Blitzkrieg vs Taccom comparison & range chrono results


Recommended Posts

finally made it to the range to test my Taccom ULW 5.25" barreled upper with Quarter Circle lower ..  used 124gr plated bullets  --  Titegroup powder 

 

  4.0gr  bullet speed 5 shot average ---  110.0 fps  ----  P.F.   ----    136.3 

  3.8gr  ------------------------------------------------  1059 fps                          131.2

  3.6gr ------------------------------------------------   1042 fps                           129.1

 

Taccom 3 stage buffer w/spring supplied by Taccom -- I found it to be a bit snappy using 4.0gr of powder -- dot rise was up and to slightly to the left..  found that the 3.8gr of powder the dot  hardly moved … 3.6gr power dot did not move at all .. 

 

Blitzkrieg buffer w/.223 carbine spring  .. 4.0 gr powder - - dot rose more than the Taccom buffer, but felt recoil was less ..  3.8 gr powder -- dot rise & recoil was much less .. 3.6 gr powder dot barely moved and felt recoil was very mild … 

 

both buffer systems power factor was nearly identical...

 

I could not do any double taps because this range does not allow ANY RAPID FIRE.. you are escorted off the property and not allowed to return ...

 

I plan to load 3.8gr Titegroup using the 3 stage Taccom system and go to a different range tomorrow so I can shoot doubles ..

My preferred testing method is the “doubles drill” at 10 or 15 yd.

 

Drive it hard into your shoulder, lean heavily into the gun, and rip fast pairs off as quickly as you can at 10 to 15 yd. Take care to get the sight fully centered and the rifle still again between pairs.

 

Do about 10 reps per target, and use one target with each different recoil spring or load that you’re testing.

 

This really lets you see the trend in where your second round is going to land whenever you’re shooting as fast as you can work the trigger. ;) 

 

(Equally important, of course, is how well that particular load shoots ar 25+ yards. So do both!)

I went through this exercise last weekend, shooting doubles as MM mentioned... I was shocked at how much difference varying weights, springs, and barrel lengths made.  I figured most of it was placebo effect...  nope.  Measurable differences in terms of dot movement and second shot impact at speed.

+1 to mm post, if you’re not ss the blitz try a jp rifle. If you are ss the blitz try at minimum the red sprinco. Take the travel 1/4” past trigger reset(if ss) Good luck hope you find what works. Spoke with Brian today they turned the ss weights to .994 so it should functions in most if not all tubes.

I don't suppose Brian indicated he would turn down prior SS weights under warranty?

 

Didnt ask that, give him a call or text. The number listed is his cell.

What's more important to you guys... Felt recoil, soft as possible w/o sacrificing PF or as little Dot rise as possible? I would think that if the gun is shooting soft, the dot rise will be minimal...

 

Not necessarily so.  My PCC with a 14-1/2" JP barrel, Blitz 2007 and JP .308 carbine spring has less dot movement at 138 PF (98 gr Eggleston + 4.6 gr N-320) than it does with a lighter less recoiling load.  I've tested a few barely sub-minor loads that are very soft recoiling but I'm getting a bit more dot movement.

Gotcha, I'm new to this whole PCC thing, I'm still learning the in's and out's. Thanks for the info.

I would say....that your results have pretty much been what I have found......it is subjective and there is very little difference between the two systems. Basically splitting hairs and at a match, you would see zero difference in stage times, and hit factor.
