Re: 338 Lapua Case in a model 70 or 700
I am not comfortable using a model 700 for the 30 Wolf. I have never built a Wolf on a 700 action. The bolt and action lugs will prove themselves over the next 10 years with the Ultra Mags. The Seiko style extractor is a definite improvement in one sense, and I must say I would never put my face near one for any length of time without a seriously improved bolt stop.
Dan Lilja is not a fan of the Winchester for this type of application because of the 1 inch diameter threads, the Remington has 1 1/16 inch threads. I agree with Dan on just about everything, this however, is one area where we differ a little bit. I am less concerned about 1/16 of an inch on the barrel tenon, than I am about what the extractor relief does to the bolt face on the Remington design and how that interacts with the counter bore in the barrel tenon of the Remington during an overpressure situation.
There are quite a few people that have told me, "well the Ultra mags don't seem to have any problems". I hope this remains true over the long haul. Remember though, the lapua brass will live about 4000 to 6000 PSI higher than the Ultra mags brass. Don't forget that heavy-duty bolt stop! [img]images/icons/wink.gif[/img]
