I see "Swiss P 5.56x45 SS109 Black Round 62 Grain Full Metal Jacket(FMJ)" at decent mail order prices and I wondered if anyone have any experience with it. I want to try a higher weight than 55 and also don't want green tip since I will be sighting in at an indoor range.
Rifle is 1:9 18" so I might get better long range accuracy than 55, but not sure and want to test.
