Barnes Manual

I noticed some of their revised data is softer, I wonder if they had a lawyer looking over their shoulder or if he edited the thing himself.

Example

264 WM

130 gr. TSX FB

3rd edition RL-22 max 61gr. 3134 fps

2008 data (march) RL-22 max 58gr. 3057 fps

3rd edition was X bullet, not TSX, and the data is not transferable as both give different pressures.

And the information that came in the box with my tsx bullets indicates that for the tsx,you can use the data for the original x,and if no pressure signs are evident,you can increase the powder charge up to two grains.That makes the new data appear to be much milder.
 
So the data for a 200 X bullet from the No. 3 Manual might not be quite right fot a TSX? It would have to close, eh?

Do I need to buy the No. 4 Manual? Is there enough new info to warrant it?

They also mention to start at minimum charges and work up, which in that theory, you could use data from any book for the TSX...

FWIW, I couldn't even get close to the max X bullet data with a 225 TSX, let alone go higher...

Stiff bolt and shiny ejector marks...

I took another look and that's 100% true about X and TSX - I read a little too quickly :redface:.

Either way I was shooting the TSX and used the 3rd edition data. I worked up carefully to 62 gr. with no pressure issues, I might work up to 63 on the next trip. Depending on how that goes I may switch to US869 to get more velocity

62 gr. = 3187fps (24" barrel)

Should get 3229 fps or so with 77gr. of US869

Which is exactly what I do.I use Nosler or Hodgdons starting loads and work up.I am finding that my tsx loads have on average 2gr to 3gr less powder than my Nosler loads,but the velocities are slightly higher.I don't even own a Barnes manual.
