I tried the original 120 grn. SB JHPs and had several jams. I also read several horror stories on another great Mak board at
www.gunboards.com. There were even two reports of "squibs", meaning people having their barrels ruined by bad rounds. Wishing we could get a big and heavy (for this caliber), hot JHP at a reasonable price, I started a letter writing campaign to LVE. They improved their quality control and the newer batches appear to be better. I noticed they also downsized the 120 grns to 115. So as far as I know they now sell "Silver" and "Brown" Bears, both in 115 grns. There have been many reports of this round jamming people's guns. Yet there are also several others who say it feeds OK. EG guns seem to feed it better than unmodified Bulgys. For excellant info and pictures on smoothing down your feed ramp, go to the other board I mentioned and search for posts by "Greg S.".
I'm going to try the 115 Brown Bears but won't adopt it as a carry round until I've shot several hundred and know it will feed flawlessly. For now I'm sticking with Hrndy XTPs for my HP round.
Can't wait to hear what other people think of the 92 grn FMJ.
