I made my first 24 rounds of 30-06 yesterday afternoon but wasn't able to get to the range as I had other things come up yesterday
Wow this is a lot more involved than reloading pistol ammo obviously.
I started by laying out the brass standing up then gave them a good spray on all sides with Hornady One Shot case lube. Let them dry for about 5 minutes then proceeded to size/deprime.
Followed by trimming some of the cases, as some were 2.485" - 2.490" (max being 2.494"). But I had a few that ranged from 2.495" - 2.500". I bought the cheapest trimmer and debur/chamfer tools I could get since I wasn't sure how much rifle reloading I plan on doing yet. I went with the Lee cutter and lock stud, shell holder, and chamfer tool. Cost me $28 and works perfectly! I recently bought a DeWalt drill so I just threw in the shell holder and brass case, then inserted the cutter tool and trimmed the cases down to 2.485". Then used the chamfer tool to remove the burrs inside and lightly smooth the outside edges by spinning the case in the drill and lightly pressing down with the chamfer tool. Then wiped down all the cases with a shop rag. The rag seemed to wipe the lube off fine and I didn't think I needed to tumble the brass in the media. Hornady says their case lube isn't petroluem based so no need to worry about contaminating the powder?
Big props to 'jpm' for letting me know about the Lee Perfect Powder Measure I got for about $24 shipped on amazon. I did a lot of research and it was quite apparent that most powder measures (including my hornady measure) don't throw the stick powders like IMR-4064 very well. So I got the lee measure dialed in and it was within +/- 0.2 gr every throw! Some throws were exactly the same as the last throw which was great
My lyman manual had the minimum charge for IMR-4064 being 48.0 grains and the max being 53.0 grains. So knowing the problems with hotter loads/heavier bullets in the Garand I figured I'd start just above the starting load.
Load:
~48.5 gr (+/-0.2 gr) of IMR-4064
3.30" COL
150 gr Hornady FMJ BT
HXP brass

The only concern/question I had was in regards to headspace. I bought the Lyman 30-06 case length/headspace gauge and all my rounds except 1 seemed to be just BARELY above the max headspace reading as noted on the gauge. I attached some photos showing the difference between the round that was flush with the gauge and one that was just barely sticking up from the gauge. Is this safe to fire? What is causing just 1 out of the 24 rounds/cases to not be flush? I lubed them well and sized them all the same way, just that particular piece of brass?
I had no issues seating the primers into the crimped primer pockets as well, went in as easy as my small primers in 9mm/357 magnum.
Also I went for the longer COL (compared to what is stated in my lyman manual) as the HXP ammo I measured to be ~3.323". The manual says to have COL of 3.230" which seemed short to me.
Using the Lee 3 die set, I applied a light crimp using the FCD. The instructions say to screw the die in until it touches the shell plate. I did that and then screwed it in another 1/4 turn or so. I could see the collets (or whatever they're called) in the FCD compress (just a bit, not completely closed) on the upstroke as it crimped the case. Is there a need to apply a heavy crimp to these cases?
