I've had my .358 BLR for 15+ years now and it's one of my favorite rifles and cartridges. I just picked up some 200 AB's and loaded them up with MR2000 as the data shows some decent velocities, I won't know until I run them over the chrony. I've had pretty good luck with TAC and last thing I shot using it was a doe at about 200 yards with a 200 Hornady around 2550 fps. In one side and out the opposite shoulder. I've actually had pretty good results, maybe better, with Xterminator in it and my 356 Win. I've never had a misfire in mine.
