1263 Yard Rockchuck

My nephew took a rockchuck at 1264 yards yesterday.

Here's the pic. (Red arrow shows the location of the rockchuck.)

And, now the story.

It's getting close to the time our rockchucks will be going down for the year so I wanted to make a hunt this week. My son, Ben, is out of town visiting his brother so I asked my nephew, Gus, if he wanted to go along. He was game so we headed out to try to get to a promising looking canyon I'd seen while Ben and I were hunting last week. The road was horrible but we eventually made it to within a short hike of the canyon.

We set up on one rim of the canyon and began glassing. Eventually I spotted a couple of rockchucks beyond the far rim of the canyon standing up in the grass. They offered good shots but poor spotting. Gus ranged the area with his Leica 1200 at around 1250 yards. He only had ten rounds of ammo for his .308 with him. He told me that the previous two rounds had scored on two sage rats and one bear and he wanted to keep his string going. I suggested that if that was the case, he probably wouldn't want to start shooting at 1200 yard rockchucks. Being the sensible young man that he is, he decided he might as well take a poke at them anyway.

Gus had not shot the particular load he was using past 500 yards and the longest kill he'd made with the gun previously was around 550 yards on a prairie dog on our Wyoming trip two summers ago. With no drop chart we just discussed things and took a guess based on my drops. I told him to dial in 48 minutes of angle elevation and five MOA of wind. I told him I hoped I could see his shot in the field of view of my spotting scope which didn't instill a lot of confidence in him concerning our dope.

Shooting location.

Gus shoots a Remington 700 SPS in a B&C stock (I think) with a Leupold Mark 4 4.5-14X scope. It definitely wasn't too much magnification for the situation! He told me later that the horizontal crosshair was covering the whole 'chuck. He dialed up, settled behind the rifle and squeezed off the shot. I was actually able to call the shot. It was within about one minute on windage and several feet low. I told him to take one minute of wind out and come up another six MOA. That got us in the ball park on the next shot and he ended up with 58 1/4 minutes of elevation in the scope and three minutes of wind.

The shots from that point on were all very close. He was close enough that he was scaring the rockchucks off with each shot and we'd have to wait to find another in a position where I could spot the shot before he could loose another round. Long story short, on round number seven I saw no dust and the rockchuck took off like a scalded cat across the rocks and onto an angled face of a ledge where it launched itself into the air off a 40 foot cliff! We could see it wasn't running correctly but didn't know whether Gus had just hit it in the leg or what. He felt good enough about it to want to go check. I on the other hand wasn't nearly as excited.

One challenge of long range shooting is the retrieval. This 'chuck was a long ways away and across the canyon and, because of the rimrock, I didn't know how far we'd have to go just to get to the bottom of the canyon which happened to have a good sized stream running through it. But, being the good uncle I am, I went along. It took us over a half mile and one very large rattle snake to get to a spot we could descend into the canyon. When we got to the stream, the run-off made it more like a small river and that was where the whole Good Uncle thing gave out.

Gus stripped down to his skivvies and carried his pants and shoes across the swollen creek. I didn't know if he was going to be able to stay upright in the current but he's shaped like Gumby so he doesn't displace lot of water. He made it out, got dressed and headed up the other side of the canyon. I watched through the spotting scope as he climbed up to the bottom of the bluff and a minute or so later he was holding up his 1264 yard rockchuck! Turned out to be a centermass hit with close to a one inch exit. I think the rockchuck was dead before he hit the ground.

Gus refording the creek with his trophy.

It took nearly three hours to get to the 'chuck and make it back to our shooting location where we finished the "photo shoot".

Gus is really looking forward to rubbing his new record in his cousin's face. Ben had pretty well stopped reaching out past about 1100 yards thinking his family record was safe. I can already envision Ben's drive to move beyond 1264 yards. He's got his work cut out for him but somehow I think he's up to the task!

I never fired a shot but it was good day with a good kid and and one exceptional shot.

Re: 1263 Yard Rockchuck

I really like reading stories of young shooters doing some awsome shooting. Granted, I'm only 35 but it is neat that there are young people getting into hunting and shooting.

tt35 I have a few questions. Are what you call rockchucks the same as what we call groundhogs or what other people call them woodchucks? I live in Ohio so that is why I'm asking. Other question, you say the rockchucks will be going down soon, is that for hibernation? Our groundhogs will still be out until it gets cold.

Keep up the good posts.

Re: 1263 Yard Rockchuck

Thanks a lot! It was a pretty incredible shot!

Cornchuck: Yeah, rockchucks are the western equivalent of your woodchucks. They are somewhat different in their habits. Our rockchucks will start to go down in July. I think it coincides with the cheatgrass turning brown. If I remember from my high school biology correctly, its called a summer quiescence. I understand that they may come back up in the Fall for a short period before winter hibernation.

ICANHITHIMMAN: Gus was shooting a 175 gr SMK from his .308. He said it was leaving the muzzle at around 2700 but I'm not sure if he actually chronographed it or not. WW cases, Fed 210 primer and I think he's shooting IMR4895 but I'm not positive. His data is in my reloading room but I haven't looked at it.
