I have been working on the forend and put in the O-ring. Went to the range this weekend to see what would shoot best in my handi ulta 223. Tried 55gr Rem soft pt, 55 gr. V-max, 55 gr Fed with Gameking (I believe), 62 or 63 grain soft point, 45 gr Rem hollow pt and 50 gr Rem hollow point. All but the 50 gr Rem were all over the place, 2 to 5 inches. Rem. 50 gr were touching. Tried them several times after shooting the others and every time 1 inch or less. Guess I found my ammo. Might try 50gr from another company just to see.
