Some recent Chronograph videos. DoubleTap, Underwood (improved 200's) BB

[Intercooler]

   Waiting on my new batch of 200's from Kevin, but it looks like he has stepped them up! This fellow 10mm shooter did a good job on these videos. Poor DT!

Just got a box in yesterday of the 200's XTP.Man it topped at 1299 on that video you posted.

Those are moving right along!

Oddly the DoubleTap hasn't been working shooter to shooter.

I just clocked the Underwood 180 GD and 200 XTP a few days ago.  This ammo was purchased from Underwood within the last three weeks.  Fired in a Glock 20 with KKM 4.6" barrel.

The 180 Gold Dots averaged 1308 fps, but the 200 XTP's only managed 1167 fps....

Sounds about right out of a Glock 4.6" barrel. I think his 200's have changed now though and I haven't been able to get up with him to see what my order is.

200 XTP's only managed 1167 fps....

Buffalo Bore rates their 200gr 10mm ammo at 1140 ft/s from a Glock 20. So, Underwood is good.

I like the videos!  That Underwood was cookin'!  Good work.

The tester in that first video above got 1265 avg in a 4.6" bbl with the Underwood 200 XTP......100 fps faster than my batch, while my 180's were right in line with other shooter's results.  My understanding is that the Underwood velocity ratings ARE from a 4.6" bbl.

Not ragging on Underwood at all, I'm very pleased with the quality of his stuff.  But my particular lot of 200 XTP does seem to be slower than other reports I've seen.  No matter as I bought these just to try and normally shoot handloads.  Interesting stuff nonetheless.

Look tomorrow for my testing of Underwood 200's. If I get my .44 tomorrow I may just do them then. FWIW I averaged about 1212 FPS on the old 200's out of the 4.75" barrel.

I have some 155's that I want to do too which are EXTREME!!!

Sad to hear about the Double Tap ammunition. I thought that it would have performed better than that.

I feel the 10mm community owes Double Tap a debt because they lead the charge on bringing full power 10mm ammo out.  Hat's off to them for taking the risk and showing that a robust if small market existed.

But, they have certainly been eclipsed in performance by other boutique makers who have followed their lead.

True Mike McNett was the first to come out with "full power" 10mm ammo.  He started out with 4 loads in 10mm, and now he's where we see him today.  And at one time his ammo did chrono relatively close to advertised specs.  A couple of years or so went by when good 'ol Mike decided to double-cross us.  First, true velocity fell below anything reasonable compared to his advertised claims which is where we're still at today. 

Second, when he first introduced Montana Gold bullets to his lineup he decided not to let anyone in on it, allowing it to be a rude awakening to the purchaser when it showed up at their front door (we still thought we were getting XTPs that he listed as "controlled expansion").  And to top it all off, with lowered velocity we still get the pressure signs as when the ammo was loaded at higher velocity, suggesting he switched to a faster burning powder, I can only guess, to save money. 

And now that he considers himself above the rest of us, he's disappeared off the face of the map (even from his own forum where he'll only show up to post "sales" and such, disappearing as quickly as he popped in) and clearly doesn't care what any of his customer base thinks.

So, that said, I would consider the "debt" paid, and that he was lucky to get what he got when he did, putting him where he's at today, still treating us like we don't matter and never did, while at the same time going against what he preached from the git-go.  Maybe it's hard to tell, but I will NEVER purchase Double Tap ammo ever again.  Many others don't anymore and won't either.  And to that end, Rock On Underwood!

I agree with 'REDLINE'. Things started out well (we should thank him for that), but lots of issues started popping up on Internet sites and McNett did not appear to respond.
   
Five years ago, I emailed and called, leaving messages over a three or four week period. I wanted to pick up another 1-2K rounds on my way back from Wyoming. My drive took me through Cedar City, UT on the 15 Fwy. No response of any kind. Guess that kept me from picking up weaker loads and bullets not intended for self-defense.
   
Funny, today, after five years, I received not one, but two emails from Double Tap. He's offering a 15% discount until the Fourth of July.

Wonder if he's feeling the competition from Underwood and others. I've bought from Underwood and will continue to do so. I think Underwood has gotten our point about what we want.
