Are DoubleTap 10mm 230gr Hardcast safe to use with stock Glock barrels?

These rounds are sweet:

http://www.doubletapammo.com/php/cat...roducts_id=158

But, are they safe in stock Glocks? I called the company, and they said there were safe - because of some special coating applied to bullets (??).

But, what do you all think? Anyone tried these in stock Glocks?

Not sure about any special coatings, but many have shot this round in the past from their Glocks. You could experience failures to feed, due to the large wide nose shape, however, if I recall DT was seating those shorter, @ 1.2420". Some of those heavy weight bullets were gas checked to prevent leading issues. I shoot cast bullets from my G-29 on a regular basis, just check for leading build up if any, clean up and inspect to see if bore and chamber are clean afterwards.

They should be safe but keep in mind they are upper end performance cartridges and as such they can run the slide velocities higher than other less potent ammo. Also collect some brass to inspect for bulged brass or worst "SMILED" cases...

They should be safe, but they might not be accurate. The problem with shooting lead is that it might not fit your barrel properly. That can cause the bullet to not spin and stabilize properly. If you do a quick youtube search for a 10mm hardcast video by Hickock45 he demonstrates this with the 230 grain DT WFNGC load in a Glock 20.

I personally handload their 200 grain variant. It works great in my G20 barrel. I personally think it is a better weight for 10mm.

EDIT: Found the video:

Yep. The 200 grainers work pretty well. Granted, mine are handloaded just like I want them. I have not tried McNett's factory loaded variants though.

I still have my fingers. I did experience some key holing out of a stock 29 barrel. YMMV.

I recommend buying 10mm ammo someplace else. Doubletap's 10mm ammo has been proven time and time again to not nearly perform as advertised. Consistently 150-300fps slower than advertised velocities. Underwood ammo however, consistently meets and exceeds advertised velocity, and it is cheaper!

Sad but true, I chrono'd them at 1170fps in G20 and 1135fps in G29 I couldn't find anything better for woods carry. I am going to have to start reloading. I'm sure it will be fun as well as cheaper. When I'm ready to pull the plug I will be asking for help on this forum.

You must be talking about the 200s?

That is still a pretty good load even if well below claimed MV.

It is true that handloading is the way to go - especially for this fine cartridge.

Sacrifice beer, dining out, entertainment, and Starbucks for 60 days. Sock the cash away for a reloading setup. You can be a reloader by mid march. You won't regret it.

Yes they were the 200gr. I have been thinking about reloading for awhile now but didn't start saving my brass until last year I have over 3000 so that should get me started,I now save all of it.
