AHI

pff not Evan a starting load for 9 MAJOR it'll fit .

that may be your issue .Otherwise a drop of locktite may help. I use Glock liners and not had any issues.

Glock or some other brand of liner?

look 7 post above

Ill almost bet the head stamp is CBC. Thear are a couple others but that seams to be the most offensive.

be leave that is what I told you before.

your pistol ammo will/may gain100ish fps. decrease powder charge. No advantage of slower powders over faster powders.

hope I was able to help. I believe you will like sport pistol. I found the 135 in my case to be the best ballance of accercy, function and feel .

went to the 135 round nose. @1.125

at one time nickel cases were preferd for major. something about being more consinsit in volume.

less bullet in the case . the inside of a 9mm is tapered and can/will deform the base of the bullet. RECOIL IMPULSE in a pcc is different than a pistol. I shot 147s in a pcc at first then switched to lighter ended up with 135s with 3.0 sport pistol. Other reason I had feeding problems and switiched to a round nose witch had to be shoved so far into the case it was deforming the bullets.I shoot 3gun with a pcc not uspsa targets are farather out and smaller so accercay does come into the equation more. your BBI 147 is in the case less than a round nose 147 . Its all about the profile.

Its short . Can you load longer? if you have been using that length before with no issues then why would you have issues now? personally I feel that length is to short but I dont have a gun that requires such a short length. My loads for 147s are 1.135 ish. But they chamber in my guns they may not in yours.you asked about powder I answerd. In a pcc I would go to a lighter bullet. A 135 with 3.0sp should work . A 124/125 would need 3.8 sp.

this is what I was refereeing tohttps://www.egwguns.com/arredondo-docter-sight-adapter-for-jpoint not the one you wont but they have other combinations.

none of the ones I have look like the one on the left. not sure if it would cause any issues.

Ck with EGW they have a couple but may not have the combination you need.

re read this and I have a question based on an observation. When the various wet cleaning methods came about .I started noticing lots of brass splitting and other sizing issues.so could this new batch of brass been wet cleaned with some witches brew. That causes the brass to be "hard" in some way.That is one reason wet cleaning is /has fell out of favor locally. Any one else notice this?

Its dead Jim.

ok lets play what is the velocity of the 3.3 load. this is the first step to determan a load issue.

what head stamp is giving you issues? The reason I ask. I have a few cases that have failed case gauge. 1 is a tulimmo marked 9mm luger in measures 18mm length.All other diminutions are correct to be 9x19. Also have a PPU marked 9mm BROW.L That length measures 20mm in length.

bullseye and sport pistol are virtually the same per weight charge. you may or may not have to add .1 for sport pistol . SP takes up a little more space than BE. Stick to the bullets you have been using and length .(J-Ames bullets are no different and not any better)

its not the powder.

you probably don't reload but reducing the powder charge would help. Other wise a 308 flat wire spring will slow the bolt down some. would probably be insignificant thow. why can you not use an adjustable gas block this is what there made for,

3N38 6.2 GR Book max is 6.9@1207fps if you end up needing a little more.
