I just picked up a used Tikka 595 stainless synthetic .223. Included in the sale was about 250 cases, 140 36 gr. varmint grenade, 75 52 gr. Sierra HPBT and well over half a pound of H4198. Not being a reloader enthusiast, I picked up a Lee classic kit ( it worked out well for my .270 ) and 200 small rifle primers. Could anyone give me some info including O.A.L. for this bullet powder combo, or a different powder? Thanks to all who respond.
