  1. Longer loads better, eg 115 jhp at 1.17
  2. Jp spring carbine or rifle length?
  3. I wasn’t answering your question (Look who I quoted). I covered ar9 ejection in my first sentence.
  4. Ar9 blowback ejection doesn’t matter if it’s reliable. Ar15 ejection is dependent on the gas, before 3 oclock not enough gas after 4 o’clock to much gas. Not enough gas isn’t optimal because you can get a undercharge and stovepipe. Too much gas is reliable but batters the gun and internals.... allegedly
  5. The 308 jp carbine is ar10 Yes it would be in the upper/barrel area and could potentially get in the lower/trigger parts. start with red sprinco. Shooting doubles or bills at 25 yds on a timer, fastest splits you can shoot and see which has fastest splits with best hits. another good spring is tubs flatwire @bwikel
  6. Trial and error is the only way to tune your gun to you. I tried 3 buffers, 4 loads and yellow to orange sprinco, jp 308 carbine and rifle, weights in weights out. The setup I listed about is what I had the best accuracy on doubles and bills at 25 yards it felt the smoothest and had a fast predictable return. Also proper cheek weld (not chin) having gun near my centerline (buttstock mass below shoulder line)s!houlders squarish, while rolling or pressing my right shoulder into the buttstock and squeezing in with my left hand about mid way on the handguard. That said every gun is going to h
  7. Post a picture or video of you shooting. That setup should have very little to no dot movement. I use a 5150 with jp carbine and 2 oz spacer in front of dampener iron city bolt. Total weight is 26-28oz if I remember correctly.
  8. +1 to this, possibly include more info next time. That malfunction is typical of not having a ramp/decent feeding cone or handcycling and not actually shooting. Maybe ask taccom Tim what he suggests? Good luck
  9. Taccom ramp(if they still make them) file you’re own ramp shooting innovations barrel and bolt

  11. remove bolt weight first see how that shoots, then adjust buffer weight. Also try varying gn of powder, see what gives you the best feeling and dot track. At the end of the day everyone is different and perceives recoil differently.
  12. What buffer? Does the bolt have a weight in it? With a fast powder like sp and using a rifle primer you should be able to take the weight out of the bolt. With slower powders removing the weight isn’t ideal because the bolt will open too fast and throw unburnt powder out.
