Wife was gone, nothing on the "DO" list, clouds opened up . . . . . Time to go to the indoor range ! for the Second Round of Break in ! Previously put 200 rounds thru it and no hiccups. This trip: 200 rds 50 rds of Winchester 165 gr FMJ 50 rds of American Bullet 180 gr FMJ (don't know where i got these!) 50 rds of PMC Bronze 165 JHP 50 rds of Remington HTP 155 gr JHP Loaded up the mags and put a little extra lube to the slide rails. Hung a silhouette and started banged away, not paying attention to accuracy just round count and keep it going at the target down range. Run a brush & swab thru the barrel every 50 rds, relube slide at 100. Running smooth slow and fast fire. Then WHAT THE HELL ! ! a FTF ! Remove the mag, take a look, the slide made it half forward, and the round is half in chamber but still on an angle. Pulled the slide back to lock. The round is still half in half out, pushed up by finger tip and it falls out. case has a scar, mid case, length wise, and a good burr on the base lip? Looks okay otherwise, even length, put it back in the mag, lock and load........Bang it goes down range okay. This happened X5 ALL from the "American Bullet" 180 FMJ. This ammo was noticeably weak compared to others shot. So I believe it just didn't have the OOMP to give the slide a proper 40 cal cycle kick. All worked good other than that. Ran a brush and swab thru it before the final three round test. This to see if the parts are enjoying each other by now(400 rds), and the group should tighten up. Again kneeling on one knee, supported by a pipe across the lane. Tilt the head back to get the bifocals.........bang, bang, bang. Okay.......it did tighten up ! and still consistent with the earlier targets showing ever so slightly high and a pinch right. Again my POA is front post centered and its top on a plane 3 to 9 oclock. And as before target @ 10 yds. Have to move outside for longer distance test as the lights here indoor . . . suck. And RAMBO in the next lane is rapid firing an AK47. Time to head home anyway. So far I have to give this SA EMP 4" 40cal a big thumbs up ! The shape of the grip, in circumference, and length make it very easy to get comfortable. I would like to see some Hogue or Pachmayr finger grove grips, rubberish type, but thats me. target attached. ENJOYING !............ And it was $200 less than a 4" 9mm !
