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?
