I was taking a look at a Weatherby Vanguard 30-06 (about 5 years old, so pre series 2) and noticed the internal box magazine length is 3.51", which is considerably longer than the max. cartridge overall length (COL) of the 30-06, which is 3.340".
I was wondering how the 300 WBY and 375 H&H fit and feed in the Vanguard S2 since the max. COL of these cartridges is 3.560" (300 WBY) and 3.600" (375 H&H)?
Looking at the action, I don't see how they managed to do it without somehow lengthening the internal mag box. I'm also thinking enlarging the feed port would be necessary since the opening on the 30-06 (long action) is only 3.335".
I took a look at the 30-06 long action and I'm figuring the longest internal mag length they could fit on the receiver would be about 3.68" (plenty long enough), but some additional machining would be needed to do this. And there would still be the issue of the cramped feed port.
Anyone have a Vanguard in either of these cartridges and care to comment?
 
My .300 Weatherby Vanguard has a 3.555 mag as near as I can tell. Since the .300 has so much freebore it doesn't make any difference. I don't have a Weatherby in .375 but in my experience with the caliber few bullets get close to the lands even in a longer box anyway. I've never seen a factory loaded .375 round that wouldn't fit in any magazine, so I wouldn't worry about it.

Are you shooting factory or handloads in the 300 WBY? It seems a little strange the mag box length is so tight on a factory Weatherby. I do agree with it not making any practical ballistic difference since the WBY has quite a bit of freebore, but I would wonder how feeding would be with handloads close to max. COL.

My .300 Weatherby is one of the few rifles I ever shoot factory loads in; and that's just because it was cheaper to buy the cheapest Weatherby factory ammo than to buy the empty brass. Besides it shoots pretty good, good enough to meet the Vanguard 1" warranty anyway. For handloads I've only really got the 180 Interlock and the 180 Partition on the go, but don't feel too hard done by about it. Both are seated with a COL of about .025" less than mag length which is my habit with rounds that won't reach the lands. Feeding is beyond flawless, there are some expensive brands out there that could learn a thing or two about feeding from a Vanguard. A thing or two about shooting too.
