@Synthetic A useful alternative is the 77 grn Sierra Tipped Match King which are designed for the shorter AR type mags. They perform well on deer.

Not wanting to hi-jack this thread about Gimp's excellent rifle that Greg put together, but Ive now tried these 77 grn Sierra TMK at Tikka mag length (2.300") with a reasonably stout load of 2206H. 2900 fps from 22" barrel. Very good groups. Prospects are looking good.

@Synthetic, look up waters rifleman magazines sold over here. He makes and sells tikka .223 mags in a range of lengths up to 2.6 inches specifically for the 80 gn projectile loads.
