So Remington optimized the rifles for 120 grain bullets...which kinda defeated the whole purpose of the cartridge.

With standard short action magazines you would need to seat the base of a heavy bullet DEEP into the case, reducing powder capacity. The Creedmoor solves this by using a shorter case leaving more room in a short action magazine for the bullet, and then raising the max pressure to allow the same performance as the 260 Remmy in a shorter case. The 6.5 Lapua takes it one step farther by shortening the case even more and using an even higher max pressure (blown primers are common in the Lapua).

In a single shot rifle you have no such limitations. I know of LR target shooters that love the 260 Remmy, but then they have single shot target rifles.

I had a single shot falling block chambered for it at one time, but the barrel was too light leading to rapid heat buildup in the barrel. Again, not the fault of the cartridge itself.

Thanks much! What about "6.5 Creedmoor?" I understand it's a direct competitor to .338 Lapua Magnum. But I'm also finding a bunch of LR Rifles available and "in stock" for 6.5 Creedmoor... not necessarily the same weapon in .308 Win, which is what I'd like to get.
