[QUOTE="Yorkplates, post: 102569, member: 3575"] I would say that over the past several months that I have learned quite a bit about action lengths, circumference, bolt face sizes, etc. and their relationships with certain cartridges. There is a little gray area that I would like to address. It is concerning the 257 Roberts. Why is it considered a bad idea to try and build this rifle on a short action? I understand that the 7X57 case, that it is derived from, is .2" longer that the .308 case, but the bullets that come factory loaded and even handloaded all keep The OAL shorter that my 168gr .308 Matchkings. The largest grain size I have seen is 120gr Nosler partitions. I'm looking at one now and it is shorter than the .308 mentioned before. My dream light-carry rifle would be my Kimber Montana in 257 Roberts with 110gr Accubonds. The rifle is chambered in 308 and I thought with an identically contoured barrel in 257 Roberts from one of the custom barrel guys, it would be a classy little whitetail slayer. It would even add a little more meat to the barrel, having a smaller bore. I just don't understand why it is a bad idea. The 120s fit very well in the blind magazine and seem to feed fine. I really would appreciate it if someone could clear this up for me. Clay [/QUOTE]
