Hey KKook,
A bit of a hijack, but you may remember years ago, about the time I joined RFC, you helped me assess a Kimber of Oregon Super America the LGS had for sale here. It was a .22 Hornet, that I bought and ultimately sent down the road, but the rifle came with about 400 rounds of the original owner's handloads. I fired a number of those loads in the Kimber SA before it left the herd, and they shot exceedingly well. I didn't feel comfortable selling reloaded ammunition with the rifle, though, so I still have about 350 rounds left. It uses the late, great 45 gr Nosler Solid Base Hornet bullet with various powder charges, mostly 4227, all very well documented.
Anyway, here's the rub: I have tried to shoot that ammunition in five or six subsequent Hornet rifles. As I recollect, I tried them in a Walther KJS Target Rifle, a BSA Hunter/Regent, an Anschutz 1430, my scratch-built 80% Low Wall, and now, the ULA .22 Hornet I just bought, and none of the loads would even chamber in any of those rifles of widely differing manufacture. It wasn't even close to chambering on most. The rounds obviously chambered and shot very well in the Kimber, so, my question is, is it possible the Kimber Hornets of old have extra large chambers? I saved the ammo to use, but it appears I will have to pull all those bullets just to FL resize the brass to reuse it and the bullets.
Just curious, and, if anybody knows, I think it would be you.
Thanks
