Wow.................flash back.
I used to have a classic English styled 7X57 I made for myself, but my brother-in-law beat me out of it.
I also used a fairly warm load of 4350 with the same Hornady 175 gr round nose bullet and got clover leaf groups from it too. The barrel was an original from a 1908 Brazilian Mauser I cut to 22" and turned the steps out of it. One of those "old surplus rifle barrels" that so many want to replace. If the bores are shiny you'd do well to give those old barrels a chance before you decide to replace them.
My current 8X57 is another one. It's so accurate with 170 gr Hornady SSTs that it is unbelievable. It was 29 inches long and I just cut it off to 19 and turned a nice taper to it.
I never took pictures of the best groups I shot with it, but I do have this picture of the target shot with the worst ones. These were shot with 200 grain Speer bullets and the 170 SSTs shoots[u]
groups 1/2 this size .
That's
groups too, not just one group. I've done it several times. So it's not just a lucky happenstance.
This old barrel really is that accurate.
