I got rid of my 1st 260 cause it had bad juju. I got a new one that shoots like a dream. NO load workup, just picked the "most accurate load tested" out of a manual and shot a 3/8" group at 100 in 32 degree weather. I know I'm slower than 2830 as my buddy's dope is a lot flatter. I was told the 260 is really quirkey. I'd like to go faster but should I just stick with this load? What about trying to do a load workup in warmer weather n push it faster?
