I just read an article in rifle shooter about the new triple shock bullet from barnes. have any of you folks used it yet or is it even available yet? it sounds almost too good to be true. I am sure that the Barnes bullet will perform well but my biggest concerns are accuracy and barrel fouling. I would really like to hear of real life testing. I plan on trying some out in my 7stw when i get the opportunity. here is a link to the article if anyone is interested http://www.rifleshootermag.com/ammunition/triple_0723/

They are available and have been for quite a while. As a matter of fact they are already changing them from a triple rib to a quad rib. Supposedly they get a little more speed and possibly even less fouling. I have some of the older triple shocks loaded but haven't shot them. Almost everyone who has shot these has been VERY satisfied with the accuracy. On game performance will be normal barnes--that I can report from experience has been excellent.

I am having excellent success with the .308 180 gr TSX in my 300WSM. Consistent 1/2 MOA groups, and very consistent velocities with 65.0 Grains of IMR4350, Fed 210 primers and Win. cases with an OAL of 2.860 which is .040 off the lands in my chamber. I am now shooting the 4 ring version and the load produces about 65 fps more velocity with the same charge as the 3 ring bullet did. I took 2 whitetails this fall, both dropped in their tracks at about 80 yards. One was a neck shot just below the head and had obviously expanded from the exit. The other was a slightly quartering towards chest shot that left an exit like someone had drilled a hole into the deer with a 1" wood bit.

I have gone through Rifle Shooter's article on the triple shocks and I find one inconsistency in Brooks' reasoning when he explains that cutting grooves into the bullet shank actually improve accuracy.

He says, "Grooves provide kind of a relief valve as the bullet metal flows under pressure while traveling down the bore. Instead of copper being dragged from the front of the bullet toward the base, this material expands into the grooves. This, in turn, changes the harmonics in the barrel and produces tighter groups."

Looking at the picture of an unfired bullet beside other three at different stages of expansion it may be seen that the last groove is very much forward in the shanck, which means that there will still be a relevant amount of copper dragged from the bullet shanck with no groove to be deposited or, using Brooks own words, with no relief valve for it.

I've used Xs for years with some success, but the triple shocks are impressive. My 270 and '06 shoot very well and important to me, clean easy, especially the match barrel. On mulies the 270 130 gr at 100 yds straight on destroyed his internals and came to rest in a rear ham, at 424 yds entering just in front of the shoulder exiting with a 2 1/2" hole at the base of his neck. The one I recovered was a text book Barnes mushroom with four jagged petals a little over 1/2" across!

I've had good results with the 168 gr. Triple Shock in my .300 Weatherby Sako. I've been very impressed with its accuracy and its performance on whitetail deer. It's a very good bullet in my opinion and one that I will continue using for sure.

I had great luck with the 180gr 3 rib design with 88gr of RL25 in my 300RUM. I got three 5 shot groups less than an inch at 200 yards. Then all the sudden, they changed the design to the 4 rib. Tried them on Sat, same load and two different COL. Also tried upping another grain to 89gr. But couldn't duplicate the groups. Still got 1.3" groups at 100yards, but that is a far cry of less than an inch at 200 yards. Now the other difference is I ran out of RL25 and bought another new pound. I guess I will play around more with the COL. One thing I can say is these newer 4 rib design doesn't foul as much as a 180gr partition or even a matchking. It amazing the little copper fouling I had.
