Congratz on the Buck yorke! And thanks for the info. 
I have a question, what is a 6.5 LBC? And another question, I am getting pretty serious about a centerfire rifle for my daughter. She is small. I am familiar with the usual "small" deer cartridges, 7mm08, .243 etc..... but these other calibers sound like they may even more shootable for small frame shooters and/or able to be built on platforms that may be more comfortable. Is this true or not? Sorry to derail, if i need to start another thread I am happy to!
The 264 LBC is just a 6.5 Grendel with some changes to the throat angle. It shoots factory 6.5 Grendel just fine. The 6.5 Grendel, if you're not familiar with it, is essentially a 7.62x39 case necked down to 6.5 and improved slightly. Kind of like a 6.5 PPC.
I had the little CZ 527 used on these 2 deer built for my son and it's perfect for him. It started as a 527 Carbine in 7.62x39 and I had it rebarreled by Grizz Precision to 264 LBC/6.5 Grendel with a 20" barrel. The size and weight is perfect for small stature shooters, but not so small that it won't fit a full size adult, even a guy who's well over 6'! I like it so much that it's become my go to truck/walking through the woods rifle. I believe that Howa has a new mini action that they're chambering in 6.5 Grendel as well which would likely be a faster, less expensive way to get the same result.
There are quite a few new cartridges floating around that were originally intended for the AR 15 platform that (like the Grendel) that would work great in a little bolt action too. I'm a big fan of the little 6mm BR case and the other rounds built off of it. I'm just starting to work with another round called the 270 AR that should offer a decent performance advantage over the 6.5 grendel. It would be a great round to chamber in one of these little mini actions if you could make it fit.
