[QUOTE="AZShooter, post: 2183751, member: 5219"] I feel there is too much emphasis on worrying about a longer bullet impinging on powder space. Get the cartridge to fit and feed from the magazine regardless of bullet's seated depth in the case. There might be a tiny loss of velocity in some situations. It is not a big deal. I posted a pic many years ago on this site where I seated a 230 gr Berger in a 300 WSM to fit and feed from a 2.8" mag box on my friend's Browning A bolt. Even with this long bullet buried into the case it still got 2735 fps in a 22" barrel! We joked that the bullet's base was sitting on the flash hole. My late friend Don shot his last elk with that combination and at 300 yds it flattened that cow elk! As stated by previous poster, the modification can be done to your Rem's mag box via the Wyatt's mag box for a longer OAL. I did that to my 300 RUM in a post 64 model 70. To further enhance accuracy capabilities a custom reamer can help. You decide the jump to the lands, throat angle, chamber neck dimension etc. Personally I own 15 reamers which were spec'ed out for my needs. IMO only way to go. In my experience most bullets can be made to shoot accurately without them kissing the lands. The notable exception is a Berger VLD. They can be finicky. Berger suggests four seating depths which are quite far apart to see how your rifle will respond. While true that a VLD will generally shoot well close or into the lands, they can be made to shoot with a significant jump too. It can be a pita but it can be done. A easier solution is not using VLDs but if you must use a Berger then use one of their hybrid designs. They tend to shoot well with just about any jump to the lands. [/QUOTE]
