I have just started loading for 223 rem. that will be used in my AR-15. My question is that I have found load data in several places for H4895 under 63gr. sierra SMP but non of them state minimum COL. I am new to reloading for gas guns and not sure how short is to short. Any responce is greatly appreciated.

VC,
Try the Accurate Arms reloading manuals they list the "tested COL" or I believe Hornady lists minimum COL's for the different calibers. You may also want to look into a taper crimp for this in your AR.

V_C,

This is from Modern Reloading by Richard Lee.
223 Rem, Sierra 63 gr over H4895
Max COL; 2.260
Min COL; 2.165

I`m not sure how the Min COL is arrived at as it changes some due to bullet, or in other cases powder. I am thinking [Eek!] [Eek!] it is related to how the bullet depth affects chamber size in relation to powder vol but I`m assuming and you know where that gets ya.........
