The 40x will always hold a huge spot to me. I no longer have one but. It was the first accurate rifle I got, 22br. Had only had factory hunting rifles, I am all self taught. Got it, already had necked down 6br cases, of course they won't chamber, no internet, no cell, takes me a week to get a hold of custom shop, the give me a dimension for neck, excited to see what is up get home to realize they have me 6br. More calls to try to get them. Search magazines for gun writers and something that tells the town there from so I can call information in hopes of getting there numbers. Get a couple they help, also tell me to call Sinclairs, and get precision shooting magazine. Both a big help. Learn what neck turning is and read lots of other books. Finally got it working and it shoot really good. It made me learn quick and was very educational........... and cost me lots more money in my live of accuracy
