  1. There isnt as much chamber support of the 9mm case  in a pcc, as compared to a 9mm major custom pistols.

     

    But then given the longer barrel, less pressure is needed to make major in pcc.

     

    I have fooled around with diff loads up to 146PF, which didnt feel much different than 132 pf  with pcc.

     

    I like it the way it is.......no major in pcc.

     

    But if one were to go major 9mm in a 14.5" PCC, what load/powder/bullet would be best?  Heavy or light bullet?

    Kinda in the same boat looking,   I can't decide if I should just get the GMR-13 for less $$??   I mean, really besides the flared magwell what changed?   As far as I know it's still the same upper/lower, barrel, spring setup stock etc.

     

    I'm trying to justify the extra $318, where is it at?

    the gmr15 bolt locks open on empty......which is of limited value in uspsa.

     

    I have not seen a gmr13 magwell, but the flared magwell on the gmr15 combined with taccom funnel thingy, makes for very fast reloads which are critical to doing well in classifiers.

     

    There are two versions of the gmr15.   One is like $2400 as featured in Front Sight.....red anodized safety lever, thermal dissipator, and unique side charging handle and upper.   Other version is all black without those three features, and $1800.

  3. My JP FP broke today during 350 rounds of practice (maybe 6000 rounds total on this factory new gun).

     

    Discovered this while cleaning after range session.

     

    I believe the gun  fired many times with a broken FP!

     

    Its possible the FP broke on the very last round of the day, but I doubt it.

     

    So the GMR15 never failed to fire even with a broken pin.

    If you reload 9mm for your pistol, the same reloads should make a similar power factor in your carbine making is possible to shoot the same ammo without adjusting the charge.

     

    I assume this is with the 5.5 in. carbine barrel.

     

    In my 14.5 in. carbine barrel I gain about 160fps overall with my old production pistol loads.

     

    Question?.......Are most PCC shooters coming from production or open?

     

    In my case its open.......have not shot production for years.

     

     

  5. I have 4000 small rifle primers I need to use up, preferably with my stock JP  GMR15  PCC.

     

    Am I gonna regret the first batch I make?

     

    Does the firing pin hit as hard in a PCC as an AR15?

     

     

  6. Strange......all my glock branded 31/33's with taccom splice or TF 41+1 base easily drop free on my GMR15..

     

    Question?   Do you really care?    You only reload on classifiers with PCC, and those should be done with Glock 17 rounders from belt.

     

     

  7.  

     

    I'm getting 142PF with 3.9TG, 1.145, and 124 Montana Gold JHP's.

     

    Also,  136PF with 3.2TG, 1.145, and 147 Berry round nose plated.

     

    I sometimes use the 142 PF ammo when dealing with an array of steel.......as an open shooter I've become used to hitting steel with something harder than production PF.

     

    Couple times I've returned to re-hit falling steel when it was sloooowly falling with PCC.

  8. Some matches/clubs often have  targets beyond 50 yds.

     

    For those I would zero at 50 and utilize holdover for tight close stuff.

     

    Frostproof optic Nationals this yr had targets around 65 yds in the big bay down at the end.

  9. How long do the inexpensive unbranded 1/3N Batteries CR1/3N 3-Volt Lithium Batteries   last in lasers or red dots compared to say duracell?

    At 90 cents each for the above, I could live with a shorter battery life.

     

    Crimson Trace will only send out one battery per yr for free.
