2021年8月15日 · Gents, PB by IMR was/is a great powder. Loaded up 102 grain SWC Eastwood PC in a Wilson 9mm ie; 1.015" OVL. Shot to center of target, 25 yards. Ran about 1080 fps. That was a nice load. Have a great week!

2014年4月13日 · IMR is discontinuing PB next year. I've gown to love it. Meters well, burns clean, burns "cool" (compared to something like TiteGroup.) Works great with boolits. I bought a stash, but it will eventually run out. What's a good alternative with those qualities?

2011年12月11日 · PB is the sole survivor of what was intended to be an entire line of propellants. The concept was to have a generic powder kernel that was porous, and to add the various inhibitors and additives to tailor burn rate, flash and other characteristics to the "sponge-like" kernels as needed.

2014年9月22日 · I changed from Titegroup powder to IMR PB powder because that is all I could find, never had trouble with the Titegroup. I'm reloading for a Ruger P95 9mm and SR 45ACP. I'm having trouble with the empties ejecting from the gun, either the slide doesn't open all of the way or it just won't open and I have to hand eject the empties. Here's what I'm doing with the PB: …

2013年4月6日 · I'm a Noob to reloading and I picked a bad time to get into it. As you all know powder is hard to come by but my local store has IMR PB Powder in stock. What's your opinion on IMR powder? I'm reloading 40 S&W 150 grain Boolits for target shooting during IDPA matches

2007年8月29日 · IMR's site says: Named for the porous base structure of its grains by which the burning rate is controlled, PB is an extremely clean-burning single-base powder.

2023年11月12日 · I recently got a couple cans of Dupont PB and was curious what its best used for. ive seen data for 1000fps loads in 40 S&W and use in 1oz and 1 /8 oz loads in 12 gauge

2011年4月5日 · The one problem I have with it is that it's really dirty. I'd hate to see what the older, non "cleaner burning" version would do. From lurking I've gathered that some of you had success with PB powder for clean-burning target loads. There are gaps in the load data available from IMR (nothing above 200gr in the 44 mag for example).

2019年8月10日 · Unique is the powder I think of when ever someone asks for a powder for the 45 colt. For decades it was THE ONLY POWDER even listed in many manuals. FOR GOOD REASON! I have some SR powders and like them. But IINM they are no more or at very least hard to locate. PB that I have is hordes for my 32/20 loads cause its simply awesome!

2020年4月4日 · I know IMR PB powder is mostly used for shotgun shells. I'd like to use it for reduced loads in 30'06 and 308W and 7.62X54r. Does anyone have experience using it with cast bullets? 102 grain, 155 grain or 200 grain boolits? Thanks.
