If its true that is that strong its a shame that almost everyone thats been rebuilt here around ends at 8x57r.

I was initially wanting to build something to shoot 9,3mm bullets (and will so do also) with the intention to build a ,375 if the 9,3 works well(and if I'm capable of it). Thats why i'm interest to here from anyone that alredy rebuild one to know how much force it can live with.

But if it can hold it why not a 450NE 3,5"
