  • OT: Groundhog season revisited

    On Friday, I was asked by a couple of members about the gun in the following post.

    I like to build and tinker with rifles. The rifle I used for that (850 yd. rockchuck) shot was a big .22, i.e. a 6.5 x 55 Swede case necked down to .224. It has a 30" straight cylinder barrel (1.25" diameter from breech to muzzle). It is built on a trued Remington 700 action with a 2 oz. trigger, and the whole barrel and action are attached to a McMillan Tooley MBR stock via a barrel block in front of the action. This means the action and barrel are free floated with only the barrel block touching the stock. At the moment, it's wearing a Pentax 8.5 - 32 X scope with a mil-dot ranging reticle, mounted on tapered bases. The tapered bases are so there will be enough elevation adjustment in the scope to get out to 1,000 yards and beyond. It is set up with a tight neck chamber (you have to turn some brass off the case necks to get them to fit in the chamber) and throated to use custom 80 grain bullets made by JLK. These come out the end at close to 3600 fps. The whole thing weighs almost 20 lbs, so it is shot off a bench/bags -- not offhand. Lot of $ and time in it, and it's only good for shooting chucks. Not to mention the rangefinding gear, etc............

    This is a photo per the request. Hope I'm not too far out of line.

    VERY nice
    I like the ace of spades on the stock too
    How far out was that shot?

      850 yards. 1200 yards has been done (maybe more), but I haven't had that opportunity. A lot of things come into play at these distances, i.e. wind, mirage, etc. Every error gets magnified at distance. While these animals can get pretty large (I'd say maybe 25 lbs. in some cases), your target is probably on the order of the size of a football. This is really off topic, so if anyone wants it to go away, just say so.

        Can't be off topic, machine work was required.
        Nice job, interesting caliber.

          I have an ignorant question: How would the original 6.5 x 55 Swede cartridge perform at that distance when handloaded with proper bullets?

            Very nice work Lynn. I wished I could get that kind of velocity out of my AR's! Have you played with the 90gr. bullets yet? Who's barrel are you using and how many rounds are you getting out of it?

            Al, The best 6.5mm bullet for that distance is the 142gr. It's a VLD design, Very Low Drag. The problem with that bullet and the 6.5x55 is lack of case capacity to drive that heavy of a bullet. The Swede can push a 107gr. at respectable velocities but the 107 will not shoot inside a 142 in the wind.

            This is line of thinking where the 6.5x284 came from. I get 2950fps out of the 142's with mine. I have gotten over 3000fps but accuracy suffered.

              That's a fine gun. I LIKE!!

                I've tried JLK 90's in it, but they are on the ragged edge of stability in the 8 twist Krieger barrel. I'll get groups of 4 in and 1 about 1/2" out. I've got less than 400 rounds through this one, so I don't really know, but I suspect this caliber is somewhere in the middle of the barrel burner pack.

                    MY old 220 swift, I don't remember the bullets weighing that much for sure. I would shoot golf balls out of the neighbors pasture at 2-300 yards. It swooshed out over 4,000 fps. But a lighter bullet would not carry like that. Flat trajectory up to 500 yards. I remember 42 grain bullets, but my memory is crap these days.

                    I shot watermelons at 500 yards with the M1A, never hit every one, but about 1-2 out of 5. Lots of chances to miss at that range. Just a heartbeat out of time I think. I love the 308. Research shows most long range target matches are won with that caliber. High energy round , brass filled with powder gives a uniform ignition. Plus they are common as fords or chevys. My handloads ran about 2700 fps (165gr bthp), not smokin, but reliable.

                    Have you looked at the accelerator rounds instead of necking down a cartridge? I wonder about the long range accurracy of them.

                    Fun messing with Straight people with a custom cut brass, A 44 automag can shoot from cut down 308 brass. Let someone pick up your brass and read the headstamp and watch thier eyes. (cut them down with a tubing cutter and trim to size) You shooting 308 rounds in that pistol?

                    I never saw a prarie dog that large, but then I thought the blacktail deer in Colorado were elk at first. And them jack-ass rabbits with the top of the ears at hood level to the car.

                      So is it more of a pink mist, or a water balloon going off when you hit the woodchuck with that?


                      • #12
                        BillH -- More like a water balloon. Turns the surrounding rocks all red, green, and brown with a good hit.

                        IBEW -- These aren't prarie dogs. They are chucks (wood or rock, depending on location in the country), also referred to as ground hogs. I believe the proper name is Hoary Marmot, and they are a lot bigger than the prarie dogs.

                        One advantage of shooting long distance is they don't associate the distant boom with the little buzz that went by before they heard the boom. They often keep on going about their business until the end. They devour tons of alfalfa and hay because their diet is green stuff, so the farmers and ranchers are tickled to get rid of them.

                          Groundhogs.. Okay. I shot arrows at one locally here that weighed in at 45 lbs. I thought it was a bear cub when I first saw it. (seriously niave back then) I had to climb down and get my arrows several times that day, never did hit the rascal. When it ran a fat roll on its back made it look larger than it was. A friend later killed it with a rifle during deer season. He ate it.

                          Ha.. Good memories of hunting, enjoying the outdoors, the weather and a good sport.

                          We have removed predators of small animals by incroachment upon thier habitat. Someone, or something must control the smaller creatures and thier numbers. Otherwise they become a major nusiance. (really all animals)

                          BillH: the watermelons would spray, a noticeable hit.. Really a lot of fun. I have shot clay skeet? targets that explode too, lots of fun and you know when you hit for sure. Not like a tin can where you shoot in front of it to make it move. (playing kick the can w./rifles)

                          All target shooting should be encouraged in our Youth. America needs riflemen akin to Seargent York. I have gave away several nice 22 target rifles to aspiring young people. China (norinco) made a nice bolt rifle you could get for $75 at one time. BUT, that was when I had a very positive cash flow.

                            Dads been playing with a Ruger 22-250 heavy barrel for better than 20 years now (yikes, back to that feeling old thing again) I remember him buying that rifle. He was a happy camper. That thing will ring a g-hogs bell something fierce. We will sit in a soy bean patch out in the country and let'em know we are watching them. I have a 22 hornet that g-paw brought back from WWII. It was sitting in a gun shop booby trapped. Small string on the strap went to a shotgun that was sitting behind a cupboard. Grab the 22 and boom. Luckily, he was smart enough to know better. Let the demo team clear the shop before taking it for a long "test drive". I get them in the short stretch and dad smacks them when they are out a bit past me. What fun and the farmer will pay for the bullet when we bring in the hide. Come on summer!

                              When I was stationed at Mtn Home AFB in Idaho, we'd go out and shoot what was locally called 'whistle pigs'. I've never been able to determine if they're the same as pararie dogs. Can anyone shed light on that question?
                              Those little fellows were pretty small, maybe 7-8" or so tall,at the max, when standing erect. Mostly they'd be found in the onesy-twosy's, but sometimes you'd find pretty big villages of them (i.e. hundreds).
