Anyone here reload 257 Roberts? I've purchased a Savage 111 that I'm going to rebarrel to 257 Roberts for my children to target shoot/hunt with. I purchased some Winchester +P brass the other day. Up until now, I have not sorted brass by weight etc because I just like to go out and shoot. However, after I've been doing some reading on different forums and such, I decided to measure and weigh 10 random pieces of the brass from a bag of 50. Weight varied 2.6 grains (173.8 to 176.4), length only varied about 0.001". What bothers me about this brass is that the rim and head only measure 0.466". All of my loading books and reference diagrams that I have on the 257 Bob state a rim of 0.473" and head of 0.472". Now that's a difference of only 0.006" to 0.007" , but is this something that I should be concerned about? I don't have a ball micrometer yet to check the necks, but that is coming in about 6 to 8 weeks.

Does anyone use the Remington brass for the 257 Bob? What do your cases measure?

Any advice or comments would be appreciated.

Thanks, John
