After reading all of these posts, it appears most of you agree, it's not necessary.
3 weeks ago I ordered a Savage Model 12 LRPV with the dual port. Left port load, right port eject. I had to have it special ordered since it's not listed as a stock item anymore. As much as it costs, I want to insure I do everything I possibly can to insure I wring highest possible accuracy from it. Mine will chambered for the 22-250 with a 1 in 9 twist. Effie in the custom shop at Savage said the expected delivery date was 6-8 weeks. That was a shocker for me, since I expected 6 months or more.
Lord, I'm gonna have over $2400 in this setup by the time I have a base, rings & a scope mounted.
