168 ttsx Seating Depth

Ok,

Im fairly new to this reloading thing, and am getting an order of stuff ready to try in my 300wm.

I already have lots of 200gr accubond. 165gr SST.

I was looking at the 165gr TTSX, but I read on website that the like to be seated just off lands:

"Barnes recommends initially seating bullets 0.050" off the lands. Best accuracy will be found from 0.030" to 0.070" depending on the rifle."

It will be shooting out of my a-bolt, and must have a COAL of 3.35 (maybe +.006) to fit the clip.

The lands are @3.5"

So I am wondering, is it worth trying, can I get them to shoot decently with the "jump"?

I dont want a single shot rifle outta this.

Just wondering from your experiences

Maybe i missed something but why cant you go shorter than 3.35? Unless i missed something i would think that you could easily achieve the .05 jump recommended.

Re: 168 ttsx Seating Depth

From my experience the Barnes TTSX bullets like the jump, so you should not have difficulty in finding an accurate load. I have been able to find accurate loads for a number of rifles shooting the TTSX bullets, including 30-06 's, 300 WSM's, 280 Rem, 260 Rem, and 243 Win..

I can go shorter than 3.35" that is what my clip will allow. But my lands are out to 3.5" so.......

Maybe im missing something, but wouldn't I need an OAL of about aprox 3.45" to make the .050 jump? Cause that aint fitting in my clip.....

Like I said maybe Im missing something in this concept.

Re: 168 ttsx Seating Depth

Your title line states the 168 ttsx and you asked about the 165 ttsx ? Either one has some things to consider according to the Barnes #4 book for the 300wm. They state for the 165 powder charges of less than 100% should be used and for the 168 seated to saami max of 3.340 the case mouth falls in front of the bullet olgive and they recommend crimping to improve feeding. Hope this helps.

Ok cool, tks every one for your posts, I will have to go home tonight and re measure my lands.

What method do you guys use to do this?

I talked to a couple reloaders, and they told me they took a empty cartridge with bullet barely seated and seated it in the chamber, measured it and that gave them measurement to the lands. They said it would be the easiest way for me to measure it.

This is what I did to measure mine, but like I mentioned before, I am new to this and wanna do it right.
