G'Day Fella's,

Here is a bit of an update on the same/existing Nosler forum thread for this rifle (and some chrono details, of my .45 Colt revolvers).

FYI, I achieved 2500+ fps with most of these loads but they are definitely Maximum Safe Working Loads (MSWL), in this rifle. The exception, was the Speer 0.308" 130grn HP bullets, which went 2420fps.

The attempted Sub-Sonic loads 9.0 grn of Trail Boss powder and 124 and 130grn bullets, were still approximately 250 to 300 fps to fast. I'll try 7.5 and 8.0 grns next, and go from there........
