#Load data subsonic 223 pdf

This uses the same 100grn bullet but uses 8grns of powder and a small foam filler. You can achieve about 22 hornet levels, with just about any bullet weight. 223 and 50-55gr bullets I would start at 4gr N310 and reduce the load until you're subsonic / happy with. I have safely tested up to 6gr N310, so no safety concerns in the unlikely event that I double charge a case. I use 3gr N310 with an 83gr cast bullet (about 980fps) in my 6x45 (6mm-223). I seriously doubt they would cycle an AR. Vihtavuori N310 is a great powder for this. Powder (25grns) looks like Vihavouri.Д®S also produce a round that will not cycle the action- different folks like different things. Misc posts on forums regarding subsonic 223 loads (with some data on Hornet mixed in) I have used 700X for reduced loads in. Accuracy is adequate for it's intended mission out to 100m or so.Д«ullet is filled with Tungsten carbide- so not cheep. Has cycled reliably in all the rifles I have tried it in- 1960's vintage M16, Current M4, HK 416 and ruger Mini 14.Д«ullet (on the new stuff) weighs 100grns (old was 127grn) which is marginal on stability. Out of 16' barrels like our test HK 416's.it is often just supersonic (1180fps) but a few civi spec 16 barrels it stays just below the speed of sound.

6.5 Creedmoor 130gr CX PDF 6.5 PRC 130gr CX PDF 6. A 22lr of 40gr traveling 1280 fps makes 145.49 ft lbs, that's about 2/3's of the energy of the slower 223. Using 55f the bullet would need to be below 1112.08 fps, and I've found a 1:9 can stabilize a bullet of 73gr making 200.42 ft lbs of energy.

Occasionally, we will temporarily publish load data on this page when a bullet becomes available and is not yet listed in the latest edition of the handbook. Bullet length, not weight, is what determines what twist is best. It is designed to be subsonic in a mil spec 14ВЅ' barrel- it is. Hornady Manufacturing Company develops and publishes reloading data for the Handbook of Cartridge Reloading. It works as advertised within a narrow window.
