Joel,
I don't remember, but I doubt it. I probably just threw it on a Bruno's order because it was there. To the best of my knowledge I've never ordered a ratchet. I had the barrel setting around for a couple years then had it chambered up for use as a varminter and to see if it would shoot............then this 600yd match came up with its 17lb weight limit and I just put it all together, rebalanced to rifle and took it out to see could I get it to swap bullets at around 2900............I found my recipe at 2800 with the long floppy barrel but I found that I could run 'er up over 2900 easily so I went clear up to POP! I was just looking for a "node" or pattern of some sort. (Actually I was looking for slower bullets to be printing higher at 350 yds......)
I'll try to find an invoice.....
Hey! Can you SEE ratchet rifling? I've never looked down the bore.
