Hi All,
There seems to be some people out there on the web looking for reloading data for this powder. So I took it upon myself to email Alliant, and it turns out that they actually HAVE done some testing with it in this caliber. I assume the data would also work for .375 Ruger, albeit, slightly lower pressure and velocity for the same bullet and powder weight. I started 10% under these charges and stopped short of them. There really is no need in the .375 to push it to it's max, but as you can see, the numbers are pretty good. Here it is, straight from the horses mouth:
Christopher,
Below is the load data that I have for the 375 H&H cartridge using Alliant Reloder 17 propellant:
Powder Bullet Brand Weight OAL Primer Brass Status Charge wt (gr) Velocity (ft/sec)
Reloder 17 Nosler 260gr Accubond3.580 215 Fed 81.5 2711
Reloder 17 Hornady 270gr JSP 3.580 215 Fed 85.0 2826
Reloder 17 Hornady 300gr JSP 3.580 215 Fed 81.8 2685
Reloder 17 Nosler 300gr Partition 3.560 215 Fed 83.0 2687
Hope this is of assistance.
Thanks,
Shoot Straight

I loaded up some 270 grain blems from Midway as well as 270 grain interlocks and 300 grain SGKs and my Chronograph showed astoundingly high velocity for the charges I put in. The Sierra Game King with 75.0 Grains of RL17 put out almost 2600fps so I stopped there even though the primers were barely flattened and there were no signs of pressure at all. I don't need a 300 grainer going faster than that. I pushed the 270, starting at 72 grains all the up to 80. The last few loads had substantially more recoil and when I chronographed them they were running about 2780fps from a winchester Model 70 with a 24" barrel.
Just thought I would pass this along for those interested in this powder. The groups I shot measured on average, about 1-1/4" - 1-1/2" at 100 yards. That is plenty good for anything I plan to hunting with it. I use strictly Alliant powders because they are mostly available where I live, they are great, and $3 or $4 cheaper per pound than Hodgdon and significantly cheaper than Vihtavuori powder. Hope someone finds this helpful!
