[QUOTE="65WSM, post: 1577180, member: 9551"] The suggestions of the 7 SAUM for a 500 yard elk rifle with 26 inch barrel I would consider minimum. The 6.5 short maganums are great for big mule deer at range but I think it is best to have energy on your side at 500 yards. The rule was 800 foot pounds for deer and 1200 for elk, and that isn't a record size bull. Your 30/06 is a great cartridge to reload but it is best inside of 350 yards and you need to have an action that will allow you seat the bullets out. I think a 24 inch barrel is also of merit for a 30/06. A long range rifle will weigh around nine pounds or more with bipod, sling, scope and rings. You might pay more for the glass than the steel. Stay away from cartridges that have to have the bullets deep seated and have short necks. [B]Choose a cartridge by its neck and the available sources of brass[/B]. Necks in 6.5 or 7mm should be a maximum of 13 thousandths wall thickness but not less than ten thou. Most brass is thicker on one side of the case. The full length of the case. You can turn the thick side off the neck but do not expect 500 yard accuracy out of uneven brass. I recently purchased some "Sig" brand .22/250 cases.
