Boar Sight Shooting School

Cooper Backcountry lightweight rifle in .300 winchester magnum


Preparing for my upcoming CA Desert Bighorn Sheep I bought a Cooper Backcountry lightweight rifle in .300 winchester magnum. My beautiful custom classic in .270 shot so well I was confident they could make a light weight and accurate rifle. The rifle is 5 3/4 pounds! Should serve me well on any sheep hunts. I topped it with my go to Leupold 4.5-14×40 scope with the compensation drop (CDS) turret system. The hunt requires using non-lead bullets so I bought Hornady Superformance GMX and Barnes TTSX. The fast Hornady rounds are slated at 3260 so was hopeful they would shoot well. My first chance to sight it in at Los Altos and while they looked promising they just did not cooperate. I cleaned it well saturday night and returned Sunday to try the Barnes loads. My first group was an inch. Second group one ragged hole. My six 3 shot groups averaged 7/8″ so happy it is shooting them well!

Next step is attending Kyler Hamann’s ‘Boar Sight Shooting School‘ Kyler was the guide on my first hunt ever in 2002 when I took a great trophy wild boar. He has an incredible set up with hanging 8″ steel plates at distances out to 600 yards to replicate ethical shots on game. He even has a 30″ plate at 1000. I brought all five of my rifles dialed in and hoping to see them shine at distances I might reasonably take shots at game. For the Sheep hunt the goal is to be able to shoot 400 yards. The guides at Dry Creek say most shots are around 200 but want to be ready. I did not have time to have a turret made for the Backcountry so I had to fish one out of my bag that looked close. My 30.06 for Hornady 150 SST looked close all out to 400 where it drops about an inch more. So meet Kyler at the gate and follow him to the bench and start off with the Cooper. Just resting it on bags it rings the 300 plate no problem. After a couple shots on it the plate is hung up. He also has a board next to it for a group. I shoot a group at 300 as he watches through the spotting scope. It’s about 1.5″ at 300 yards. So time to try the 400. I hit the 400. Ask him to video and see if I can do it again. So happy to hear the distant ting and know I just put a round into 8″ vital zone of a Desert Bighorn. (volume up to hear the hit)



This is a great day and I shoot all five of my rifles. The two the really did well are my Remington custom rifle. This rifle was the original bargain basement ADL I took that pig with in 2002 with a Simmons 8 point scope and factory trigger. Since completely customized. It had no problem hitting the 400 and even the 500 yard plate. I didn’t try the Backcountry at 500 knowing that turret would be off. My other Cooper with the beautiful presentation grade stock has been sitting in my safe for seven years. It also hit the 500 yard plate! I’m a Cooper believer.

After finishing shooting all my rifles we decided to try to hit the 1000 yard plate with my Remington. My dial only goes to 600 and we could not even get it to the point we could correct from. Kyler asked me if I wanted to try his Cooper XLR Long Range rifle. Also in .300 win mag. Sure why not. He has it topped with a great NightForce scope. My first shot is near target and Kyler makes corrections on the dial. I have a clear image and my second shot is a hit. And my third shot hits again! Incredible to be making accurate shots at 1000 yards. That is a long way. Kyler tells me I hit it, and near center, all before I even hear the sound. I finish up by putting a bipod on the Backcountry to prep for hunting pigs at sunset. It should be fine at hunting distances. I lay down and hit the 225 plate, the 250 plate, and then the 225 again. Call myself ready. Well we saw a couple small pigs but not the boar I was hoping for. My freezers are full of elk and deer so we called it a night!

I have a Cooper Jackson Excaliber rifle on the way in .300 Weatherby. I’ll be bringing that to the range when it’s all sighted in with turret. I will definitely come back again one more time before the Cady Mountains sheep hunt which starts right after Christmas.
