Light primer strikes on reloads

[Dogleg]

How would seating the bullet into the lands cushion the blow? Full length sized with the shoulder pushed too far back will absolutely create negative headspace and consequently light primer strikes, but a bullet seated into the lands should negate that and create positive crush fit.

Simply neck sizing and not bumping the shoulder back more than absolutely necessary will have the same effect, but you lost me on how seating the bullet deeper at that point will have any effect.....

To the OP, when you drop a resized case into the rifle (just the case, not full of powder etc) is there slight resistance on the bolt when you close it? Or does it feel like you are closing on an empty chamber?

Control the factors you can, and reap the benefits with every shot....

When you have a jam fit to the lands the firing pin strike tries to drive the bullet farther into the lands, much like driving a tent peg. You aren't going to get the same whack as a case head-spacing on the shoulder which is considerably better just because of the larger area. If you push the shoulder back "too much" it'll headspace on the belt. You can't get a better hit than headspacing on the belt.

Isn't that what I said?

Time to chime in, and possibly hijack the thread. Lol.
2 weekends ago a friend and I went to the range, it was time to fire the reloads that I had been concocting. Needless to say his 5R had 3 misfires with my reloads, so I put them into my rifle 700aac-sd. 2 of the three fired without issue, one still remained. We packed her and n for the day and when I got home I pulled the bullet apart. The powder was not burnt (obviously) it was a proper charge. I removed the primer and took a look at it, it was struck and hard so I then took a few safety precautions and using a 4lb mallet, I struck it against concrete. Nothing happened so I tried it again and it "snapped", has anyone ever had a primer that was this hard to set off? Also we need to use the micrometer on the 5R firing pin to make sure it's not a lil short.
