Oh I forgot to mention fire forming brass does not bother me either.
Kreiger#2 25inch barrel 1:8
Wild cat light weight stock no bottom metal to keep weight down.
rig to be 6lbs when done 6.75 scoped.
What caliber do I choose? , I have a custom 260 Rem right now and it is awesome but I want more punch for the elk at longer ranges .
Ramrod....I would STRONGLY consider my new 6.5 SS, especially since you mentioned that you don't mind fire forming! It is based on the SAUM case. I designed it to fit in a std. Rem, or other magazine, with the long bullets. It is the same length to the shoulder/neck jct. as a Creedmore but holds 71 grains of H20 with the improved design. I use 300 SAUM NORMA brass which is available and excellent quality. I shoot a 26" barrel on a Rem SA and get 3200' with 140's and have shot the 160 Matrix at 3050'. This is one flat shooting, long range round with a b.c. near .700 with the Matrix. I can get custom dies from Whiden in two months or less which are top quality.
This cartridge has a .320 neck, which is far better than the others that have been mentioned, and barrel life should be very good given the long neck and 40 degree shoulder which keeps the flame point inside the neck better (rather than directly into the throat) like the short necked .284 for example. you can load with very mild pressure and still out do the 6.5/284 by a considerable margin when it is loaded to top end!
