FTF problem w. hot 10mm loads

Discussion in 'The 10 Ring' started by robert91922, Jul 1, 2012.

  1. Founding out it is not a crimp problem I stretched mag springs on all of my 6 mags:

    but it didn't solve my problem. Anyway, I still suspect weakened mag springs because my less hot (mild target) ammo works flawlessly, so a friend of mine gave me 3 Aredondo springs for Glock magazines. They are much longer and stronger than oem, I needed pretty more strength to assemble mags back together w. them.
    The next trip to range within few days will show if this is it.
    Until then I will carry my 6,5" .44 magnum Taurus sixshooter on hunting trip. It is a good, powerful and reliable performer but a bit too heavy (3.66 lbs) to carry arround on these hot days :faint:

    Hello Robert, I'll try to follow up to see how you make out with the change of springs.
    In the mean time let me invite you to this new 10mm Forum...many people are joining up as they find there way! Hope to see you there too.

  3. These Arredondo mag springs fixed my fail-to-feed problem. In fact they are Wolf +10% springs, just distributed by Arredondo Accessories. Also had to change main recoil spring in my 3-spring DPM recoil system to weaker (from silver to yellow).
    And just like I have read in a related thread here on GT, the slide remains open when last 1 round still left in mag. That doesn't bother me much because first 13 rounds feed flawlessly with any of my full-power ammo.
    With oem mag springs I had feed only 14 rounds into mag (to take easy on spring) and now I barrelly push 13 rounds into. With 1 in chamber as well it would suffice for any boar/bear encounter in woods. Our brown bears are rarely bigger than 400 pounds btw. so no sweat :cool:
    Currently I have 6 mags for G20 so I ordered another 3 Wolf+10% springs from Arredondo.
    For further maintenance I will just empty my 10mm mags when put them in a locker.

    Robert, if you need mag springs that heavy to make the gun feed correctly, your slide speed is too high with those hot loads. The fixes are a heavier slide, muzzle brake, or stiffer recoil spring. The recoil spring is the least effective, but the easiest.
     
  5. If I change the barrel from 4.5 to 6 inch (same brand and model) would it be helpful to decrease slide speed or would make it worse?
    Muzzle brake is out of question because of possibility to temporary blind me when shooting in darkness.
    In fact I am planing to get 6" barrel to increase bullets speed, but if that would increase slide speed as well I won't buy it cause I barely fixed this FTFeed problem.

    Just the longer barrel alone will probably increase slide speed, not what you want.

    You should re-consider a muzzle brake, if flash in dark conditions is the only issue. Using a low flash powder, it's not any worse than shooting without a brake. If you're using a high flash powder like Blue Dot, you could be "temporarily blinded" without the brake anyway.

    If you can get some stick-on wheel weights, you could put some on your slide as a temporary experiment to see if the extra weight cures your feed issues.

    Replace the guide rod and spring to a heavier spring. Factory springs are weak as they are for lower power factory load that most people buy.
