Home Forums Hunting & Shooting Ask The Gunwriters Getting TSX's to shoot

In both directions.

Every one of my rifles has responded to the "Kiss lands, find pressure, rock on" way of doing things when shooting TSX's and TTSX's.

jstall,

Contrary to popular belief, primer flatness often has nothing to do with excess pressure. I can explain why if you want, but it's true.

The Ramshot rifle powders tend to shoot their best at maximum pressures, usually at least 58,000 psi and sometimes more. A lot of handloaders get confused by this, when starting loads don't shoot all that well.

I'd start with the bullet seated a little closer to the lands, .03 or even .02, as I've often found them to shoot very well seated close, despite the Barnes suggestion. Keep adding powder until the velocity is up where it should be, at least 3000 fps or a little more.

If the rifle doesn't shoot well at that point, seat bullets deeper, about .03" for each sample.

If that doesn't work, I'd have to ask if you've checking bullet runout on each round.

There's a reason I click on all of JB's posts!

Good info.

More heads spinning and flying into orbit.

I would start off with a .050 jump, then work up a load. The go to .040 then .060...expect night and day differences.

All tripple shocks in 243, 270, and 7mm I have worked with have shot exceptionally well. I am not convienced that they are a better bullet to hunt deer with vs cup and core bullets and bonded bullets. Partitions are the benchmark in my book.

I have a good bait of .224 caliber Speer 64g Bonded Gold Dots I want to try this fall.

Thanks for the info Mule Deer. I shouldn't have much runout, as I use a Redding Competition seater. So I shouldn't worry about the primers to much and add some more powder. I'm about 3 grs. off of max. (47 grs.) I will try this and see how it works. I would really like to use these bullets if I can get them to shoot.

I use them in a ruger #1 in 7x57 (160gr), and CZ550 in 9.3x62 (250gr). the #1 will shoot them to close to MOA until the barrel heats up but the 9.3 will shoot clover leafs all day long. the 9.3 is seated .02 off and the 7x57 is just slightly more at .025.

Seat depth and a clean bore are critical in loading the TSX for accuracy. I wouldn't mix shooting NBT or other bullets while you are working on getting your tsx's to shoot. If you haven't already, clean out all the copper using a strong solvent like CR10, sweets 7.62 or similar.
Once that is done, I start at .055" off the lands. I have found my best accuracy loading these from .055 to .060 off the lands, loaded up to near max powder.
Seat depth is the most critical factor once you find your max powder charge. In my 7 RM I was getting groups right at MOA, I adjusted the seat depth .05" in and cut group size in half.

He's tried everything that Ruger just don't like em period! I on the other hand have had absolutely no problems with 53gr TSX'in my swift,85's in my 243 and 6mm,130's in the 264,140's in the 280 and now TTSX 150BT's in the 300 Win.As others have mentioned my best performance has been with them seated deep off the lands and yes running them on top end seems to help..

7mm-08 - 120gr TTSX, out of a Kimber Montana:



OAL 2.75" , 50 gr of Big Game. Work up, that's close to max. I have not chrono'd them as it was raining hard that day, but they grouped well. The barrel doesn't look so hot in the borescope, but it shoots well with TTSX, and Nosler Partitions. Count me as someone who's had good luck backing TTSX's off .050.

Now that said, I was shooting 53 TSX's in my #1 .22-250, and because the brass was new, I purposely ran the bullets touching the lands. The goal was to keep the case head against the breechblock in firing. With a mild charge of Varget it did about an inch at 100 yards, which was better than I expected.

A few more comments, since several people have added to this thread:

The reason to start with the bullet seated as close to the lands as possible is that backing the bullet off results in lower pressures. If you start with the bullet backed off, then seat it closer to the lands after working up a "max" load, pressures rise, sometimes a little too much.

I've never noticed much difference in accuracy when shooting TSX's in a barrel that's already been fouled with other bullets. I shoot 'em all the time in previously fouled bores, most often when shooting a bunch of different handloads using a variety ofbullets for an article. Things were different with the older X's, because they fouled so badly, but I haven't found TSX's to copper-foul any more than conventional bullets, and they often foul less.

Yessir! Never a bad idea to start touching the lands, and work back from there.

I've also found TSX/TTSX bullets to foul very little.

Where do you find such bullets? Don't see anything like that on Speer's website. thx

All bullets always shoot best kissing the lands at max pressure.........

I used to think this also, but I'm not sure "ALL" applies to the Barnes bullets.

What've ya got to lose by trying a kiss?

May work great, did for me.

Oh I'll try it, especially since the loads are several grs. from max.

Nothing to lose*, may work great, has for me too.

But "always"? Snork


*gotta be extry-careful working towards max in lands contact though IMHO.
