250 gr. Sierra GameKing

Here's the deal... I have been working up a load for my 338 RUM with the 250 gr. NAB and have been getting good results with H-1000. The only bad part is, (1 they're a bit pricey and (2 I can't find them anywhere! Elk season is approaching very quickly and I need to get my act together. I'd like to stick with 250 grains, so the GK has caught my attention, but I have a few questions before I go that route:

-How is the on game performance? (Looking for something with high weight retention)

-Should I be concerned with a slightly lower BC? (As advertised, GK is .565 and AB is .575)

-Will they fly as true as other bullets with hollow points and plastic tips? (1,000+ yard shots will be common whether it be big game or steel)

-Will they deform in the magazine?

Re: 250 gr. Sierra GameKing

I think they will flatten slightly in your magazine but not too big of a deal.. the difference in BC is negligible. and should be very accurate. I dont know about killing ability, but I bet they work well.

Re: 250 gr. Sierra GameKing

IIRC (& please don't quote me on this!), the 250 GameKing had been the go to .338 Long range bullet for a long time as it was the only high BC projectile that was game proven & readily available. The newer versions out there are starting to displace the GK as it is "old school" & not as shiny! Non-bonded, no polymer tip.... but as a long range bullet, I think you will do quite well with it, I wouldn't want to punch a moose or griz @ 75yds as I don't remember it being designed to put up with RUM velocities. It could definitely deform in your mag, one of the MAJOR down sides to the exposed lead nose... might go single shooter with this one.

I'm no expert on the GK, just things I remember (or think I do) reading/hearing about it.

Re: 250 gr. Sierra GameKing

I did some reading on it last night and you are right it was not designed for the RUM velocities it was designed to be a super heavy duty 338 win mag bullet. I am sure people were wildcating it at 2900+ velocities though. I would like to read about that and see how it worked... I guess me and Tom are gonna have to play with it and see what it does.

Re: 250 gr. Sierra GameKing

I have shot it since it came out in the 70's. It was the highest bc hunting bullet made for nearly twenty years by major manufacturers. It was still one of the best choices as late as 1998 when I designed the 338-300 RUM and many guys shot this bullet out of it. To my knowledge the first elk ever taken with the 338-300 RUM was killed with this bullet. It was designed with a stronger antimony lead core and a heavier jacket than most game king bullets. It will take down elk with no problem. I have shot it long range since the 70's in cartridges from the 340 wby to the 338-378 wby velocities with good success. I would not hesitate to load one up and go elk hunting right now.

Re: 250 gr. Sierra GameKing

Thanks for the info everyone. I ordered a couple boxes through Graf & Sons. They'll be here tomorrow afternoon so we'll see what happens.

Can I use the same powder and charge as I did with the 250 AB or should I back down a little and start there?
