I am going to get a 35 whelen this summer, a rem. 700. there are two guns I am looking at, my favorite ( at least for looks and having iron sight from the factory.) is their bdl, but I would have to get a 30'06 and send it to JES to bore it to 35 whelen. which I have no problem with, I trust him. the other is the cdl and is already cvhambered in 35 whelen, but I would have to have the sights installed (135$) and the thing is it is a 1:12 twist barrel and I was wondering is that's too fast for 250-280 gr boolits (max 300... maybe). JES charges 225 to bore the barrel out so it would be close in price either way. so my main question is will cast boolits perform ok with that fast of a twist?. Thanks,Travis
