If it is feasible and safe he will tell it to you straight.I would think it is strong enough but Greg will know for sure,I think I would be inclined to make that gun a 223 Ackley and look for a Weatherby in 22.-250 as a donor for the .224Weatherby.Just my 02.I assume you have plenty of brass for the .224W
My buddy had a Weatherby in 22-250 he liked it a bunch,wouldn't sell it to me either
