I concur with Roskoe, go with TSXs instead. I used to shoot the 130s in my Warbird a spot or two faster than the Ultra and they simply will NOT fail. I even purposefully double shouldered a large buck once at 45yds just to test the bullet (had already tested it on about a dozen bucks and does at longer ranges) and the buck went down like it was struck by the hammer of Thor and surprisingly there was no bruising too the meat. But the bone fragments were found at each end of the animal (drove them through the neck and also into the hindquarters). Either bullet just goes in and goes right out the other side. I have NEVER lost an animal with either of the loads (50 and counting) and the destruction isn't nearly as bad as my other mags with softer bullets. They penetrate like solids. In fact I have taken several "texas heartshots" at over 300yds and all that happened was the deer had two rearend holes, a new hole in their necks and they went straight too the ground like you hooked em up too a 220V.

The only downside too the old Xbullet are their accuracy. That is the reason the TSXs were created. I switched too the 150TSXs when they came out a few years ago and now won't switch too anything else. The 130Xs would only do 1.5" @ 100yds from my Sako. The 150TSXs do .5" @ 100yds, 3.5" @ 400ydsand are less than 200fps slower than the old 130s. The grooves in the TSXs not only reduce fouling but reduce pressure and increase velocity all other things being equal. I would try the new 130TSXs if they were loaded by Lazzeroni for my 'bird just because. But I have used the 150s with so much success (whitetails, muleys & antelope) that I can't imagine what a 150 doing 3800fps wouldn't do that a 130 doing 4k fps does.

Good luck,
RA

ps
Fouling wise, I know the old Xs DO foul barrels. The loads I always shot were/are NP3 plated so the fouling isn't a problem, but I shoot other TSXs (non-plated) in some of my other guns and they foul less than anyother copper jacketed bullet I have ever shot. I simply think they are THE perfect bullet. The new polytipped Barnes' I am sure are GREAT bullets but I think they are more for marketing and because folks just THINK they MUST have a polytip bullet. The regular nose on a TSX is damage resistant and very aerodynamic to begin with. I am not worried about changing.
