Your firing pin fall is more than adequate.

Pull the bullets. I'm interested to see if there's powder in there. 22 is a lot, but it can happen. Not sure how many you loaded at once.

Every time I think I have a bad primer, or mishap, I pull the bullets and find no powder. Maybe you'll find something different.

Edit: also if you weigh the cases you should be in the 265-275 grain range with 30ish grains of powder and 105 bullets IIRC, 230ish grains without powder. Still gotta pull them bullets though.

I went through this whole thing with primers with FTF and light strikes last fall and winter. Here's what I learned.

1) you can have adequate pin fall and still get light strikes if there is something inside the bolt impeding the speed or intensity of the drop.
2) CCI will (or at least they told me) that the 450's and BR4's MUST be set to bottom out in the primer pocket and be set .005-.007 below flush with the case head.
3) Excessive headspace will contribute to FTF and light strikes.
4) a bolt with excessive clearance at the rear of the action will cause FTF and light strikes
5) never assume that if the rifle is new or just came from the gunsmith or factory that there isn't any debris inside the bolt impeding pin drop.

And of course as previously mentioned..... make sure there's powder in the case, and I agree with the other poster that 250's, 400, and win SR primers are easier to set off, but there is something amiss if a Stolle is showing light strikes. JME. WD

I will pull them, however, I think you’re missing a key factor in this Mike.

The primers didn’t ignite. Whethere there’s powder in the case, or not, would be unrelated to that.

 

[mikeeg02]

Two more things

If the primers were not fully seated, that can cause them to in fact not ignite. It doesn't take much neck tension to hold the bullet while a primer goes off. When you pull them, they will be coated in soot if the primer went off and there wasn't any powder. Until you pull the bullets, were all just being hypothetical, and giving our best guess.

Firing pin fall on my Panda F Class is right at .240”...how do I increase the fall??

 

[mikeeg02]

Adjustable trigger hangar. The Hoover's say .250 is optimal on the Pandas.

Figure anything out?

Great people both on and off the range.

Can an adjustable trigger hanger increase how far forward the pin falls?

To adjust firing pin protrusion? That's not a function of the trigger hangar. That's inside the bolt. I haven't had to mess with my 700s, though I know on the savages you can adjust that easily.

.240" is enough, the smallest 10 shot aggs ever shot at 1k were done with .240"

Just a couple posts up.

 

[X-Caveman]

Using an adjustable hanger may increase pin fall, but it may also come at the expense of adding cock on close. May not be worth the trade-off. My $.02 is to measure & if below about .235” on a Remington style bolt, send it to a qualified smith to have it timed. A properly timed ignition is beautiful.

I don’t think an adjustable hanger can increase the amount of forward pin fall, as in making the firing pin come further out of the bolt face.. I may be wrong but can’t see how that can be achieved??

 

[Alex Wheeler]

A trigger hanger is the easiest way to increase pin fall. Pin protrusion is different.

Pin fall is the firing pins distance traveled from cocked to fired.

Firing pin protrusion is amount sticking out of the bolt after fired. As Alex said.

Edit: firing pin protrusion should be no where near .240 or .250 lol. More like .060. Depending on preference and spring rate.
