The 300gr XTP Mags were all over the place and had to be seated using a block of wood and hammer!!!
That is not right... did you purchase a pack of them? Probably Hornady... If you did they came with the HPH-12 which is to thick.
Your new barrel is still really tight after you shootit a bit it will also loosen a bit. Cayugad has a JB bore paste treatment that will really help smooth and polish that new barrel get him to explain the procedure.
In the meantime you may want to get some MMP HPH-3p-EZ load sabots from MMP or some Harvester 'crush rib' sabots to shoot those XTP's in they will shoot very well from you gun.
A better choice, in my mind, would be to buy a box of Spreer Gold Dots.. these bullets are bonded and are really tough. My choice for deer would be the .452/250 grain Gold Dot. You can find these in the reloading section and then get a pack of either MMP HPH-24's or a pack of TC Sabots... they both should should be black sabots in color. If these are to tight you will need to move down to the thinner 3p's or crush ribs.
Shock Waves are way to expensive to be shooting paper with.
Good luck - but your gun will dial in great with time...
