Hi, I'm wondering if there are any TCU sooters that have tried Rel. 7. I have a 257 Raptor from Gary Reeder witch is based on the 222 mag. case. I've used H4895 and IMR3031 with great success but I can't get the velocity that I should before the case is too full. I have alot of Rel.7 that doesn't fill the case so much. I don't have the chance to do alot of shooting with out driving 30 miles to the State forest where I can use my crony so I'm just trying to save some driving. I figure if it works well in the TCU's it should work good in the raptor. Thanks for any input.
