Lee why not try the new 250 TTSX?

Work up with RL15 til you hit 2850 or so and see how that shoots.I've been shooting 250 gr bullets in the 375 for quite awhile with good accuracy,to 400 yards or so.I use BBC's but I think the TTSX will work really well at that velocity.



The 280 Remington is overbore.

The 7 Rem Mag is over bore.
