While recently at the local sporting good store buying some rounds for my somewhat tired Win. 70 .270, I noticed in the rack a 7mm rum sendaro sf. My model 70 has been a great and accurate rifle for a long time, restocked, and misc. other things, by my dad who is a fairly accomplished smith. We both recently joined a club here that has a 1000 yd range which is really intriguing. Pops says I should pick up a Win. 70 super grade in .300 wm (he's a Winchester guy though to his boots) but I see a lot written about the sendaro here and elsewhere. The store only has the one and it is on sale for $650. Is this a good alternate to the .300. wm, I am a little taken back at the loads and pressure the 7mm takes. Comments?
