Can't seem to find any data online for these, picked them up for around $27 per 100. I am not sure which powder to try, have some W760 and some IMR4831 on hand. Could I use data from Hornady, Barnes, Nosler, Hodgdon for a similar 80 grain projectile?

Nosler has data for 80 grain ballistic tip spitzer. 42 grain minimum load to a 46 grain maximum load with IMR4831. Is it safe for me to start with the same minimum and work up, taking all precautions and checking for pressure signs, I do not have access to a chronograph.
 
From the Speer#10 manual Win brass...80gr data...use mag primers with this powder........win760/41gr/2958fps 43gr/3095fps 45gr/3233fps
IMR 4831....80gr data........standard primer.........44gr/3086fps 46gr/3205fps 48gr/3344fps

Used some W760 in one grain increments, off to the range tomorrow for some testing.
