Re: Federal Gold Medal Match 175gr Sierra Match King
I would buy a box or two and try it in your rifle before buying in larger quantities. I would also recommend trying several other match loadings in different bullet weights from different manufacturers.
You never really know how any given load will perform from your rifle until you shoot it.
A few years ago, I bought a Remington 700VS in .308 (26" barrel, 1:12 twist). Before I actually shot it, I figured that the specs of the rifle would probably favor 168gr match bullets. I bought and tested 168gr and 175gr match loads from Black Hills and Federal. All loads shot well, but to my surprise, my rifle showed a distinct preference for the 175gr loads from both manufacturers. It shot the 175gr Black Hills load the best. Consistently delivering .3-ish three shot groups time after time.
Bottom line, try a few different loads. If your rifle shows a preference for one specific load, buy all of that lot number that you can find/afford.
