I want to try loading some leadfree ammo - might as well, the leadban is coming here too.
But these bullets are expensive so I'd like to hear from people who have already tried these bullets in a 1-12 twist.
Which one shoots better in your gun? I'll use them for foxes - and maybe on very rare occasions, a roe deer.

Here's something to ponder...

Hi.

My hand loaded non-lead .223 ammo is the Barnes all-copper 62-grain and it is acceptably accurate and has very good terminal performance. I push it with Varget and a CCI #41 primer.

I think if you have a 1:12" my first attempt would be the 50-grain.

Good luck! Let us know.
