I recently went with a Credo HX 2.5-15x42 that will be mounted on my rifle for muley and elk hunting. Just waiting on rings. Trijicon scopes are very nice scopes.
Barnes has some load data for those bullets. I would think H322 would be too fast of a burn rate. I would try IMR 4895 first.

I worked up a load with 3031 in 223 and 55gr Ballistic Tips. It shoots sub moa for me with good velocity. It is a compressed load. 3031 fills a 223 case very quickly.
I sort all rifle brass by headstamp. There can be enough difference in case capacity between brands to make a difference in pressure. My pistol brass is sorted but thats because it was basically sorted when I started reloading the way I had it stored. I have heard a lot of guys dont bother...
I carry a G20 with night sights. I like the size of the G20 better than both the 40 and 29. If you're looking for something optic ready you could also look at the new M&P 10mm. It can be had in a 4" or 4.6" barrel.
You're going to have to go above book max loads to get there. AA#9, Longshot and Blue Dot all being good powders for full power 10mm loads. Start low and work up slow with a chrono. What bullet are you going to use?
I use Boretech as well. I have Eliminator, C4 carbon remover and Cu+2 copper remover. All of them work great. I really like the C4 for cleaning anywhere carbon builds up like my AR bolts.
