[QUOTE="Bravo 4, post: 1306184, member: 8873"] TC338, What is your barrel twist? My .308 is 1-12" and at almost sea level I can only go up to around 200 grain matchkings before I start to get other than perfect round holes at 25 yards with sub loads. Not good for a can. My loads from 150-170 grain round nose are from 10.5-13 grain of trailboss. I have tried stuffing as much powder as I could behind a bullet (without getting too ridiculous as far as compressed) and couldn't get enough in to cause any pressure. Unlike how most folks develop a standard (supersonic) load, DO NOT start low and work your way up! Start high and work your way down with TB sub loads as you don't want a bullet to stick in your barrel, been there and it sucks! I have also drilled out the flash holes with TB loads and from what I can tell it made my velocity increase a little and also dropped the spread a bit. [/QUOTE]
