Fooled around with some alternative powders for the 9.3x62 and thought I would share my results.
These loads were safe in my rifles but might be excessive in yours.

Ruger #! - 22" barrel:
250 NAB - 60.0 - AR-Comp - 2675 - 1.1" group
250 NAB - 62.5 - Varget - 2655 fps - 1.1"
250 NAB - 62.5 - N140 - 2640 fps - .84"
250 TTSX - 60.0 - N540 - 2543 fps - 1.1" This is the only promising TTSX load so far
286 NP - 60.0 - AR-Comp - 2432 fps - 1.1"
286 NP - 60.0 - N140 - 2435 fps - 1.1"
286 NP - 66.0 - Big Game - 2486 fps - 1.1"

Titan 16 - 22" barrel:
250 TTSX - 60.0 - N140 - 2598 fps - 1.4"
286 Hdy - 56.5 - N140 - 2400 fps - .9"
286 Hdy - 58.0 - N540 - 2425 fps - 1"
286 Hdy - 59.0 - N540 - 2486 fps - .7"
286 Hdy - 59.0 - N150 - 2474 fps - 1.5"

The Titan 16 (a clone of the Mauser M96 Straight Pull) is made by Roessler in Austria. It is finely made and accurate. The bolt has more internal parts than a Bavarian cuckoo clock. The owners manual (when I finally obtained one) states that the bolt should never be disassembled. The importer seldom gets anything from the manufacturer and, as yet, has not come up with a spare magazine. I like the rifle. But had I known the ultra-complex bolt could not be taken down for maintenance I would have passed it by.

Cheers,
Walt
