I've got a winter camping trip coming up where we basically go out to the woods on a piece of private property for a long weekend and shoot, so with that in mind I've started to make a list of guns I plan to take along with an inventory of my ammo - I want to be able to take enough so that I can shoot as much as I want without really running out of anything.
I'll probably have to pick up some bullets, but I have powder, primers, and a progressive press - it shouldn't take me long to bring everything up to speed.
Getting into the NV game, and converted my 300AAC SBR over to 2.26" sight height using a (knockoff) Unity riser. Then I realized I have no actual reliable 300AAC ammo to zero it (my current sub loads are a little too weaksauce for semi-auto usage, alas), and started making some progress towards fixing that.
Step 1: wet tumble and dry my bag of 300 brass. No pins, no problem. Shiny enough on the other side.
Step 2: get my 300AAC processing toolhead setup. OK, more exciting. It's been forever since I did any brass prep, and there were some delightful moments of getting brass stuck while I remembered that you really gotta run the brass wet when using a trim die. Power trim xpress was used as the trimmer, and since this was the first time I was using it, I had to do some tweaks. No big deal. The reality is that none of my brass needed trimming anyways (so far), and the one time the trimmer did touch one, it was well under the max trim length (but also over minimum). Everything gauged very nicely at the end, and the primer pocket gauge seemed to indicate I was good to go on the brass I tested. Once I get the vacuum connector I ordered off Amazon, I'll run off the rest and get them ready to load. I may also do a little experimentation to see whether the trimmer can deal with converting 223 to 300, which would really free up my 300AAC supply chain.
Also bought some brass off a dude on Discord, since I was out of 9mm brass (and questionable on 45 Auto, but that wasn't as pressing, really).
Mark7 Evo has a reasonable amount of compound leverage, I doubt it would be a huge deal. I have some bags of Winchester 223 brass I got when I bought some other stuff, so producing a little more 300 brass out of them would be high on my list.My thumbs hurt just thinking about converting .223 to 300ACC.
Give it a try. Most of my experience is comparing regular and mag primers in rifle rounds. I've done a little in handgun rounds. I'd expect slightly higher velocities, maybe 5-15fps. Your accuracy and SD could be better or worse depending on what powder and what powder charge. Just the usual reminder, if you are close to max pressure, back off the powder charge for sure, as a mag primer WILL increase it.Getting ready to reload some 45 Colt, wondering how much of an effect Magnum primers will have on some subsonic loads?
There is definitely something satisfying about feeling a perfectly seated primer find it’s way home.Finished sizing, trimming, swaging 1500 pieces of 223 brass. All passed gages. Then hand primed them. I like the feel of priming that way.
Also started prepping 800 pieces of brass for Garand loads.
