Hi guys I've recently re-barrelled my 300 win mag in a 1:12 twist 30" and I can't seem to get hornady 180 sst's or nosler 180 ballistic tips to shoot even close to Moa. I was starting to worry that my new barrel was no good till I shot through some 125gr nosler ballistic tips which shot under 1/2 Moa consistantly. Now I like the 180's for long range hunting but I'm thinking that 180's aren't stabilising?? The guy who sold me the barrel said 180s would be fine but maybe not??? Thought some of you guys might have a good idea.
I am loading with reloader22 1gr under max.

Do you think it would be worth buying a slower burning powder or just give up with the 180s?

Thanks for the help!
