2023年8月23日 · I’ve been looking around for some load data for 5.56 69 - 77 grain bullets. Specifically for 556 pressures not 223 Remington. I’ve been looking around for load data on this, but it seems that most people provide 223 Remington data, which is …

2010年1月22日 · Re: .223/5.56mm load data 77gr SMK I am getting 2780fps with 25.8gr of Varget in a 20" wylde chamber with no pressure signs. The same barrel on the same day gets 2830 from TAP 5.56mm which I am trying to duplicate.

2017年12月22日 · I have shot the BH 77gr otm, IMI 77gr and the Magtech 77gr through 3 or 4 gas guns and my bolt gun. Of the three the BH is the most consistent and accurate. The IMI and Magtech group about the same, usually .25 worse then BH. The IMI runs hotter then BH and the Magtech is close to the same as BH.

2020年3月1日 · IMR 8208XBR is a good powder choice for .223 / 5.56 loads as is Ramshot TAC in my experience. TAC is plentiful currently but 8208XBR is shipped in from Australia and is very scarce. Mid South Shooter Supply will allow a back order and should be able to fill it in 1-3 months. They just fulfilled my back order today actually.

2023年8月7日 · Black Hills 5.56mm 77 Grain Tipped MatchKing Accuracy Evaluation Update In 2016 I posted an in-depth review of the Black Hills 5.56 77 grain Tipped MatchKing ammunition. Three 10-shot groups of that 2016 lot had an average extreme spread of 1.26”. The smallest of those groups had an...
