Re: 3/8" and 1/2" steel gongs

I'll ask for it next time I'm looking for free remnants at the steel yard. This guy wanted to give me a 3.5'x4' sheet of 3/8" mild steel last time I was in, wouldn't you know it, I had no way of getting it home.

It would be nice to shoot a little offhand out to 500 or 600yds on the plates, just don't feel like making up new ones every week because there full of holes, if you know what I mean.

Re: 3/8" and 1/2" steel gongs

I went shooting the 308win at the gongs on saturday. I made it to 700yds with a new load.

Groups were slightly over 1moa all the way out. 9" at 700 in about a 25 to 30 mph headwind that was at about 11 o'clock.

It took about ten rounds to get on the gong at 600yds, couldn't tell if it was windage or elevation.

I was only following a round about chart for my other load so I wasn't sure.
I finally made a hit, 1.5' right on the other gong. Well, one adjustment and I was in the center.

After 10rds on each of the three gongs I repainted them and went to 700yds. This time it only took 3 or 4 rounds to get on the steel.

The wind had died off a bit so I held the same as I had at 600yd. It was off just enough to completely miss a couple times. I figured my elevation was close enough so I held over a little more each time. Bingo, bottom ctr.

I decided to wait for a calm day to go out to 800 and 900yds. After that I think the bullets will loose stability judging by the speed they're starting out at.

Well I got the chart figured out for a good practice round anyway, at least out to 700.

Too much fun!!

Re: 3/8" and 1/2" steel gongs

Brent,
Have you tried getting a partner to set up a spotting scope directly over or along the rifle's line of fire, so that he can try to spot the bullet in flight. Seeing the swirl or trace as it is variously called is a great way to get onto the steel as you go farther downrange. Seems late in the day is particularly good for seeing the bullet's trajectory up here were we shoot.
Are you using the .308 wind chart that calls for one less MOA than the first digit of the distance - for 10mph full value winds.

Happy steel clanging!

Re: 3/8" and 1/2" steel gongs

I'll have to try a spotter next time Ian.

The wind chart was for full value five and ten mph and the wind then was very hard to pin down, it was shoot to see only then. I need a wind meter bad.

The LRF helped me learn range, to a point, now the wind is killing me so a Kestrel I figure will help here.

I was watching a Kestrel 4000 on Ebay at $100.00 but I went back to bid later today and WOW it was over $200, it sold for $220!

By the way Ian, my dad has a "Toy" truck too, I'll send you a picture of it some time.
Everbody loves a Toy.

Re: 3/8" and 1/2" steel gongs

Talk about shooting steel...I found a commercial steel target webpage that has some great targets. Pricing is a little high end (for me), but the webpage has lots of good info, a good "hardness of steel" page, and lots of good ideas to copy for the "do it yourselfers". I can get 1/2" thick, 12" square, T-1 for about $25 locally that can keep me busy while I save up for one of their "pneumatic reactionary programmable pop up target systems.

Lemme know what you think.

Re: 3/8" and 1/2" steel gongs

Brent,
We shot steel Fri and Sat and learned a few neat things. We had some odd-ball pieces of 1/2" mild steel cut in 6"x6" squares with 1 1/2" stubs welded on them, sort of looked like a T. There was a 1/2" hole drilled through each stub which was good for hanging the little plates.
Shot one at 700 and only took the paint off.
Next day we shot them at 300, hanging them from an old swing-set from pieces of chain. 168 Sierra's and Nosler J-4's penetrated about 1/2 way through the plate, slight bulge on back but one weld failed and the other welds holding the stubs started to crack. Very visible fan of bullet debris hit straight under the plate each shot (lots of dust), no richochets, seems all bullet material bounces downward. Had about a 20' embankment directly behind the steel so no worry about stopping bullets.
Moved in to 200 yards, broke off two more stubs and had noticeably bigger and deeper craters. Moved in to 100 yards and craters were about 3/4 way through the plate, big bulge and the plates started to bow, not flat anymore. All of this was hitting them when they were hanging. Pretty well buggered the plates we had out but my buddy has 20 more.

Bottom line - 6" hanging plates at 300 are very good close-range practice, particularly if you shoot from various hunting positions. Welding was not a good idea, next plates will be one piece and simply have a hole drilled in each corner. We had them on two feet of chain, made for some good practice hitting them as they swung after a previous hit.

Also shot 2'x4' 1/4" plate at 700 yards, .308 makes a pretty good dent. .300 Win went through with 190 M'Kings. Expect that the .308 will make it through when an impact location is hit twice. What the hell, it is only 1/4" steel, easy and cheap to replace so we will just shoot them up. Is still a great way to get your LR zeros as we just repaint and the fresh hits show up well.

Shot a heavier 30"x30" piece of .375 plate and it took the hits no sweat at 700, makes a much nicer gonging sound too. Had it sloped forward one day and the bullet damage was nil - deflected all the debris into the dirt.

Also shot rocks, they are almost as good if you spraypaint them white - you can see your bullet splats really well. We have a big valley mapped now, distances and come-ups to several good rocks plotted (it helps to be crazy...). 168's were carrying up flatter than 175's yesterday at the extreme distances.
Longest shot on a rock yesterday was 75 minutes of elevation plus held the post about 12-13 mils over, using a tree up on the horizon of a huge valley, had on 20 minutes of right wind also. Rock was in the bottom of the valley at far side and the 168 J4 hit it, nice puff of dust. It was not in the field of view of the 16 power Nikon tactical at the shot. I was spotting and watched it hit, about two sec. of flight time. Total fluke but fun. Must be sort of similar to what the extreme range hunters do on a regular basis, only we had to hold-over since we ran out of UP.

Not as much fun as Dave's dep deer but still good trigger pulling.
