Everyone should have a 223 bolt gun. Or at least a barrel for your match rifle. I started with a 24" medium palma and went 26" heavy palma on the next barrel. I don't try to get fancy with it by using custom throats, 88's, or Lapua brass. It would take the fun out of it for me. Because at that point why not just load and shoot the 6BR. I have a "universal" load using 75's, LC brass, AR mag length. This load shoots lights out at 2950 in my bolt gun and also killer groups at 2800 in my 20" SPR'ish gas gun. Both Wylde chambers.
The fun in it for me is mass loading really accurate ammo and always having a can of it on hand. I started with about 3K pieces of once fired LC brass and spent a weekend running them through a Dillon RT 1500, frame mounted swager and M die expander. The brass pops out resized, headspaced, trimmed, swaged, 2 thou neck tension and the inside burs from trimming knocked down. I wet tumble after to remove the lube and it knocks down the outside burs on the neck. I haven't second-time loaded any of the brass yet, although I'm getting close. I've only handled the brass once. In a mass manner, never single handedly with each piece. Started out with 3 jugs of 8208 and two 4,500ct bulk packs of Hornady BTHPs. Cheap, easy to tune and accurate. Better BC than the 77 SMK. I would put this load up against Black Hills match. It shoots better and faster than MK 262 out of my guns. And temp stable on top of that. And it's the easiest thing I reload.
I also had a 20" 22BR on my Tikka. I struggled to get 88's past 2950. I eventually just went with a 22" 22Creed. I don't plan on using it's full capacity. Just want 88's on cruise control at 3200. More or less a hunting rifle barrel in CF for my T3.
