This is the first time I have reloaded a belted cartridge and just want to make sure I am measuring the OAL correctly for this round. I am planning to start off with Nosler Ballistic Silvertip 140gr, Ballistic Tip 140gr and Ballistic Tip 129gr bullets. I am using a Remington 700 and came up with the following OAL cartridge lengths:
Silvertip 140gr = 3.326 to the lands, O.A.L. of this round 3.316
Ballistic Tip 140gr = 3.390 to the lands, O.A.L. of this round 3.380
Ballistic Tip 120gr = 3.355 to the lands, O.A.L. of this round 3.345
The Speer manual calls for a maximum cartridge length of 3.290. Should I back mine back to this length or use the actual measurement for this gun? What is the minimum amount of the bullet that needs to be inserted in the case? 1/4? 1/3? The 120gr bullets are only going to have about 1/3 of the bullet inside the brass if I use the 3.345 measurement.
Brass cut to length of 2.490.
I did find some of this brass was cut to 2.480, would this still be safe to shoot?
I haven't decided on a powder yet, but suggestions for these lighter loads would be appreciated.
Thanks in advance!
