I think an attempt is being made, claiming Berrys and Ranier use a thick plating ?
IF, I read into this a bit, could be wrong but you never know about peoples perceptions. One might be swayed to believe plated can be loaded to high side jacketed spec. I'm talking about Berrys and Ranier here, don't confuse either with Speer TMJ because that's a different kind of plating. Don't know how, but I've shot enough to know apples from oranges. I'll share this with you, I shoot in a climate controlled, indoor range having a concrete floor clean enough to eat off of.
Seperated plating on range floor is telling.
Berrys and Ranier use a soft core lead that's not bonded to plating. So, some care need be given when crimping and DO NOT drive these bullets at high side jacketed velocities. Both Berrys and Ranier are specific about loading their bullets.
Kind of like that sign, " Caution Wet Floor." Heed caution or run a risk of busting your butt.
Polygonal barrels and lead. We know polygonal bores literally shave lead from soft lead, fouling barrel. Doesn't much matter how thick you think the plating is, soft lead core is going to distort as plating is pulled into polygonal grooves.
Are plated bullets safe for your Glocks ? Yep, sure are. I shoot a lot of them at mid-range jacketed velocities. My favorite is 115 grain Ranier ball on top of Titegroup.
