N555 for 6XC with 115 DTAC

[9146gt]

Any thoughts on using N555 for 6XC with Dtac 115 and where to start.

38.2 H4350 and a 115 DTAC gets me 2888 FPS with a 30" 1X7.5 Kreiger.

Thanks
Tom

Thanks for the update.

30" barrel spitting 115's should have no problems getting 3,000 fps with some of the double base powders.

On the other hand,.. 2,800 fps will extend the barrel life
