    I tried the Taccom Magnetic Delay buffer system, Gen 2.  You have to do a LOT of experimenting to tune that system to your load.  Once you do, it is essentially useless for any other load.  I shoot three different PFs, depending on the match.  I was not willing to reconfigure the buffer every time I switched loads.  I will note it does do what is claimed.  It definitely does delay bolt opening.  That keeps you gun a LOT cleaner than straight blowback.

    I would be keen to try this out as I only use one load for IPSC. but I am concerned about what more can go wrong with the system due to all the (moving) parts, but in addition I expect it to land here with shipping and duties for another 50% so experimenting becomes expensive. and then of course it becomes a really expensive paper weight if I dont use it. If you only had to use one load would it have been a good contender for your firearm?

    Anyone have experience with the Scheel system?

     

     It’s cheaper than buying a Jp5 or mp5

     

    I’m still going to save for one of those models 

    I run it in my GMR15. Love the way it works. I shot the Scheel Gen 1, Kynshot and SCS back to back in the same firearm. I preferred the Scheel but the Kynshot was an extremely close second for me, YMMV. My load is about 137pf using VVN320 with a 124gr coated bullet. 

    I probably have about 10k through it with the scheel and broke a bearing on it. This perhaps one of the only reasons I will change to another system, but really dont want to splash on another system, especially considering out exchange rate on this side of the pond. Therefore I am considering it a consumable and will change it out periodically.

    With a 124 PD JHP and 3.8 N320 I get 126 PF in the JP-5. 132 PF with 4.0 N320. I would not us N320 with the JP-5 and heavy (147gr) jacketed bullets. You should use a slower powder with the heavier bullet in a PCC. By the way, all my loads 147, 124 and 115 have been about 5 PF less in the JP-5 than I had in my GMR-15 for the same loads.

    Any reason why you suggest not using 147 gr with N320? I use polymer coated with about 3gr and get about 135pf in mt GMR15. I would be interested to understand your comment. Thank you. 
    I did try a slower powder (maybe too slow, had Lovex 37.01 for my open gun) but still prefered the N320. 

  4. I agree with @ysrracer, dont over think it. The instructions are pretty clear given your choice of bullet and power factor. I am shooting 124gr polymer coated bullets using VV N320. My power factor is about 136 and I use 2 heavy and 1 light springs. The gun shoots flawlessly and I have not encountered any issues. Good luck with your setup. 

  5. I have about 500 rounds of ammo through my JP with scheel system. Different powders and bullets. There's probably a ton of different stuff you could experiment with, bullet weight, charge, buffer, scheel internal springs. My experience so far is the 124gr loaded with N320 at about 135ish factor has the least mount of dot movement. i am able to hit 2 As at a 20m target in sub .20 sec consistently. Doesn't prove much but under certain conditions it can provide useful information for R&D. I have done the same with 147, 115, 135 all with N320, did not surpass the 124gr with the current setup (for now) Tried more springs in the buffer but all came down to the original spec. To be honest there is probably some work I could do to further exhaust possibilities and research for the internal scheel springs in the system, to see how those perform but I think I am rather happy with the current setup. Its time to shoot more.

    I was able to finally install and test this buffer system.  Here are my observations.  I converted from the JP SCS in my JP GMR-15 with 14.5" barrel with pin and welded normal comp.  The system is short stroked.

     

    When I initially installed the system it was incredibly stiff to charge.  SO much so, I though it was going to be an issue.  Mind you I did install three springs in the buffer.  Soft springs in positions 1 and 3 and a stiff spring in position 2.  The system became very easy to charge after running about 50 rounds through the system.  Zero issues feeding MG 124 Gr JHP and 124 gr PD FMJ bullets. I did take out the soft spring in position 1 to do some additional testing with only 1 soft and on hard spring in the buffer.  I felt the dot moved more with 2 spring, so I installed the 3rd spring and ran about 250 rounds through the gun without issue.  

     

    After break in you can certainly tell it is a 5# main buffer spring.  Much easier to charge, and not as much force closing the bolt, than the JP SCS Short stroke buffer I was originally using.  I will be curious at the maintenance periodicity in spring replacements.  Both for the internal buffer springs and the main buffer spring.    

     

    Dot movement is minimal, shooting 124 gr bullets, at PF from 130-135.  I felt more confident shooting targets at further distances with quicker splits.  Hitting a 6-7" plate at 25 yds. at 0.12 splits.  

     

    Looking forward to running the system through the summer to see how reliable it is.  

    Thanks for the update. Mine is on its way from Chuck. Keen to get it going. Will hopefully be able to post some info with my findings in a month or so.

    I ended up getting one and like it a lot - it definitely softens the blow of the bolt going back into battery. For comparison, I previously used a Blitzkrieg 9mm hydraulic buffer with the spacer buffer weight. The one issue I've run into is that when the rifle has sat for a while, the buffer o-ring seems to stick in the buffer tube a bit and takes some force to free up and can feel a little slow to move. I haven't had any issues shooting it in a match yet, though.

     

    Will it actually make a difference in my shooting and make me a shooter, though? Probably not, though that could be said for most upgrades.

    Do you have any other feedback on the air buffer? Toying with the idea of the air buffer or the Scheel system. Any advice? 


  8. Thanks for the feedback everyone.

    Worth it is not something we can answer for you. Imo the Z8i is lighter has slightly better glass and a wider field of view,   Razor has a slightly larger eye box. Reticles are personal preference


    Garmil, I've looked at the specs but perhaps i read them incorrectly. Do you know how wider the FOV is compared to the Razor?

  9. So I've been playing around in 3gun for some time now and just purchased a new rifle. I'm looking at variable power optics which, here in South Africa is scarce and pricey.

     

    I've shortlisted 2, the Vortex Razor JM1 or the Swarovski Z8i BRT.

     

    The price tag on the Swarovski is almost 1000USD more here, so I would like to know if it's worth it? Yes it has 8x magnification but I'm primarily using it for IPSC (max 300m) and 3gun, so I don't think that Max power is a train smash. Any feedback with be appreciated.

  10. I was window shopping at Cmore's website and found the option to purchase dot modules for the aluminum bodies of their scopes. I have 2 of the aluminum scopes which work great l, but I also have a few modules laying around for the polymer scopes and the intention was to keep them for spares.

    Is there any reason not to use what I have in the aluminum bodied ones?

    Here's the link - http://cmore.com/store/index.php?app=ecom&ns=prodshow&ref=AMOA&sid=37lu5r6v5kh07fb482t87it6dsfjf479

    I've already emailed Cmore but thought you guys would have some input on it.

  11. I am unable to find a 0.936" gas block and most if not all of the dealers in South Africa have some from of a 0.750" gas block. Other than selling the bull barrel for an alternative, can someone shed advice with regards to turning the barrel down, up until the gas ports to accommodate the run of the mill gas blocks that I can find here?

  12. STI makes one size tube for 9mm and 38 super. If you don't use a spacer in the back of the mag you run the "potential" of the 9mm rounds getting "behind" the forward control rib, thus causing feeding problems. Rear spacer moves the round just far enough past the forward control rib to prevent this from happening. Now, do some have success without spacers running 9mm in STI mags? Yes, but it is hit and miss.

    Good luck

    Thanks will do my best to get them working with out spacers etc. Worst case i will have to get spacers

    Spacers and springs with followers, you need both of them.

    IIRC, the STI has 2 thinnish ribs and the SVI/SPS run 1 broad rib. I have not used STI mags but what Glk21C says makes perfect sense.

  13. Yes super mags will work, depending on OAL. you will have to play around with that once you get your gun.

    I have SPS mags that I use in both, my super and 9 major guns without any change.

  14. does the trubor mag come std with a spacer when the gun is bought? i can't remember seeing one. I thought that they were just 38 super mags

    I'm pretty sure yours will be super mags. 9mm Major springs and spacers are few and far between here in ZA. I suppose the 2 dealers may be able to bring those in for you albeit a bit of a wait.
