I had one of these rifles built by a well known PA gunsmith, really nice handy package. It didn't take any special skills to load 180 grain Nosler partitions to 3000 FPS (24") and I usually got them to shoot 3/4" five shot groups if I had a good "trigger day." Off I was to BC and Alberta for an elk then a muley hunt.
On the elk hunt the 180 grain Nosler Partition @ 3000 FPS did what you would expect it to do (2002 before Accubonds were proven in my mind) on an elk. But on the muley hunt I had a feeding issue on a needed follow up shot that caused me great effort to finally anchor that buck. The feed rails were also very sharp as I requested. So, that was the end of that caliber in that rifle.
The question was what could I do with a McMillan action built for the Patriot in a rifle I really liked? The answer was we chambered it for John's .338 Galaxy short mag with a 24" #2 Lilja; what a cool round! 2950 fps or so with the old 200 grain ballistic tips and a shade over 2600 fps with 250 grain partitions. Nosler is now showing 200 grain 338 Accubonds so that is what I will load up next. This rifle shoots easy 1/2" groups with the ballistic tips and I have a couple of 1" groups at 300 yards. It is a tad over 7 lbs with a Swarovski 3x12x50.
Sheep/moose hunting in the Yukon sure made me comfortable with a 338 in my hands in grizzly country. I took 210 partitions for that hunt. I have tried 100s of times to cycle that bolt in a way to cause the Galaxy cartridges to jam like the smaller diameter Patriot case did and it never has...
Very neat cartridge and now that John has quality brass hulls for loading, this equal to the venerable 338 Win Mag in a short magnum is a lot of fun just like the Patriot it originally was first.
My friend regularly shoots at the 1000 yd competitions at the Tucson Rifle Club west of Tucson. There is a guy there that shoots the Patriot for both light and heavy rifle matches (same rifle) and is very competitive winning many of the prizes. IIRC he is using the 210 VLD. Sorry can't tell you any more details about his rifle.
