Re: 40 - 55 gr 223 Rem.....
Weatherby vangard/Howa 1500 20in 1-12 w/Timney trigger (this is a must for a Howa 1500) 40gr Nosler BT 27.3grains of Benchmark 2.26 oal, 50gr. Nosler BT 25.5 grains of Benchmark 2.26 oal. Will shoot the 50's .5 but will shoot the 40's at .3 all day long.
I started out thinking the 50's would be as light as I would shoot and it shot them pretty well about what I expected from a $430 new gun but then someone suggested the 40's and it loves them. Much better results than I expected from a cheapish gun.
I have a LTR in 223 that so far won't shoot any better but I have to admit I haven't spent nearly as much time with it as I have the other.
I've never tried 40's in my 1-9 LTR my initial guess is they would blow up. Anyone try any 40's in the faster twist 223's?
