Thanks, I will be caution, after what happened to the guy from Sarco.COTW, 7th edition gives:
Several shooters have complained that loads in that book were on the hot side, so be cautious.
From Sharpe's book:
65 gr. lead - 4.0 - Unique - .250" seating depth
95 gr. lead - 5.0 - Unique - .250" S/D
112 gr. SP - 10.0 - Unique - .229" S/D - 1380 fps - 22.5K PSI
112 gr. SP - 14.1 - Unique - .229 " S/D - 1730 fps - 37.0K PSI (At or near maximum)
112 gr. SP - 12.0 - 2400 - .229" S/D - 1400 fps - 20.5K PSI
112 gr. SP - 19.5 - 2400 - .229 S/D - 2020 fps - 37.0K PSI (At or near maximum)
112 gr SP - 27.0 - IMR4064 - .250" S/D - 2200 fps
112 gr SP - 32.5 - IMR4064 - .250" S/D - 2540 fps
Sharpe was unimpressed with the 112-gr. bullet in this cartridge. I believe it might have been too long for the very fast twist in this rifle. For other reduced loads, you may want to consider using .243 WCF or .244 (6mm) Remington data as a starting point and reducing them slightly. Per the Manual of Cartridge Conversions: Case volume of 6 mm Lee Navy: 3.25 cc's, .243 WCF: 3.42 cc's, 6mm Remington: 3.53 cc's.
Ackley's book had the same data as Sharpe.
Good luck and post your results.
IMR powders changed formula at some point in the postwar era, c. 1960s if memory serves. I wouldn't use Sharpe's data at least for IMR powders as it predates WW2, and I would want more up-to-date data on the chance the other powders have changed.
