I wrote this 4 days ago, but thought maybe it was too "snarky". So I didn't publish it because that's not my intent. But with no responses in 4 days, well, something should be said... I use Ziploc Freezer bags. Granted, reading a Post-it note through the sandwich bags is easier, it's just that the f...

It's like trying to package an elephant. Is it a big elephant or a little elephant. Even little, it's still big and depends on the elephant. Also things like muzzle attachments and optics. Here are a few ideas though. 10.5" AR w flash and scope, fits perfect in a 28" Condor rifle case. Not really st...

I haven't shot that bullet, but I've run the NOE 311-230 down to 2.010" with A1680 and my 12ga patterned better. Running gas checks kept the group on the paper... if I was close enough. Ultimately I moved the OAL out to 2.110". Then adding a gas check made it shoot even better. With IMR4227 this is ...

My son loads those bullets to 2.075" with 11gr A1680 with no crimp and gets 1000 fps from an 8.5" barrel. Can't say that's good or bad because I've never shot one. I suspect yours might shoot a little better with a shorter OAL. Also the everglade plated bullets I've used have been pretty soft and ma...

Might be of interest... 18gr - H-110 behind the Speer 125gr SST shot almost as accurate, and similar to my 125 SST's w/ 17.8gr (my favorite), but with significantly more erratic velocities. Accuracy fell off above and below 18gr for me, but I never went much higher to really see. The goal was a chea...

Ive fiddled with backing off the crimp feature on the bullet seating die quite a bit; backed it off more than one full turn.

The bottom of my Hornady seating die is 0.85" off the shell plate... Not the bullet guide that floats out the bottom, but the die bottom itself. Just saying for reference.

125gr SST with 17.8gr H-110 and Wolf 223 primers at 2.100" with a 3/4 turn factory crimp into the cannelure shoots one hole out of my 8.3" BA Hanson barrel at 50 yards. I'd need a scope for 100 yards. Awesome load, one of my "go-to" loads. 1922fps from my conservative chrono. Cold soaked and tested ...

That little bit of depth won't mean that much. Your cartridge cases might be running a little short. I trim to 1.358" on the case and 2.100" centers the 125gr SST up pretty good. I'd make it look good before I worried about a few thousandths... because we all know looking good is important. Ya know,...

Sure.

You would need to seat the bullet further into the case, but it looks pretty crunched on already. 

For cast in a Dillon, I run the RCBS 300 Blk size die with the 0.309" expander from a 7.62x39 set ( Decap Unit -.310, but it measures 0.309") and then use the 30 carbine funnel in the powder measure for a little bell.

For non progressive the NOE mandrels in a LEE universal sizer work great.
