Hi,
I recently picked up a Glock 37 (45 GAP) and have been working up some loads for it. I've got a couple different bullet options in 185gr and I picked up a box of plated 200gr Berry's Target Hollow Point bullets to try as a 200gr option. I settled on a COAL of 1.070 based upon available load data for jacketed 200gr hollow points by other manufacturers. I loaded a couple dummy rounds the other night and have found that they don't "plunk" - they visibly won't chamber all of the way. I have to lower the COAL to 1.035 to get them to chamber freely. It seems that these bullets have a very long bearing surface, such that when loaded to typical 200gr JHP length it is hitting the rifling without dropping the COAL quite a bit.
I have done a lot of reloading over years and I am confident this isn't a flare/crimp related issue. I'd drop the COAL to 1.035 and give it a go working up but I haven't run into an issue with jacketed data being so far off from plated data. Though I would admit that I haven't done a lot of plated bullet loading. Adjusting loaded length in a short handgun case by .040 or so seems like a lot. I did see that Lyman lists data for a 200gr lead bullet, the Lyman #452460 popular in the .45ACP, with a COAL of 1.030. I might just start with that data and work up, just not sure how that compares pressure-wise as the lead bullet must have grooves.
Does anyone have experience loading these Berry's Target Hollow Points, especially in .45ACP or .45 GAP, and having to adjust COAL?
