Drop the round in the chamber, send the bolt home. Works every time. Also, you can single load from a regular old magazine. Just put one round in it
Great idea, till you have your first slamfire.
It used to be that the community accepted that slamfires only came from Garands/M1a's. There is a lot of accepted wisdom that is total bunk. I recall absolute and total denial from shooters that AR's could slamfire. Technical descriptions on how the firing pin could not reach the primer, does not matter that the firing pin is free floating, only high primers cause slamfires, etc, etc. And then accounts of slamfires in AR's started dribbling in.
The angry denial is still there, but the more they slamfire, the less and less angry voices.
I had one. It was during 200 yard standing in Highpower. I was shooting loads with the new brass WSR. A primer that Winchester designed to be more sensitive than the old nickle plated WSR. I dropped a round in the chamber, lowered the muzzle, and dropped the bolt. The slamfire took a divot out in front of the firing line. Everyone saw it, and big scared eyes looked at me, and I knew they all thought "Mr Slamfire is going to kill us all". I was plenty scared too.
The shooter I was squadded with, during the relay change, laughed at me. But the Range Gods are fickle. His AR slamfired during his standing stage. His rounds were primed with Federals. The most sensitive primer on the market.
Now he is a Distinguished HM and has a President's 100 patch. I am not a new shooter either. We think we know how to reload our ammo. I seat all rifle primers by hand, and verify that they are below the case head. I know it was not due to high primers.
The accounts I have read on the web, all that I can recall, the slamfire occurred standing. Pointing the muzzle of the rifle down accelerates the forward motion of the bolt and just that little extra speed is enough to set off these extra sensitive commercial primers.
That is why the NRA/CMP won't let you load your rifle on the stool. AR shooters used to put their muzzle on the stool and drop a round. It only took a few slamfires through shooting stools before that was banned.
I have loaded the last of my brass WSR, they also eat up firing pins when they pierce. I was able to purchase a lot of CCI#41's before the election panic drove prices sky high. So I am using the least sensitive primer I can use.
I no longer drop a round in the chamber and hit the bolt release standing. I drop a round, hold back on the charging handle, hit the bolt release, and let go of the charging handle about half way down. I also bump the forward assist.
During rapid fire sighters, I load my single round sighting shots into my magazine. Remove mag, load mag, insert mag.
Long range prone. Well I don't want to break position. You know you are laced up in that sling, it you don't want to move that elbow.... I have not figured out a way to safely lower the bolt. So I toss a round in the chamber, point the muzzle at the berm, and hit the bolt release.
