Just started loading for a 7mm RM (win model 70) that I purchased at an auction. It came with a box of old Nosler 150gr Solid Base Spitzer boattail bullets.

I loaded up some test rounds last night for load work up:
F-C Brass, trimmed to 2.490"
WLRM primers
COAL of 3.285" (0.007" off lands if I measured the chamber right?)

5 rounds each at 60, 61, 62, 63 gr of IMR 4350.

Now for my question: I did a search here befor loading and found a thread that had some data by hooligan that showed his COAL with Nosler partitions around 2.800". Doesn't that seem short to you? Am I making mine too long?
