Started working up a new load for the 50gr as I have used up all my 55gr and found that 0.050 jump works best in my .223.
Measured 2.0085" with the O.A.L. Gauge on average for 10 projectiles and seating them now at O.A.L. 1.959". Node seems to be 25.0-25.2gr so load them with 25.1gr of H335 which gives 0.4 MOA groups at 100m. Haven't checked speed yet...

HeadHunter..sorry didnt see your post until now..... I load to mag length..... another method that works for me is grab a loaded round that groups well in your rifle,set your bullet seater using that one and try it for fit in mag then chamber..... havent had a failure with that method yet.
