Powder and primers last a very long time if stored properly. I've never done a comparison like y'all have but I've been given some 30-50 year old unopened cans of powder and primers and they shot great.
Good to hear a range report. 2800+ from a .277 cal 150gr in a case roughly 308 size from a 20" barrel is nothing to sneeze at. My 24" barreled 270 Win did right at 2900 fps with 150s! What kind of loads are you working with?
Those aren't terrible prices and they have a good selection. Almost bought some other powders (Grand and H4895 are calling my name) but I need to just use what I got! They have quite a few primers too.
I haven't done it often, but have removed live primers very carefully and reused them without issue. Not sure I'd use them for anything important like hunting loads though.
I've heard good things about Peterson as well, I just haven't used any yet. All new brass goes through annealing, some just do a chemical wash to get rid of the discoloration.
Looks like Midway has the 136gr .277 ones in stock. I'd jump on these but I already have a ton of other excellent bullets in .277. Also appears Scheels has several diameters in stock.
I love Starline in straight walled cartridges. I use it in 357, 44 Mag, 454 & 45-70. I've been interested in trying it for my 270 or 30-06. Like some others have mentioned, my go to for bottle necked rounds is Lapua. I'll be trying out some ADG for my 7mm PRC and Norma seems to be doing very...
Yikes, those ABLR's look like crap. I know they're soft and all but suprised they sold them. I've been keeping an eye on that website ever since someone on here mentioned it. Some great bullet options. They had 22 cal Trophy Bonded Bear Claws, which are wicked for deer.
Can't imagine the 140gr Partition or Accubond wouldn't put a hurting on an elk at any reasonable distance. I haven't shot any elk with mine but the 140gr PT has really impressed me on deer. The copper bullets are another option but they need more velocity to reliably expand where as the PT & AB...
