Title: New DoubleTap .44 and 10mm for testing
Post by: Intercooler on February 25 2013 04:15:21 PM MST
  Shadow and Chopinbloc I just got these today and will get a couple out to each of you. Interesting the 10mm is now rated on a 5" barrel like all the others  :o

    It hurt like getting a swift kick in the jewels spending for them but I still wanted some more answers.

I'm hoping to get my Chronograph all ready to test them all this weekend.

Sounds like some fun in the making!  I need a break from the rain and hail storms down here!  Storming as I type!  I'm almost caught up on the re-install of data on my new hard drive after the crash of the other main drive.  So I need some better weather to get out and do some velocity testing of the pull-down stuff...

As mentioned elsewhere I'm curious as to the 10mm 200gr Nolser results (all of:  velocity, expansion, penetration depth, and tear down).

Make that two of us.

I plan on sending them Tuesday with some others. I can't remember what's there now :-\

Supposedly that 200 grain 10mm bullet was designed by Nosler specifically for them.

   I looked back and Mr.Redbull got 1153 FPS on the 200 Noslers. Let's see what I get this week.

I'm curious.  Think you'll put a few through the Hunter and/or RZ-10 for velocity results?

Post by: Intercooler on March 04 2013 02:34:52 AM MST
   DoubleTap boxes are only 20 which kind of stinks. 2 for Shadow, 2 for Chopinbloc and 5 for the Match. I could do 2 in one of the others.

I'm curious also what you think of the 10mm-200 grainers. I was thinking about picking some of these up for deer hunting.
What platform do you intend to fire them out of?

 Went today using EAA Witness Match 4.75", EAA Hunter 6", Ruger Redhawk 7.5" and XD 9mm 4". Once again DoubleTap let me down but all my pistol/revolvers functioned awesome. Makes me want another EAA piece  :o This is after the Chrony rebuild with the Hillbilly setup on it which I love to death. Numbers aren't much different for the ones retested.

Setup with Ruger Mark III 5.5" barrel using Federal 745 36gr .22LR: 1045, 1044, 1045, 1050, 1059. Average = 1048.6 FPS/ 88 LBS


10mm
PPU 180gr JHP (Match): 1032, 1029, 1007, 1013, 1044, 1028. Average = 1025.5 FPS/ 420 LBS
PBR 165 FMJ V-Supreme (Match): 1356, 1334, 1377, 1358, 1342. Average = 1353.4 FPS/ 671 LBS
Winchester 175 Silvertip (Match): 1216, 1220, 1212, 1190. Average = 1209.5 FPS/ 569 LBS
DoubleTap 200 Nosler (Match): 1151, 1160, 1143, 1159, 1165. Average = 1155.6/ 593 LBS
DoubleTap 200 Nosler (Hunter): 1218, 1209. Average = 1213.5 FPS/ 654 LBS
PPU 180gr JHP (Hunter): 1067, 1088, 1069, 1068, 1065, 1069. Average = 1071 FPS/ 469 LBS
Winchester 175 Silvertip (Hunter) 1299, 1266, 1291, 1263, 1281. Average = 1280 FPS/ 637 LBS
PBR 165 FMJ V-Supreme (Hunter) 1429, 1421, 1437, 1423, 1417. Average = 1425.4 FPS/ 745 LBS

In 10mm the DoubleTap couldn't hit the box flap even in a 6" barrel. Expect 1200 FPS in a 5"!  ??? ??? ??? ???

  As for the .44 Magnum:

DoubleTap 240gr JSP (Redhawk): 1375, 1385, 1366, 1363. Average = 1372.5 FPS/ 1004 LBS. A cool 125 FPS off on this one with same box flap revolver they list  :'( :'(
DoubleTap 300gr Nosler (Redhawk): 1262, 1250, 1252. Average = 1254.66 FPS/ 1049 LBS. Only 75 FPS off flap rating on this one  :o

Okay. All my DoubleTap questions are answered now and not another penny spent!

This one is mainly for Shadow and that early Underwood 9mm you tore down that I thought was like +P:

Winchester NATO 124gr FMJ (XD): 1203, 1181, 1201, 1165, 1213, 1210, 1208. Average = 1197 FPS/ 395 LBS
Underwood 124gr JHP (Old) (XD): 1254, 1259, 1244, 1244, 1261, 1242. Average = 1250.66 FPS/ 431 LBS
Underwood 115gr FMJ (Old) (XD): 1288, 1313, 1302, 1283, 1301, 1309. Average = 1299.33 FPS/ 431 LBS

My Handloads using those 260 grain Devastators as tested by you showed some good results as compared to the DT stuff...
1454 fps was your average... ;D

Post by: The_Shadow on March 04 2013 06:07:52 PM MST
Intercooler the Underwood 200XTP load you show as 8.8 grains

but in my testing 9.4 grains of 800X yielded 1250+, and I think someone else posted the same 9.4 grain from pull-down.

See Redlines post here; http://10mm-firearms.com/factory-10mm-ammo/finally-5-underwood-10mm-ammo-disections/ (http://10mm-firearms.com/factory-10mm-ammo/finally-5-underwood-10mm-ammo-disections/)

Yup! Did you see how close I got to Mr.Redbull on the Nosler 200's? Within 2 FPS average... we always did match up well even different places and Chronographs. I'm loving my setup on the Chrony with all the new parts and all. So happy with how everything shot today too!

No more doubts on the DT ammos.

Thanks for the two gun comparison on that load.  Average of 58 additional fps and 60 foot pounds.  Not bad.  I wonder what that load achieves from a 6" barrel.

The Hunter is a 6" barrel.

My bad.  I thought it was a 5.5" or something around there, but still under 6".  Good to know.

This very much. Gonna be interesting trying to get that 400 gr behemoth to stop in gel.

What ya got that shoots a 400gr?  :o


The 200's left out yesterday with a bunch of others. The Nosler and PowRBall will be interesting! In your opinion although we haven't done the Hex plated, PowRBall or Nosler what is looking like the best HP? Also in there is a couple of Winchester Silvertips although they have have been done to death.

Maybe he's gonna load up one 10mm round with two 200gr Noslers stuffed in it with 1 grain of 800-X and a Large Magnum Rifle primer? ;D
Title: Re: New DoubleTap .44 and 10mm for testing
Post by: Raggedyman on March 09 2013 08:25:14 AM MST
Yeah sorry I meant 300 gr had fours stuck in the head from .44, I guess.

So far it looks like 165-180 gr bullets do best, in my inexpert opinion.

.44 bullet heavy. Go deep.
