Never, I tend to use Federal, CCI, Remington, Muron and Magtech with the first two being my preference

I ran some of my reloads yesterday. It was too hot really but I still tried a few loads.got to 62grs of N 165 behind a 180gr hybrid and started getting faint ejector marks.quickload predicted 2890fps on this load.not really sure how it works but 57.6grs of n165 in my 284 produces 2820fps when I last chronied.the 7mm saum with an extra 5grs more powder you would think quite a bit more fps not just the 70fps predicted by quickload

I did some ammo testing the other day and I didn't see the faint ejector marks in the bright sunlight.had them on 61,61.5 and 62grs of N165 which were more obvious.its a shame though as 62grs must of hit the top accuracy node with a nice 0.340 group.i ran some 60.5gr loads frew the chrony this afternoon and I was getting 2871fps with the 180gr hybrids. Not quite what I had hoped.maybe I will try the N560 then.

I had good results with N560 however it is heavy on the barrel and throat erosion can be measured every 50 rounds.
