Ha! I was hoping nobody would notice the reference to the 35 gr. Vmax. Yes, it is .224", which I'm sure will get me "beaten from the fort." As you all know, the Jet generally utilizes .222" or .223" bullets. I have several boxes of each left, but having once run out of bullets in a different context long ago and far away, have developed something of a hoarder's mentality when it comes to bullets, powder, and primers.
Both Kent Bellah back in the day, and Brian Pearce more recently, have said that SOME Jets can digest .224" bullets. The test, according to them, is to measure the chamber throats by attempting to insert a bullet from the front. If the throats will accept the bullet, you're probably good to go. So I did, and it does. Lane Pearce (sic) wrote a column in Shooting Times wherein he referenced a Sierra "data sheet" on the Jet utilizing .224" bullets. He went on to say that if you can slip a .224" bullet into the neck of a case fired in YOUR gun, you're GTG. Notice that Lane said that, not me. Notice as well that the 35 Vmax with the blunter ogive was intended for the likes of the Hornet, so the jacket is thinner. So I commenced to experiment cautiously, and I stopped when I got 1650 fps chronographed, and it works fine. But that's just me, and my gun, and I absolutely do not recommend anyone else try it.
