Today in Sportsmans Wharehouse while looking at scopes, I noticed some fine-looking Weatherby rifles. The one that I noticed the most was the Vanguard Sub-Moa. It was in stainless with the black webbed stock. The only calibers they had them in were the 270 WSM and 300 WSM. The price of the ammo is nearly identical so that wouldn't matter, but what about the ballistics of each of them?

Also, has anyone shot one of these and do they actually get within .99" like Weatherby says? What would the recoil be like coming from each of the cartridges - the gun was pretty light so I was wondering about this.

One last question, is $719 NIB a good price for this?

I wouldn't call a three shot group less than an inch at 100 particularly noteworthy. I have heard that the 270 and 300 are the only WSMs that are close to what they are advertised ballistically, but I've never known anyone who could reload and get the ballistics that are advertised. Velocity is always slower. You could get the same gun with "Howa" stamped on it for a lot less. For that price, I'd feel a lot better about a CZ.

the sub-moa vanguards don't do much for me, but that's just a personal preference.

the 300 wsm is a great cartridge, and a good one to handload for.

it recoils like, well, a 300 mag. i don't find the recoil particularly offensive, but a new or casual shooter will likely find it obnoxious. mine just ate a brand new pentax scope in 14 shots (lesson to be learned here is that there is enough recoil to destroy low end scopes quickly).

bottom line is i like the 300 wsm quite a bit, but recognize it may not be for everybody.

i have no experience w/ the particular rifle you are looking at, though.

the 270 wsm, actually recoils like the origional 270, and with all the wsm's, gains the most in b.c. and velocity. In short, it is as good as advertised, plus a bit more. I would go with this first and foremost, or , do a whole new thing; buy 300 wsm brass, by 160 or 180 grain 7mm bullets, and make you a wildcat rifle in 7-300wsm. A super great round, that is doing some stunning things on the 1000 yd lines.

The Weatherby Sub MOA line does 3 shot sub 1" groups, all day long. I know of quite a few people that own them. The best part is, if the gun will not do it, send it in, and Weatherby will fix it, or replace it. They have some of the best customer service to be had. If there were one for $719 in these parts, I would be buying it as we speak. The only doubts that I have in buying a Vanguard Sub MOA is the fact that I have a Vanguard Synthetic 7mm Rem Mag, that I have shooting consistant 3 shot groups in the .4s. 10 shot groups are still under 3/4".

As for the cartriges, the .270wsm is a little more punch than 270 win, but not bad at all. As for my personal experience with the .300wsm, in my mind it had more punch than a .300 win, though I know they are ballistically the same. If I had to choose, I would take the .270wsm. Nothing in NA will survive it within 250 yards. I would suggest you hand load for either cartrige in order of not paying way to much for ammo.

My business partner bought a MOA Vanguard .300WSM to take to Africa next month. I have a .270WSM in a stainless Winchester 70 Ultimate Shadow Classic which shoots at least as well. We both have Leupold 2-8 VX 3 with B&C reticules. The 270WSM recoils considerably less. The .300 WSM recoils less than a similar .300 Win Mag a friend is taking to africa, for what it's worth, seems like the difference is more muzzle blast in the .300 win mag too. We are all using Federal Premium with Nosler Partitions. 150 grain in my .270 and 180s in the .300s.

The SUB-MOA Vanguard are Vanguard that fired exceptional test groups and were then refitted with SUB-MOA stocks and features. Weatherby selects guns that fire 0.5 or less test targets so they can easily guarantee 1 inch MOA accuracy @ 100 Yards.

I wouldn't call a three shot group less than an inch at 100 particularly noteworthy.

+1. My Armalite M-15A2 Carbine is just over MOA (1.3"@100) with ball ammo from a bagged rest. Hardly a precision unit there.

I also don't consider 3 shots a group for accuracy purposes. 3 is a good number when sighting in to conserve ammo. 5 groups of 5 shots minimum for an accuracy claim.

Calculate 300 wsm ballistics and 270 wsm ballistics at the click of a button, and see how they compare with 300 win mag and 270 ballistics using Shoot! ballistics software.The new 300 wsm and 270 wsm cartridges from Winchester are popular among hunters. When you compare 270 ballistics against 270 wsm ballistics, the latter cartridge beats the former classic by roughly 200 fps (shooting the same 130gr projectile).The 300 wsm, on the other hand, duplicates 300 win mag ballistics, but with less powder and much shorter cartridge length. This results in less felt recoil too.The 300 wsm and 270 wsm ballistics are impressive, but what makes them even more appealing when compared to a regular 270 or 300 win mag, is the short-action length and therefore more compact, handier rifle.

Edit:Just realized that my reply did not address the OP.

With a WSM round, sub-MOA at 100yds should be considered standard, not exceptional. The .300 WSM has the same ballistics as the .300 Win Mag, but in a short action casing, making it more user friendly...especially if you're lugging the gun and ammo around all day over terrain; or watching what you're aiming at through the scope whilst chambering a round.

Another thing to keep in mind is that the wsm's are not belted compared to most other mags. You should, should get more firings out of the case if you reload. Also being short and fat they should, all things being equal, be slightly more accurate than the regular mags.
