I spoke with Kevin today and they have been changed. If you buy the current lot on the site you are good.

Did he say how much he backed off?

Intercooler · January 13 2014 09:50:33 AM MST

Nope. I hope they would give 1200 FPS in my barrel. In a Glock 1175 FPS.

Range Report!

Edit: 1175 sounds like a nice compromise. Though, someone (Yondering?) states 1175 would be too much with that particular bullet.

Hope he chimes in, I was looking to place an order to test some but would like to hear what he has to say first.

Anyone purchase the new lot yet?

You did I think? Are you sending a couple over?

mt10mm · January 18 2014 07:02:43 AM MST

Yes I did, ordered 3 boxes but not here yet. How many you want to do a complete test? I ordered 3 with high hopes for my glock20. This is the load I want to use so I hope it works out for me.

Do we need or want 6" barrel data? One for the pull-down and maybe 5 for velocity. I can split them between the two if all the readings are good. I haven't had issues all that much anymore and stop many times with just two good readings as of late.

I will send you as many as you will need to do your testing. I think 6" would be a good idea, lots are deer hunting with the 10mm and think this 220 would be a great load for that.

When I do swaps with other 10mm owners I typically do 8 per ammo.

mt10mm · January 18 2014 05:23:18 PM MST

I will let you know when they get here and they are on they way to you.

Intercooler · January 18 2014 06:35:07 PM MST

I can send you the new PBR stuff when I get it.

My underwood ammo order came yesterday and went out to test some. Fired 28rds total of UW 220hc. My 4th gen glock just does not like this 220gr ammo, I had many FTF.

I will send you 10 rds as promised and then going to sell the last 2 boxes

I'm sorry to hear this. Did it seem scaled back a little?

What barrel and spring setup did you use? If you went to a 3rd Gen I bet it would spit those 220's out with no problem. Do you plan on swapping anything? The reason I ask is other high impulse ammo might give that 4th Gen fits as well.
