[QUOTE="Kennibear, post: 948541, member: 51650"] Before I sold them to move to WA I loaded for a couple of M16's and a MSR (still have the MSR). Use a small base sizing die every time. I switched to a Lee FC and have never looked back. If I feel the need, I buy a Lee FC in that caliber but I should point out I do not crimp unless absolutely needed. The Lee will crimp too short and too long cases with the same setting. They can be set to just turn back the neck into an un-cannelured bullet removing any case flare. Just remember that the MRS's ram the ammo into a feed ramp pretty aggressively and that will jam a bullet back into the case. That can raise pressure a bunch! Although I shot DCM matches with smooth sided 69gr Sierra MK's I load cannelured bullets if they are available in the style I want. Nosler especially runs batches of their bullets with a crimping cannelure. I trim to 1.752" as the Lee trimmer setup cuts that length. It takes about four reloads before the cases need to be re-trimmed. I find H322 about ideal for any bullet under 60 grains and even the 55gr FMJBT bullets shoot well past 500 meters. Enjoy your MSR's. KB [/QUOTE]
