Seafire,
When you say "Old IMR data" are we talking 1970's? 1980's? How would you feel about this bullet for big mulies or cow elk? Is it tough enough?
Thanks!
ttpoz....
I personally would choose another bullet myself... but many other people have success with the 85 HP in 6mm from Sierra....
I'd have to defer to them...
as far as IMR Old Data.... they last put their old Brownsheet reading info up thru the early 2000s, because I have a few copies that do list the 260 Rem, and have some of the older cartridges deleted.. I use to have a couple from the late 70s, early 80s.. but after a couple of moves... they disappeared to the winds....
but I do have several from the early 2000s with the 260 listed in it.
another great source of reload data is Steve's Pages...
http://stevespages.com/243.htmlthe site has almost all the data on most cartridges, right up to the time Steve passed away....
he was a member on the campfire here.... someone else is still maintaining his web site tho.
I consult it a lot, but as always, work up....just for safety sake.
best of luck.
