For the sake of kick it back and forth argument fun, here's my chin scratcher.
I need affordable, extremely durable, stainless synthetic rifles in 7mm Rem for my outfitting operation. I'm getting more hunters requesting a loaner rifle, the 7mm mag is a no brainer here as guides need to be able to grab ammo at home hardware on my behalf in a sleepy town. Need as flat of shooter as possible for a long zero on mountain goats and reasonable recoil, with the ability to hunt Grizzly without much concern. 7mm Mag's the end of that story so it's all about the rifles.
Right now, I've used a Kimber Adirondack .308 for the purpose, but it's too light on cartridge and trajectory. Also would like to have two of these loaner rigs and keep them the same. Weight, and cost are the primary concerns, but they can't be a Savage or the like. You just can't put one of those into the hands of a guy paying for an experience. I'm going to use one as a work gun plenty no doubt too as they'll already be there and iron sights would be a big bonus.
Considering, all in stainless,
-Ruger 77s (they also extend an outfitter discount, but likely buying used anyhow)
-Zastava Mausers
-Winchester 70's (likely it)
What would you pick? What am I neglecting to look at? No Rem 700s don't want that safety behind me, one thing in a guy like Douglas' hands but when I don't know the fellow I'd rather a good three position I trust.
It would be hard for any self respecting rifleman to cast dispersions on a M-70, and an outfitter's loaner (rental) rifle, should be a quality piece, appropriate for the conditions in which its going to be used. Since this piece of equipment is used to generate revenue, it doesn't fall into the same category as the type of rifle usually envisioned as a loaner. So while price cannot be ignored, neither should it be the primary consideration. A rifle that can have parts replaced easily in the field is superior to one that requires specialty tools and a machine shop. A Mauser extractor can be replaced by anyone with strong fingers, not so a 700's, but you should have a spare parts bin that includes springs, floorplates, extractors, and bottom metal.
What I'm suggesting is a semi-custom rifle, that suits the specific conditions your clients will face, better than an off the shelf rifle. If you started with a stainless M-70, you could install a glass and pillar bedded fiberglass stock, that is more resilient to hard use than are typical factory stocks. A spacer system for the butt would allow for variations of LOP, not a bad idea since clients come in all shapes and sizes. If the barrel is shortened to 22" from 24" makes the rifle just a bit more compact and improves handling in the thick stuff, without seriously impacting velocities. Or you could start with a .280 rather than a 7 mag, since standard chamberings often come with a 22" tube. Aftermarket irons, perhaps an XS, or NECG ghost ring and a rectangular post in a barrel band front sight, are superior to factory irons. The action should be polished to reduce the degree of difficulty in lifting the bolt handle. QD rings that are proven repeatable should be chosen for a rifle when the client might be required to switch between optics and irons and back again, and there is no opportunity to re-zero the rifle. The optics should be compact and durable, and be suitable for short range and longish; perhaps a 1.75-6X a 2-7X, or a 2.5-8X. A Pic rail base resolves the difficulty of mounting a short tube scope on a long action rifle, and to a degree allows the client to optimize his eye relief.
Specific rifle ammo should be purchased in sufficient quantity, prior to the season opening, rather than sending the hired help out at the last minute to choose ammo from the limited selection in a small town hardware store. The loads should be appropriate for the game being hunted, and the conditions involved. A 140 gr AB might be just the ticket for goats, while a 175 gr Partition is arguably a better choice for big bears, or whatever equivalent you can acquire in factory fodder. I suppose you could split the difference and choose 160 gr Accubonds for everything, the point is that there should be a quantity of standardized ammo on hand for those rifles.
With respect to the type of safety chosen for a client's rifle, I would rather he just didn't use one. Insist that the rifle is carried with a full magazine and an empty chamber. After the shot(s) been made, check yourself to ensure that rifle once again has a full magazine and an empty chamber. If the rifle is carried cocked on an empty chamber, it cycles easily when a round is needed. If it turns out the striker has dropped prior to loading a round, you don't want that guy behind you with a round in the chamber, safety or not, so it doesn't really matter if the safety is a 2 position or a 3.
