I had big plans to send my Remington 788 in 22-250 into ER Shaw and have a 1-8" twist barrel installed and have it chambered in 22-250 AI. I took it out of the safe to look it over today and that idea simply won't work. The ejection port is much too small and there is no hope of using the factory magazine for heavy 22 cal bullets. Eliminating the magazine and making a single shot would not be too difficult but I can't come up with a solution for the short ejection port. The factory barrel has a couple thousand more rounds than its expected lifespan and is time to go. Any obvious suggestions? I have no interest in screwing a boring 22-250 standard twist barrel back in. The 22 BR Remington might be an option..........
