Re: 300 RUM or 338 RUM?? Which and why???

I read that the 338rum was made shorter due to the tip to ogive length of the 338 bullets being loner than the 308 bullets. This combined with the need to still fit and function from the magazine length of the remington rifle required a shorter case length.

If you fire a smaller diameter bullet down a larger bore, it just skips off the rifling and will have no accuracy, now if you fire a larger bullet down a smaller bore...

    I also read the same in an article by Jon R Saundra when the 338 RUM was first introduced. By shortening the case, they could use the existing cannelure.

    Tang, I dont think anyone was arguing with you. I know I wasn't. I dont know for sure why they did what they did. It's just what I heard. But since you bring it up why did they make the 375 case the same as the 300 and 7mm?

    I had a guy at the range talking to me and loading magazines for me, for a Ruger KP90 .45 ACP. He loaded a .40 into the mag. The extractor claw held it and fired it. It split the case down the side, I still have it...lol

    I think both would make excellent long range rifles. With the 300 I would probably use the 210 bergers and that would be a great round. I am afraid I will miss the 250 and 300 grain bergers that are coming out for the 338. The 338rum with the 250 vld would make for and absolute excellent set up. I think but than again thats why I'm asking you guys
