Have a Remington Hepburn rifle in this caliber, built by Sedgley in Philadelphia back in the 1930's. It belonged to Dad but now it is mine. Dad used it in Bench rest 100 & 200 yard matches back in the 1960's Probably has not been fired since until I took it out a few weeks ago.
Got some reloads with it. Seems to group nicely once I got the Unertl scope dialed in. It was originally chambered for 22 Hornet and then rechambered to 22-3000 G&H. The reloads used 2400 powder , some had SISK brand bullets and the others had some SIERRA 22 Hornet 45 gr SP.
Best part is got a lot of brass , some bullets and reloading tools with it. Not a bad looking piece.
Anyone here have any experience with this cartridge ?
