Hello, I'm new to your site here and would like some help... Received my first Weatherby Mark V .257 this afternoon made in Germany in 1961. I believe it to have a 1-12 twist barell and want to handload some accurate bullets for mostly Whitetail or Antelope hunts at this time... I've read some posts as these may not stabilize accurate loads over 100 grain bullets etc. But plan on loading some 115 Sierra Spitzers or 117 SST's And I want to buy some good scope rings and bases, maybe Talley in Gloss... Any suggestions guys?? Thanks Les
