Since there is only a single .222" 40 grain bullet left in production (Hornady's) for the 22 Jet, some reloaders will use 40 grain .223" and .224" bullets intended for the 22 Hornet (the velocity envelope for bullet expansion is very similar). As long as you are careful to develop a load starting with the given minimum safe powder amount, the larger diameter bullets don't cause problems. Just loading up some cartridges with the listed maximum for a given powder and then using .224 bullets on top is NOT a safe practice. Trying to use lighter or heavier bullets is a problem due to the lack of published data. Most 22 Jet cartridges are fired on Model 53 revolvers and the forcing cone helps to smoothly swage the bullet down to fit the barrel without giving any extreme pressure variations.

one other thing with a jet - make sure your cases and cylinders are dry and free from oil jets had the habit of wanting to back out of the cylinders with that taper on the case if the cylinders or ammo was a bit oily, having everything seemed to solve the problem
According to the lyman reloading manual(#45) here are some loads for you. As ststed use only .222 or .223 bullets. Sierra makes in .223 a 40gr and 45gr bullet if you need any. Using 2400 powder-11grs=1365fps. Using 12grs-1937fps. Now these loads will be for the 40 gr bullet. Next is SR4756 powder. 5.0grs=1145fps,and 6.7grs=1524fps. IMR4227-11.0 grs=1575 fps and 13.5grs=1842 fps. hope i helped some. vangunsmith
