Hey all new to the blackout world but been doing shooting for a while under real time conditions and ballistics effects. I have a question concerning handload of 300 with reman'd LC brass running IMR4227,WSR, and hornady SST 125gr #3019 for coyote. I have looked up ridiculous amounts of info on this but seen both sides. Anyone in particular ever used this combo starting with 16.5 gn to 16.8gn? Second is 147gn cannelure FMJ milspec 308 using same confiuration? Platform one is great lakes upper with yankee hill 16" 1:8 twist heavy barrel with yankee hill slant brake and carbine length gas impingement with yankee hill gas block.Platform 2 is Ruger mini 14 for 300AAC non modified. I have seen alot discussed but have a huge COAL value and all cases trimmed according to wilson 300aac case headspace gauge. Any help that cou;d be provided to narrow down what I have found would be awesome.

I have tried 4227 early on and altho I have some super accurate loadings with middle weight bullets. I have mostly moved to other powders. Mostly because of the speed attainable.

if its what you must use you should be able to find some good loads. But they will not reach top attainable velocities.

Let the fun begin, good luck!

Isnt it amazing how much Ed Harris uses Bulleye on everything and gets by with it????

AS a newbie to the 300blackout I have a lot of questions about sub load and supersonic loads
h110 has always said not to decrease load more then 3% and seen several loads listed as much as 12% reduced?
shooting 16" heavy ar15 threaded for can, figured two uppers cheaper then two rifles

enlighten my mind plz

Is there any info for vv n310? Wanted to try some with 168gr bullet but not sure where to start. Was thinking 5gr and work down from there but don't really want to be guessing with a powder like that.
