Re: Need input for the ultimate pack in rifle (IMO)
For a lightweight packing rifle I would go 300wsm or 300 wby without the break. If you truely want a light packing rifle then either one would let you drop the break. This will drop a few ounces from the rifle, also depending on which break you get/have you will likely need hearing protection, another thing to pack along. It depends on your type of packing...how far/how much elevation/trip length...That being said I fell for the 300rum too, but mine is too heavy for a packing rifle in my neck of the woods.
I think you will be able to reach out a grand with a 300rum, I am just getting started on the over 600 yard paper punching with mine, and it seems to like 200gr accubonds with 95.5gr of retumbo, rem brass, cci mag primer. I use a rubbermaid bin container full of dry news paper to test penetration, and the penetration is pretty good at 600 yards, but I haven't had a chance to try it at a 1000 yet. I managed a 5 shot 9.5 inch group last weekend at a grand, but I am sure I can tighten that up with some time...
It sounds like you will have a very nice light longrange rig when you are done. Going to post the pics when she's ready?
