I really appreciate the help guys.
I did pop the primer out and it doesn't look like the gas went up the side. The primers do feel a little loose going into the new brass but I don't see that relating. Maybe it does?
With the once fired I can't measure any difference in primer pocket Dia. I...
Yep make sure your shell holder is actually touching the die when sizing.
The press will flex when you are resizing and this is where problems can start.
Also make sure you have enough lube on the side of the case to help.
If that doesnt work you may have to get a different die.
For those of you that are shooting the 300g SMK and have to seat the bullet quite deep in the case, what loads of h1000 are you using?
I got a nice 5 shot group with nos AB 225 under 89g H1000 2815F/s at 100y yesterday but the 300 SMK were all over the place. I had the 300s loaded at the same...
I am about to chamber my first 338edge.
The reamer I have has too short of a throat I'm thinking for the 300SMKs, which I would like to shoot. I have a throating reamer on the way. If I throat it for the 300 SMK how well have these shot the shorter hunting bullets? What bullets have you guys...
What would you go with? I hear the 40 deg is easier on the brass, less strech.
I will be ordering a chamber reamer soon and I may just order a resizing reamer as well. Anyoune used both? Is the 40 or improved that much better?
Thanks for any help deciding.
A few points some already mentioned.
Stay out of dougnut.
Should have one bullet diameter in case- .308 bullet should be seated in .308 or more.
What you can do is load a round that just fits the mag- make sure you have more than .308 depth in case.
Take you calipers and set them to .307...
