Re: Nosler J4\'s DAVE KING please read...
I have shot a lot of J4's, both in Winchester Competition Supreme factory loads and in handloads. They seem to be easier to get than Matchkings from some of our suppliers. You can buy them in boxes of 250. In most of the rifles that we shoot the J4's are very close to Matchkings. Like your rifle we have some that shoot them slightly better, some that are not as good. We have checked for optimim loads and the J4's shoot the same amount of Varget as Matchkings, each rifle has its preference. A suggestion: give the Speer 168's a try, they are sleepers. You never hear much about them but they are also very accurate bullets.
Last year I shot two deer with the J4's and they seemed to perform like Matchkings, died in their tracks. Longer shot was 383.
There are several very good match bullets out there but I believe that the Matchking is still #1, particularly the 175 grain version.
