The Barrier bullet just had a thicker jacket as to go through glass and car doors, not a Interlock. Try that jug test with a 100gr Hornady HP in a 7 Stw just under 3900fps.

Or a Speer 125gr TNT HP out of you're 300Wby around 3750fps.

Guarantee a more violent episode

A while back we were discussing these bullets made for Hornady .223 TAP ammo that have been discontinued and were being dumped very inexpensively. (Probably gone now.) Somebody asked me how they performed, and I could only comment that they were accurate out of my Savage 12BVSS .22-250. Well, yesterday I performed a very brief and unscientific terminal performance test. I carried a gallon milk jug full of water out to the range, and after everybody else went home I put it in the grass in front of the benches so it was lying horizontally on one corner, and fired into it so the bullet passed diagonally through the body of the jug to get the longest possible path through water. It hit perfectly, as could be told by the entry hole. The load I used averages 3256 FPS at about the same distance as I shot it. The jug flattened completely, the split running from the entry hole up to the top corner, and the flat bottom (facing away from me) burst. The water sprayed in a mist for the most part, about as violent an explosion as any I've produced with any load. I looked for the bullet or fragments, and found none. There was no exit hole, the water pressure having opened the plastic ahead of the bullet. The bullet apparently exited as an intact mushroom. I found a shallow groove in the damp soil about as wide as my little fingertip and about 6" long that the exiting bullet had made before it glanced upward. I suspect that if one wants to use a .22 centerfire for medium sized game, this would be a good bullet for the job. It won't be as explosive on small varmints as some, but I expect it will do the job. As previously mentioned, it's just a pointed soft point with the jacket running all the way to the nose and a small meplat with no lead protruding significantly beyond the jacket. Just a slightly elevated "meniscus" of lead. Dunno if it has an Interlock ring inside the jacket, but I wouldn't be surprised if it does. The standard Hornady TAP ammo for .223 has plastic tipped bullets that look like V-Maxes and are supposed to have limited penetration. I haven't been able to find any info on TAP "Barrier" loads, but presumably they were supposed to hold together better if they had to penetrate some intervening barrier before hitting the target.

Well, I'm certainly not going to shoot a deer with this. I know that some people do use .22s for that sort of thing, though. They'd be a lot better off with one of these than with the typical 55 grain soft point, I think. But like I said, this is only one brief, unscientific "test." I'm certainly not advocating .22s for "big game," and that was only a passing comment in my note.

John, You may be perfectly correct in what you are saying. Before anyone desides to shoot any game even the size of key deer I think you should have A LOT MORE real objective evidence. Unfortunately I have had a lot of experiece using a 22-250 on game it should not have been used on. Even with bullets supposedly designed for deer the results were not always consistant.The gun writers of that era had me believeing in the supremacy of HYDRAULIC SHOCK. That's a joke boy!!

Now I have used this bullet last week at the range and got some decent results in my Varminter.

Yeah, I've done it with a 110 gr. .30 SP at about 3200 FPS, and it did a good job on the jug. Haven't tried loading up any top-velocity varmint loads with the .300, but I'm sure they'd be plenty explosive.
