9.3x62 tsx/gmx loads
- Thread starter turbo250
- Start date
you can start from there:
h t t p s ://load-data.nosler.com/load-data/93x62-mauser/
and here:
h t t p ://www.hodgdonreloading.com/data/rifle and you can see the limit is 58.0 grains for both powder for tsx less for nosler ...
but remembers the gmx is creating more pressure than the accubond or even the tsx ....
i do have somewhere the hornady data ...

I thought I had some 9.3X62 TSX load data, but it appears I don't. The good news is that since Barnes banded their X bullet and re-branded them with the TSX moniker, there isn't the significant differences in pressure with a given load that was safe with a lead core bullet of equal weight, that could occur with the old plain, solid shank, X bullets. When I was developing a load for the 250 gr Accubond, following Whynot's recommendation, I used fire-formed .30/06 brass, first neck expanded to .40" then resized to .366" to create a false shoulder for headspace. I determined the maximum load was 60 grs of H-335 for a velocity of 2635 according to my Oehler 35P; when I observed extractor marks on the case heads. My working load for this bullet was slightly reduced to 59.5 grs for an average 2624 fps for 5 rounds, with no pressure signs evident. If I was working up a load for the 250 gr TSX, I would begin at 55 grs and proceed with 1 grain increments until pressure signs were observed, being sensitive to the fact that an equal weight lead core bullet gave pressure warnings at 60 grs. Now you might run into pressure signs at 59 or even 58 grs, or you might not until 61 or 62 grs, as much depends on the volume and hardness of brass you use, and the internal dimensions of your rifle, which will almost certainly differ from my rifle. I chose H-335 for no other reason than it was a powder I had on hand that was within the correct burning rate, not because it gave the best accuracy or the highest velocity.
The Hodgdon reloading page suggests a starting load of 52 grs of Varget, and a maximum of 58 grs. Due to some of the variables I refer to above, starting at 52 grs is probably prudent, then work up loads in 1 gr increments up to say 60 grs, using a permanent market to write the load on each cartridge, to prevent confusion at the range. Should you determine your maximum load is less than 60 grs, as soon as possible, pull the bullets of the cartridges with greater charges. If you get up to 60 grs without pressure signs, check the velocity against the book velocity, and if it coincides or is slightly greater than the velocity for the book maximum load, that's nature's way of telling you to stop there. If you are getting pressure signs on your brass, its prudent to drop a half a grain, and fire 5 rounds to see if the pressure signs persist. If no longer evident, that is your working load, otherwise back off another half grain, and shoot another 5 rounds. It is possible that you have soft brass that gives false pressure signs, but don't assume that is the case, load up a different batch brass, and see if the pressure signs persist.
Much is made of the accuracy of one load over another, and yes accurate ammo makes us feel good, but in hunting ammo we are primarily concerned with reliable cycling and terminal performance. For that reason I full length size all my hunting brass and to hell with case life, and drive the bullets as fast as is prudently safe. The primer pockets usually fail before the case cracks appear anyway. In the field, where the opportunity to shoot from prone is rare, its unlikely that you will be able to shoot up to the accuracy potential of your rifle-ammo combination anyway.
