October, 2015

 

The Colorado High Country will test the boundaries of heart and soul of any hunter, and the outer limits of rifle ballistics too. I hunted mountain goats there in September of 2015, and if their was ever a caliber made for such a task it is the .30-378 Weatherby Magnum.

Originally designed for the military in 1959 by Roy Weatherby, it was not available to the general public as a factory offering until 1996. I suspect that the majority of big game hunters have still never heard of it, even though it was used to set world records for accuracy at 1,000 yards and held that record for decades. It remains the fastest .30 caliber ammunition on the market.

I have a friend that is a big fan of this cartridge, and he is an old hand at long-range precision rifle shooting. He once took an elk at 750 yards, and when he heard that I had drawn a goat tag he all but insisted that I give it a try. He said that this was probably the closest it would ever get to a mountain goat, and he wanted a picture of the two together.

Now that’s a buddy and a pal that you can count on. There are not a lot of people in this world that would hand over a $2000 rifle with a finely engineered scope and a $150 box of shells and encourage you to go play in the rocks.

The thought of attempting a shot over several football fields stacked end to end is one that I would not generally consider very seriously, but then again I had never shot a rifle quite like this. After all, that’s exactly what this rifle was built for, and reason enough to own one.

I had my opportunities too. On this trip I had to pass on some really big billies, but not because they were at 500 yards or more. Shot placement is always important, but in goat hunting it is what happens after the shot that is of paramount importance.

Each time the goat was in a spot which would have made recovery impossible without ropes and climbing gear, and my head said no while my trigger finger desperately wanted to say yes. More than one trophy goat has stumbled and fallen a long, long way down the mountain after failing to be anchored by what appeared to be a great hit.

It took several days to find one in a reachable spot. As it turned out, there was no need to worry. I shot my Billy with a 130 grain handload at 350 yards, and their was never any question about the end result. It simply never knew what hit it, and was down and out on impact. The round got there in one hell of a hurry too.

The .30-378 Weatherby Magnum is truly a high performance hunting caliber. You may wish to take one along on your next mountain hunting adventure.

I know I will.

Update:

As it turns out, it does appear that I was able to take a very solid mountain goat for this unit. According to the Colorado Big Game Harvest Statistics for 2015, my goat was about 5 years old and had horns that were a bit better than average compared to other goats taken that year.

That’s some fine news, to be sure. Yet, I must tell you that in the end the length of the horns don’t really matter, at least to me. The real prize was the mountainous adventure of it all, and it’s a fantastic trophy no matter the score.

May you draw your own tag soon!

“Roy Weatherby has left an indelible mark on the gun industry. His story began in earnest following his first deer hunt in 1942, which resulted in a wounded buck that left him both frustrated and convinced he could find a more effective way to take an animal.

From that day, Roy embarked on changing the way the world viewed ballistic performance, championing the use of lighter weight bullets at ultra high velocities with maximum energy…the foundation for what would later become known as the Weatherby Magnum.” – The Weatherby Foundation

    1. Well, you have me on that one! That was my intention from the beginning, but the woolly buggers would not cooperate. The closest I could ever get was 340 yards. Needed some stronger medicine…
