I have some of these to load in my rifles but I find little to no info on reloading them. Can you use the available Barnes 250gr. TSX info even though the Swifts do not have the pressure grooves in them? Any on game experiences with them and reloading info much appreciated....thanks in advance....bearit...

I'm a fan of ramshot big game in the 9.3x62. Here's the info i got from ramshot.
Caliber: 9.3x62 Mauser
Barrel length: 24�
Powder: Ramshot - BIG GAME (1st Choice)
Bullet weight: 232 grains.
Start load: 60.0grains (2400 � 2500 ft/p/sec)
Maximum load: 65.0grains (2650 � 2750 Ft/p/sec).
Bullet weight: 250 grains.
Start load: 58.0grains (2300 � 2400 ft/p/sec)
Maximum load: 63.5grains (2550 � 2650 Ft/p/sec).
Bullet weight: 275/285grains.
Start load: 56.0grains (2250�2350 ft/p/sec)
Maximum load: 62.0grains (2450 � 2550 Ft/p/sec).
Bullet weight: 290/300grains.
Start load: 54.0grains (2200 - 2300 ft/p/sec)
Maximum load: 59.0 grains (2400-2500ft/p/sec).
I never could get the 250gr A-frame to group well. The 250gr TSX ended up being the most accurate of the 250gr bullets in my rifle.

Tim M....Thanks for the load info....I have 2 9.3x62's a Tikka and a Sako and I've been doing quite a bit of reloading for them...I've got the 286gr. Hornady shooting well and with speed,the 250gr. Nosler BT doing very well[took my first black bear with it in nov.]....but the first thing I notice is that the cannelure on the 250gr Swift is pretty far back on the shank of the bullet....it puts the bearing surface way further toward the lands as say the BT....could be good could be bad. I think that the Barnes 250gr. TTSX is almost too long for it's own good as it is the only bullet I've worked with that will limit powder space....even in a Tikka...the COAL in the Sako+Tikka is fairly well unlimited but that Barnes is long...I bought the Swift 250's to see if I can get the same integrity with speed. Boy...if anybody has some history with the Swift I would appreciate it....thanks again....bearit....

Use a Lee factory crimp die and forget about the cannelure on the 250gr Swift.

Not a writer nor have I loaded for the 9.3s but have encountered high pressures when trying to extrapolate TSX data for much stickier bullets like the A-Frame.
Had to break down a bunch of .375 loads when I used the Barnes data for Swift and Alaskan bullets. A heavy but under max load for the TSX produced sticky bolt lift with the other two. This was with R15. Worked fine in cold weather but not safe in hotter temps.

I'm wondering if it is lack of pressure grooves carved into the shank of the bullet....another reason I'm being a little cautious....bearit....RL 15 is on the list....

The re-leaf or pressure grooves make a big difference. The bearing surface and alloy are a factor too. Longer bearing surface higher pressures. Higher or pure copper alloys can increase pressures but hard to generalize about this as it is a friction factor and how much obturation or bullet upset that takes place. Probably several other factors in there I am not aware of.
Bottom line is extrapolation is a fools errand, I do know about this from lots of experience, as an errand boy.
