.............Made the trek from So. Cal to Winnemucca, NV for the 3rd annual rodent elimination outing :-) We only managed to shoot for 2 days this year, but both days were perfection and you'd have been tempting fate to even THINK about how the weather could have been nicer. Air temp was about low-mid 70's but the sun was sharp and bright. We were also blessed with little to no wind until the second day, when it would bluster on occassion.

In attendance was BruceB, Ammohead, NVcurmudgeon, myself and Ron a friend of mine from Prescott, AZ. Also 2 co-workers of BruceB's, Dusty and Dave. When Ron and I checked into the motel in Winnemucca, while carrying in our stuff to the room I realized I'd left my range bag with all my ammo at home! BruceB to the rescue as he supplied me with 300 rounds of 223, that was so close to what my rifle was sighted for it made no never mind. As I'd also brought my CZ 22RF bolt gun Ron supplied me with all the Dynapoints I could shoot.

Left: My ho-made collapsable sniper tower and Savage M112, 223. Right: Ron is low between the Sport Trac and Ammohead's white Dodge, with Ammohead up on top. Then Dave shooting from a bench in the back of his pickup and Dusty standing in the bed of his truck shooting over the cab. That's BruceB in the red shirt shooting from the top of his Suburban. I failed to get a shot of NVcurmudgeon, and he was shooting from a bench on the ground on the other side of BruceB's rig.

Left: A shot from the varmint tower. The Savage is a single shot but several times I had to stop as the barrel got HOT! Right: Southbound on US 395 south of Bishop, CA. Those are the Sierra Nevada's on the right, and we're a bit south of Mt Whitney. We hit some rain and hail off and on from Mina, NV and then really ran into it as we left 395 and picked up I-15 south.

Since I was shooting ammo provided by BruceB I strived to take only the shots that I figured I could for sure connect with, and managed to cut his supply by 300 rounds. Between Ron and I with the 22's we managed to shoot away a bit over 600 rounds. I sure wished the CZ had had more then a 5 round magazine, as Ron had three 10 round mags for his 10/22 and was really doing some de-population work.

We'd parked right in the middle of a huge concentration of the pests. The shooting was steady until about noon when they'd hit their burrows for a nooner, which just a few up and active. About an hour, hour and a half later they'd be back up again with reinforcements. As I'd left my range bag at home that meant my Ruger MkII 678 wasn't available and that was too bad as there were squirrels no more then 10 feet away from my perch. By the afternoon of the 2nd day the ground and burrow mounds out to a couple hundred yards was simply littered with the remains of the departed.

The last shot was taken by Ammohead the afternoon of the last day. We'd all packed up and were standing between my truck and Ammohead's Dodge drinking beer and summing up the day's events. A squirrel probably puzzeled by the lack of shooting happened to stick his head up out of his hole, not 6 feet away. Ammohead reached into his Dodge and pulled out a S&W M25. I can surely attest to the fact that a 45 cal SWC at 6 feet will for sure put out the lights of Mr Ground Squirrel :-)

Sounds like a fun trip to the happy hunting grounds.

Looks like "bringing your own tree" is the only way to go in that area. Were there other folks hammering the little "ground pounders" in the area (ref: top photo of Ron - vehicles lined up off to the right)?

And lastly, does your ho-made "tree stand" rotate around or is it fixed? Looks like a really nice design. I've got alot of extruded aluminum, thanks to the local scrap recycling yard & about really to start on a portable stand, but haven't really gotten to the cutting stage yet.

buckshot,
What load are you using on the 223?
What boolit?
Am getting ready to load some for my H&R Handi and was wondering.
Would like the info to put in my load manual

Nice shooting guys. FYI, CZ makes a 10 rd magazine for the 452, it's plastic vs steel but functions fine.

Since Buckshot was shooting my ammunition, having left his at home (!), I will answer this question.

I must point out that I have three .223 rifles, an AR-15, a Mini-14, and an Interarms Mark X Mauser. From my point of view, it is undesirable to have separate loads for each rifle, and therefore ANY of my .223/5.56 ammunition will work in any of the rifles.

Also, although I mark loads in military brass as "5.56mm" and in commercial brass as ".223", there is NO meaningful difference in weight (and hence capacity) between military and commercial cases. Therefore I load all of them with the same load. This does NOT APPLY to the 7.62 NATO and military .30-06 brass, when they are compared to the commercial counterpart. In these calibers, military brass is thicker and heavier.

The powder I use is H335, at a charge weight of 25.0 grains with 55-grain bullets. I've used this charge with Hornady 55 full-metal jackets, Hornady 55 softpoints, and Hornady 55 V-Max bullets. From the 20" AR-15, velocity is very consistent at 3100 fps, and accuracy is very good from all three rifles. Primers are CCI400, and over-all length is 2.324" which works well in all the rifles.

I must warn everyone against the use of "FC"-marked (Federal) military brass. A considerable number of my FC cases have had partial head separations, neck splits, and body cracks, a sufficiently-large number that today I junked every single FC case I could find on hand. This amounts to almost a thousand cases, none of which had been reloaded more than twice after their first firing. NONE of the other headstamps I have here suffered any casualties at all with the same loads and service history. Don't use this brass!

I shoot Highpower Rifle Matchs and its common knowledge around those circles not to use Federal 223 cases because you'll be replacing the cases twice as fast as other cases.

Thanks for the load data Bruce!
Also thanks for the heads up on the brass

............Yes it does rotate. Due to it's having 3 legs the seat will swing through a 120* arc. However the arm supporting the benchtop will swing, and in addition the benchtop will also swivel so you can actually swing your crosshairs through almost 180*.

Most Important to me was to make it sturdy, and reduceable to easy to handle pieces so it was easily transportable. Since I'm not a materials engineer, nor do I have a degree in Civil Engineering I defaulted to the Soviet practice. This is to use heavy durable pieces :-) LEFT: This is the central base that everything is built upon (I'd just made it in the photo). RIGHT: Here it is with the 3 legs in the pockets and the central post in place. This photo shows the 'Pinch Clamp' which hadn't been added yet in the first photo.

http://www.fototime.com/01F7B3DC72BD359/standard.jpghttp://www.fototime.com/2682667A3314523/standard.jpg

LEFT: This is a rather poor photo of the other pinch clamp, of which there are 2. The first is atop the central base. You slide the central post into the base, and then tighten the pinch clamp. This clamps it tightly in place. The one in the above left photo clamps the central pivit post into the central post. RIGHT: This is the upper end of the central pivit post. The central pivit post has a 4"x 4"x 3/8" piece of steel welded on as a bearing plate. Through the center of the plate is a 2" hole. A length of 2" OD steel black gas goes down through the hole in the plate and into the square steel tube of the pivit post.

The seat swivel is merely a piece of reciever hitch tube and a plate welded top and bottom with 2" holes that goes down over the 2" pipe and sits on the bearing plate that's welded to the pivit post. The benchtop swivel is the same only being shorter. It also goes over the 2" pipe and sits on top of the seat swivel.

The Pinch Clamps are 1-1/2" wide pieces of hitch reciver tube. They have a cut made through the wall at one corner to give it room to move closed. A 1/4" thick steel tab with a 1/2" hole is welded on one side of the slot. A 1/2" bolt is then welded on with it's threads spanning the slot and going through the hole in the tab. A Pinch Clamp was then welded to the top of the Central Base. The 2nd Pinch Clamp was welded to the top of the Central Post. Only 2 sides of the Pinch Clamp were welded. The wall with the tab and the adjointing wall. This way when the nut is tightened the bolt pulls the 2 opposing sides closed. The 3 put together pieces (Base, Central Post, and Pivit post) are then rock solid with zero wiggle, yet when the nut is loosened they easily slide apart.

LEFT: Boring the 2" hole in the bearing plate. Naturally you could use a 2" holesaw but I didn't have one. RIGHT: Milling the 4 flats on the 2" OD steel pipe. Since the pivit post is 2"x 2"x 1/8" OD square steel tube, it's 1-3/4"x 1-3/4" ID so I had to mill 4 flats on the pipe to get it to fit into the square tube. There are other ways this could have been done. However this was another one of my projects started with an idea, but no DRAWN PLANS!

Very nice explanation & photos - thanks a bunch. That looks like it would be rock steady. I doubt if I could find 10 square yards of ground on my or my dad's property that was flat enough to sit it on, but that looks perfect for your application.

Several great ideas you've used there.
