But back then it was cheap to do macien work and he had access to a lot of matterials
I would recomend the .223 WSSM or the .243 WSSM. Because these are factory chamberings
and they are very fast.
I built a .223 WSSM a while back and did some testing and due to sholder surgery have not
completed all of my testing but hope to soon.
So far I have loaded the 62gr bullets to 3915 ft/sec with no pressure signs and a standard deviation of 0006 ft/sec.
My goal is to push the 40gr Blistic tip to over 4400ft/sec in a 1 in 15 twist 3 grove Lilja.
You can buy a rifle already chamberd in these rounds if you don't want a custom but you
probably cant reach these velocitys.
These days there are so many hot cartriges available a wild cat is not nessary unless you
just want one.
