I broke down and ordered some 115gr. TSX's for my 257R. Anyone have any suggested loads? Are these like the GS Custom where you are supposed to drive them faster than normal jacketed bullets?
Thanks, peter.

I'd like to know how these work. I've been thinking of buying some and loading them for my 25 WSSM.

Use H-4831 and work up. It will probably fill the case, and then some, before you get pressure signs. You might try a drop tube. The actual amount of powder will be more than the books suggest. They keep the pressure extremely low. H-4831 will likely give the highest velocity of any powder.

I also used to use H-4831 with 100 gr bullets. I just dipped the case full of powder and seated a bullet. velocity was over 3200, pressure signs OK, accuracy good. Almost too simple.

We used the 100 gr. TSX in all of our "Quarter Bore" rifles(.250 Savage, .257 Roberts, .25 WSSM, .25-06 and .257 Weatherby) this last deer(and on Wild Boar) season with great results. They will penetrate as well or better than 115 gr. Nosler Partitions. Excellent accuracy and flat shooting. Haven't yet tried the 115 gr. TSX but will do so soon. The TSX has made a believer out of me. Lawdog

Thanks gentlemen. I am more interested in accuracy at this point, thats the real reason I decided to try the TSX. My Ruger Ultralight is, unfortunately, not very accurate. I believe I have some H4831 at home, so will give it a try.
Peter.

If all you care about is accuracy, why are you using these expensive bullets? 115 grain ballistic tips and the CT's are pretty tough to beat, and are cheaper than TSX bullets.

Mrhawg, I have been using various target bullets (SMKs) plus Nosler Partitions in 100 and 120 gr. varieties. Not much luck. I had heard good things about the accuracy of the TSXs, so I thought I would try them. heven't tried the BT's yet. Aren't the CTs the same as partitions just with a moly type coating? I use the CT in my 300WM, 180gr.They have a black coating. I have a Ruger Ultralight which may be part of the problem. What loads are you using with the BTs?
Peter.

I have the same rifle, Ruger Ultra Light .257, and it is also a fussy rifle. It gives good accuracy with the factory Winchester loads. For handloads, the Sierra 117 grain Pro Hunter with 43 gr. RL-19 has been the best for 117 gr. bullets. It doesn't like max loads. 39 gr. of RL-15 with most any 100 gr. flat base bullet is also a good load. I put a piece of credit card between the fore end tip and barrel to put some pressure on the barrel and that also seemed to help. I love the rifle for hunting and have taken several deer with it but it is mediocre at best on paper. Merg

What seating depth are you guys seating the TSX?

The TSX bullets seam to like alot of velocity.
They are extreamly accurate in my Ruger#1 at 3420 ft that is with Moly plated bullets and Reloader 22.

The 257 Roberts likes H4350 and IMR 4350 in a moderate load. I calculated that the 100 gr TSX
bullet needs 3200 ft to have 125% stability.
But found that in the Roberts with a 1-10" twist
This bullet shoots well at 3050ft.

In the 25-06 I load .010" into the lands while I do better with .005 off the lands in the Roberts. My 257 Roberts is very finicky about pressure, being an H&R break open rifle with its
wiggly lock up that is understandable which in some instances will open when the rifle is fired.

No they are not. Allthough i heard that the tsx are very accurate.
The gs customs or the KJG bullets are the only bullets with real driving bands which make them faster than other bullets without exessive pressure. Yesterday i read an article where a hunter shot an roe in germany at 423 Meters with the 180grain GS HV-bullet out of his 8x68S...
