Here's the scoop. Back in Nov my brother and I picked up matching brand new G20sf's. At the same time we ordered a 1000 rnds of Georgia Arms 180fmj's to break the guns in. The first day at the range, we both went through 3-4 hundred rounds and both guns ran perfect with all mags. We picked up all the stairline brass and got my Dillion 650 all set up to start realoading. Over the last couple weeks I've really been burning through the powder working up a couple different loads. 135 nosler and 180gr Delta precision FMJ. Through several hundred rounds through my 20 the 180's ran flawless. All at 1.25oal and some as light as 1100fps up to some hotter stuff around 1225fps. The 135's were a little different story, here and their, maybe every 50 rnds I would get a FTF, where the hollow point would hang up on the left or upper left side of the chamber, I eventually went from 1.25" to 1.242" oal and that seemed to fix things. Well last Sat I was at the range with my brother when my gun had the same type of FTF with the 180fmj's, I was floored! By this time my gun has 1500 to 1600 rounds through it and my brother's only has maybe 500. So we continue shooting and the next mag my brother shoot's he has the same FTF. Now I'm a little worried something is really wrong with my load. So here's what finally prompted me to check in with you guys, Im at the range today with my Buddie cause he's got a new Xdm 9mm he's been dying to shoot. My gun FTF like 6 times in 150 rnds with three different mags! 4 times with my 180 that always shot awsome, and two times with my 135's at the new OAL that I thought I had straightened out. By the way the gun is completely stock other than a 3.5# connector and a glock extended slide release. The gun was also Just cleaned and lubed lightly. Here's what I'm thinking, I dont think it's the mags, their new and really don't have many rounds through them, the follower is a little dirty but not bad. I'm thinking I have a brass problem. Some of them have been reloaded maybe 6-7 times and some are only on there 2nd loading. A few had very small smiles from when I was working up my 135 load but I threw 99% of those out. I did a very close look at the rounds that jammed and the round under it in the mag and neither one had any obvious signs that would lead me to believe they wouldnt function correct. Most of the brass has some scars and extractor marks on the rims. Im thinking after repeated loadings the brass might not be sized back down enough and isnt stacking and feeding right from the mags. Also the brass is cleaned and polished very well before loading. Im heading to the range monday and I've got 800 rnds of 180's loaded in brand new stairling nickle cases, im wondering if that fixes my problems. Any Ideas would be nice.
