Re: WTB:Remington 700 7mm or 300 saum
You have specified Model 700's but most of the SAUM chambered rifles were Model Sevens and those are usually fairly easily found on Gunbroker or Gunsamerica. I see them fairly often.
I have a couple Model Seven SAUMs but none are for sale.
The Model Seven Stainless models with the tupperware stock had a "magnum contour" on the barrels and these are great shooters if you can find a McMillan Alaskan Wilderness Rifle Stock to fit on it.
If it's long it can't be wrong... LDHunter (Long Distance Hunter) from the Piney Woods of NW Florida. I hunt clearcuts for scrawny whitetails... ;)
