30 cal 220gr HPBT bullets viable for .308?

[RooftopKorean]

Anyone know if 220gr HPBT in 30 cal is viable to reload for .308?

I picked up three boxes of factory seconds a while back from MidwayUSA.

In comparison, Hornady A-Max 168gr are 1.27044 in length vs. MidwayUSA Factory Seconds 1.4955.

Yes you can. Use powder and bullet manufacturer starting loads.
The issue is going to be stabilizing them depending what rate of twist you have.
Alao certain match chamberings and magazines.will.allow you to runa tad longer COAL.

220's will stabilize in a 1-9" twist barrel. I haven't tried them in the more common 1-10" barrels, but i wouldn't hesitate to try them.

Personally i feel that’s a little heavy for 308. I use 220s in my 300WM for long range shooting and that can push then at about 2800 with a long barrel and 70+ grains of Reloader 33 (i think this are the numbers, i dont have my data in front of me). I think 308 is going to have a tough time moving that heavy a bullet. I use 165s and 175s in my 308, and those push at about the same fps (2800) with a much smaller powder load. However it all depends on your application.

Thanks for all the info, I'll just save them to reload my friends 300WM then.
