I'm obsessed with the 25 WSSM, its a good cartridge with performance falling in the 257 AI - 25-284 neighborhood, so what's not to like? I would love to find a Browning Ti Mountain Rifle in 25 WSSM for a price that I could justify.
What's not to like? Ammo and brass are obsolete and getting factory replenishment is a once in five year event. One factory ammo offering exist (from Winchester). Ballistic performance may be great, but it doesn't do you any good if you can't shoot several boxes of ammo a year without it costing a fortune. For me, life is too short to spend time scouring the world for ammo/brass at a premium; maybe others enjoy the trill.
You should feed your obsession and offer to buy this guy's rifle
