it is the bullet. 200 gr. XTP bullets shoot well at max. velocity so that's what I went with. Only shot one small hog and it was just a finishing shot so no real experience yet. May just be my particular gun.

Buffalo Bore used to have info on their website about using a heavier spring in a stock Glock 20 for the 220 grain hard cast in a 10 mm. Stock barrel and heavier spring works well in my Glock 20. After-market barrels that several of my buds use have been spotty on reliability. Pretty popular combo up here in Alaska.

I handload a 200gr cast bullet that's powder coated over a near max charge of blue dot. The Glock seems to like that bullet as does my AR pistol and my Kimber.

I tried the Double Tap 220gr several years ago in my Kimber and I decided I prefer the 200gr. I bought a mold that is very close to the one they use for their loaded ammo.

I will probably get hammered for this but I see the 10MM as neither fish nor fowl..I prefer the 9mm or or the 45, and those years of being proven..but I am a curmudgeon, deal with it or not, thats my story and Im stick'en with it!

Ray, you just like the 45 ACP because the pistol they designed to shoot it was released on your birthday...1911 :-)

One could say the same about the 41mag.

Why when you have the .357 and the 44.

The 10 gives a useful velocity increase with in it's bullet weights.
