300BlkTalk

UPDATE: Loaded up 500 rounds, had exactly 5 that the bullets where loose in the case. I resized them again and they where fine. Not sure exactly why those 5 had to be resized twice, but it turned out not to be as big a problem as I first thought. Thanks for all the help.

Sorry, guys, I failed to mention that the 125s I loaded with once fired brass I bought from Midway. The 150s I am trying to load now are with brass I made myself from .223. All the brass is mixed headstamp. Kind of have a problem about re-sizeing the brass again, as I have primed all of them! Easy....

Guys, I just wanted to publicly say what an outstanding guy Rob Leahy, of Simply Rugged holsters, is. I first encountered Rob several years ago on the sixgunner.com site. In a post I said in passing that I was toying with the idea of making my own holsters. Rob messaged me and offered to help in any...

My next thickness is .010, give or take. Just checked 4 or 5 cases, ID runs from .305 to .307 on those. I did not resize them after turning the necks, but I did before. The outside diameter of my mandrel on the Hornady neck turn tool is .306.

Making my own 300 Blackout brass from .223 has been a PITA, but I finally got a few hundred done. I ended up having to buy a Hornady neck turner because so much of the brass was too thick in the necks. (Actually, my wife bought it for our anniversary! Now, that's a great wife!) I was using 125 grain...

I have for years used Hoppe's #9 to get out the powder fouling. Once the powder is almost gone I use a copper cleaner from Pro-Shot products. Once it starts to come out clean, I use CLP to oil the bore. Have had no issues.

This is just me, but I always crimp any semi auto cartridge, to include .223 and 300 Blackout. For my bolt actions, I do not. Keep in mind that you are relying on neck tension alone to hold the bullet in place. Say you load up a 30 round mag and shoot it. Each time you shoot it the bullets in the ma...

Well, my first time out with my new 300 Blackout. I put a Nikon 3-9x40 on it, had some 125 grain Speer bullets loaded up in front of some W296. After I got it dialed in, I had two 3/4 inch groups at 100 yards, 3 shot groups. I was very impressed, to say the least. I had one box of Remington 220 grai...

Been shooting and reloading for 35 years, but have never shot or reloaded for the 300 Blackout. I got a great deal on a stripped lower, and was tired of building 5.56 rifles and pistols, so I found another really great deal at CDNN on a 300 build kit. Just got it done today. I loaded up 100 rounds o...
