Thread: Reducing ES - 223

So I have been fighting my Bergara 223 to get it true moa - 10 shots in 29.03 at 100M.

The load I've been using is 23.5 of 2206H behind Hornardy 73gn Eldmsvwith Fed 205s, it's shot nice 3 shot groups but isn't doing the business at 10.

I've tried several things and today's effort centred on brass. I had some fresh Sako brass, once fired from factory in the Bergara.

So l neck sized it (Lee collet die) and loaded as per above .

It shot the smallest 10 shot groups yet (1.13 MOA), but with an ES (70 plus fps, SD of 28) well above what I've been seeing.

Thoughts?
