[QUOTE="johnnyk, post: 456127, member: 307"] I got about 1200-1300 rds out of the first 7mm RemMag Sendero that I owned. The accuracy was still under 1/2" but cleaning took hours. Traded it for a 700P, same caliber. I don't see a huge difference in the two cartridges. .007" difference in diameter. The .270WSM holds 78.9gn of water, the 7Mag, 83.2gn. That's 4.3gns difference. Not alot of barrel scorching difference. JohnnyK. [/QUOTE]
