.303 British primer pocket conversion.

You should have gotten the 308 version of the #4 or just pick up some commercial ammo that is boxer primed and load the snot out of it

I did not know what a .308 was and it certainly was not on my list. But paying $59.99 for a rifle and the ammo was priced at $1.99 and $2.99 for a 20 rd box was a good purchase for me back in the day. I think Most if not all of my boxes are blue and fuzzy (kinda) cardboard and they say sellior and belliot whatever on them.

Damn. I can get that in .308? That thing is a freaking crater-maker for sure. It will shoot the piss outta can of lima beans at 25 yards... **** goes flying EVERYWHERE...

Yep, picked one up in 308 15+ years ago for $50 and 1000 rounds of 308 ammo for $79. The good old days...

This guy used copper tubing to fill the gap.
The guys is using lead cast, so it's low pressure.
I don't know how its gonna hold up under regular pressure.
Seems like lot of work though.

I generally find it simpler to drill out the berdan pocket to fit a shotshell primer.
shotshell primers are about .240 and will even work in the .250 and .254 holes as the shotshell primer is long enough to be held by the case web -
They work fine for most cast loads --
However, not worth the effort for me if good boxer case available --
