I'm hoping someone may be able to shed some light on these. I can't find a match to what these bolts are for. The rim diameter looks to be about .430. Each bolt has a proof mark on it. The firing pin looks very familiar, but I cannot place. It reminds me of H&R, Mossberg type, but I found no match for it. Does anyone happen to recognize these bolts? I appreciate any info.

Well, I sure am stumped. But, have you considered perhaps contacting the folks at Numrich and asking if they can provide a clue? I know that suggestion is kind of out there but what do you have to loose?
The bolt sleeve is like Remington Targetmaster 510 but I don't believe it's a 510 bolt.

Those look like a old 410 shotgun bolt but don't remember manufacturer. Could have been mossberg
They very much have a Remington vibe to them, but I'm not seeing any obvious matches in the pics of my "Standard Catalog of Remington Firearms" book.
It's not a 510-Series (I have those imprinted on my DNA), but the general layout of head/handle/shroud, plus the plunger that drives the firing pin is very similar.
I THINK it's French. The proof mark section at the back of the Blue Book shows a "PT" underneath a three-pointed crown as being a French proofmark for smokeless rifles since 1900. The crown shape doesn't quite match yours and there isn't anything matching the crossed. . .lightning bolts?. . .that you have underneath it. All I've got.

In part, from post no. 2 ...
The Crown over PT means it was proofed in St Etienne after 1923. That is the final smokeless proof, and the gun was proofed at 12.090 psi (which is NOT very much).
Those four jagged lines, which look kinda like (but aren't) lightning bolts, mean, "For guns in finalized state when proofed - mark added to '39 or '40", so it was made between 1923 and 1939 or 40.

MinerJohn,
Just an idea, but with the .430" rim diameter and the French connection; could these bolts be from 9mm garden guns? I'm not at all sure of the rim diameter of the 9mm RF shot cartridge.
