[QUOTE="surgeon260, post: 1432949, member: 103874"] I have both. First of all, my experience with 260 has been very different than Schnyd112. Keep in mind that in the world of custom barrels and chambers, there can be a lot of variation in throat length. I have a 27" 260 and I shoot 140 Berger Hybrids in a short action out of an AICS magazine (which limits you to a COAL of 2.88"). Using H4350 or RL17 I can easily push the 140s above 2850 with great brass life and no pressure signs. I have been over 2900, also with great brass life (RL17 only), but accuracy was best in the mid 2800s. I also have room to spare in the case, so the observation that the bullet is going to displace tons of powder simply isn't valid with a slightly faster powder. 4831 is slightly too slow of a powder for the 140 class bullets. Switch to something a little faster (H4350 is the gold standard) and the 260 will shine. Comparing a x47 using Varget to a 260 using 4831 is apples to oranges. Now, as to whether to get a x47 over a 260: almost every variable is going to be a wash. Both have outstanding Lapua brass, and the ballistics with most projectiles will be indistinguishable. Some might argue that the small rifle primer in the x47 offers minor precision and brass life benefits, but that has not been my experience. 260 brass lasts forever and the rifle is crazy precise. The x47 has a couple small advantages. The first is if you want to run the really heavy new bullets like the Sierra 150 MK or the forthcoming Berger 155 EOL in a short action. If you are limited to 2.88" COAL with those super long bullets, then the shorter case of the x47 means you can seat the bullet out further and displace less powder while still fitting in the magazine. However, I would argue that neither the 260 nor x47 are ideal for those projectiles from a case capacity standpoint. The second advantage the x47 has is that due to the shorter case and longer neck, it is better suited to seat bullets so that the bearing surface is above the donut. Not a show stopper, but important to some if you shoot the same brass a lot. I solved the problem in my 260 brass by reaming it with a K&M mandrel. You only have to ream it once, typically after 4-5 loadings. The 260 has a couple small advantages. One, more case capacity means you more velocity potential. I can push the 130 Berger ~100fps faster out of the 260 when running both to the max. Two, you can form 260 brass from 243 and 308, which are everywhere and cheap. If I were to buy only one 6.5 for PRS, I would get the x47 so that I could remove the donut removal step. But that is really splitting hairs. 260 is an awesome chambering too. [/QUOTE]
