Need Load information for 150 barnes ttsx in 7 STW

[ODAVID]

I am interested in any suggestions for loading the 150 ttsx in 7 STW.
1)Can you share with me your starting load ranges and accuracy load range for different powders?
2.) Any suggestions for seating depth?
3)Any further helpful experience???

Thanks ODAVID

I shoot 150gr TTSX in a Blaser R93. OAL is limited by the mag. 81.0 gr of H1000 gives me .5 to .75 MOA at 3250 fps. Nosler brass and Fed215M primers. Hope this helps.This is less than max loads per Barnes Manual but is accurate and exceeds their vel for that load.

I contacted Barnes and they sent me the load data for the 150 TTSX
Most accurate load (I found this to be true for my rifle too) according to Barnes:
IMR 4350 68.5-73.0 gr which should top out around 3187 fps
73.0gr was my most accurate load without any pressure issues (0.546" moa), I actually got 0.30 moa with 74.0 gr but sticky bolt and flattened primers, so I backed off
Best COAL was 0.05" off my lands
All were Nosler brass and CCI 250 primers
Hope that helps
