I Googled it when I got home and found several occurrences of that happening. Because no energy of the carrier is consumed by picking up and moving a cartridge from the mag to the chamber, the carrier still has all of its inertia/momentum and the floating firing pin is still travelling top speed when the bolt slams shut. EVERY case that I had read about this happening was the exact same scenario as mine, the cartridge was placed in the chamber by hand and the bolt was let fly. Boom upon closing. Done it a thousand times. Never happened for me. I have a single shot 17 rem AR-15. Every loading is like that. 300 times each trip in 3 trips to SD. I wonder if firing pin is a hair longer on some instigating the issue. I know they are all not the same.

But doesn't the bolt fly forward every time it chambers a round by itself as in after the first round is fired?
How is doing it by hand different than what the rifle does by itself?

They say that stripping the round out of the mag slows it down enough that it doesn't slam fire. AR is a push feed. I really don't buy it. I think there is some other issue going on. Imo.

Something is up here. It is not physically possible for the firing pin to reach the primer with enough force in an out of battery rifle, assuming it is to spec.

I don't see how the firing pin could reach the primer on a fully seated cartridge if the bolt was still out of battery.

If you notice the next chambered round usually has a very small spot where the firing pin floated forward and touched the next round when it chambered it. I have been told, not tried it yet, that if you use SP primers in place of SR primers it will run away or go full auto after the first round is fired. The cup is too soft on some SP primers and they will fire upon going into battery. It will run the mag dry.

Picked up a Winchester XPR Titanium SR in 350 legend today. Hoping to mount an extra scope I have in gun case later this week to see how she shoots before I decide whether to mount a new scope on it.

Finally roughed in the XPR 350 Legend this morning at the range. Had roughed in at home for 50 yards.
Shooting 180 grain Federal soft lead and Winchester 180 grain soft lead at home previously (50 yards) and at Sugar Ridge range today. Surprisingly, hitting about 1 inch high at both 50 & 100. Managed to tighten groups to slightly under 1" at 100. But will see if it tightens up on another trip with less wind. Today's winds were at 10-13 mph quartering across and down the range from the left. Only thing I noted firearm is that trigger is stiffer than I am used to and like.

If the horizontal spread on the groups is larger than the vertical spread, then I'd blame the wind. It's hard to shoot good groups with a stiff trigger.

Yeah. It was the horizontal spread. Decided I would save time and rounds and try again on a sub-5 mph morning.
It has the Adjustable MOA trigger. So I will tinker with it a bit and see if I can get it to where I like.
