[QUOTE="Shootin4fun, post: 971976, member: 28741"] With that kind of speed, you'll need to keep your shots to longer distances or else loose significant meat to bloodshot. Maybe this next part should be in the reloading forum: I have shot a fair amount of TSX and they have performed very well out of my 270win. Some bloodshot will occur even at 2600fps but expansion is controlled and penetration...well do I really need to say it? Now I'm trying TTSX because they're supposed to open up at a lower velocity, allowing for slightly longer shots (+ a better BC). Anyway, the 130gr TTSX is .100" longer (!) than the TSX and the ogive is a little different. I am using a bullet comparator to measure ogive and I also measure COAL. Now, if I load the TTSX at the same ogive length so that the jump is basically the same, then it is about .040" deeper in the case and still .020" longer COAL. My question is, does this require a lower powder charge in order to avoid excessive pressure problems because the case capacity is being decreased? Will I get the same velocity with a slightly lower charge because of that? [/QUOTE]
