[QUOTE="Long Time Long Ranger, post: 312772, member: 505"] I am with you 100% on all you said. Gamekings in 30 cal and smaller have way to thin a jacket and to soft a lead core for anything other than deer. Starting with the heavy 8mm gameking and the larger calibers Sierra uses a much tougher antimony lead and a thicker jacket making it a top big game bullet. I have used the 338 cal 250 gameking on elk to over a 1000 yards since they first came out with it in the 70's. It was for a long time the highest BC big game bullet on the market. The perfect fit for my new 340's and 338-378 wby's in the mid to late 70's. It is still a top big game bullet for elk. I also think the 225 AB is the right choice over the 250 AB because there is not enough BC gain per velocity loss. Most of the 338-300 ultramags I did top out just under 3400 fps with the 200 grain bullet with best accuracy and any kind of brass life. The 225's between 3250 and 3300 fps. These are averages and what my two personal guns do. The AB is a tougher bullet than the 215 gameking but either will take elk. Now I shoot 225 AB's in my 338-300's. For me they give the best BC/velocity ratio in a quality big game bullet I can count on in any shooting angle circumstance to take game. With the ultramag size case I prefer these to the 300 matchkings. They shoot much flatter and have way less recoil in a hunting weight rifle than the 300's. I would not have a problem taking an elk at 1000 yards with the 225. If I knew I had a shot beyond 1000 yards I had rather have the 300 but you got to play the averages of where most of your shots are going to be. But if I know I will have shots beyond a 1000 yards I will carry my 338-378 or 338-416 IMP and push the 300 well over 3000 fps to get an edge way out there. But inside a 1000 yards the 338-300 ultramag is incredibly accurate and has way less recoil than my 130 grain plus powder charges in the big guns so I like it. [/QUOTE]
