16B,
How fast can you push those 108's in a 260?
We know a 105 can get close to 3000 fps from a 243 for comparison. The HPBT has a .530 G1; the Hybrid is 0.547. A 105 Hybrid at 3000 fps seems like a lot for little if you can bear a Burger

Don't know about the 108, but the 6.5/123 Skinner has the BC to match the 6mm/105 Hyb (both around .540)... and most 22"+ barreled .260's will clock 2900-3000 with 123s. Em's CTR is running them at 2850 in a 20" barrel with only 39 grains of 4064... that's pretty efficient.
Dope for my 23" .260 running 123 Amax was almost identical in both drop and drift with dope from the 24" .243 running 105 Amax. But, there's a definitely a difference on impact... the 6.5 123 hits noticeably harder and flings goo further.
I can see how PRS type guys gravitate toward the 6mm's... as it's simply about making hits, and a lot of them, over the course of a day or two. They don't have to knock anything down... or chase a plate for miles after a close "miss". Steel ain't tough to kill...
