I have a ruger number 1 in 416 rigby and for my final project at gunsmith school I was thinking of rebarreling it to 375 lapua. It would just be a 338 lapua improved necked up to 375 I think it would duplicate 378 weatherby ballistics without the belt and you could use lapua brass. This wouldnt be a super long range rig only to 5-600 yards if it will hoot accuratley enough. But I think a 300 grain accubond leaving the sation at 2900-3000fps would be some serious oomph and would shoot relativley flat. What do you guys think.
