There are some that have never owned a Weatherby that condem them because of too much free bore. There are some that condem them as over priced. There are some that own them that are very satisified with them and have had great sucess with them. There are a few that have had them and had bad experience with them, pretty much the same as any brand. If you are planning on having it customized there is a lot more options for a Remington or Savage.

I have a 257 Wby. and found that with the 115gr. X-Bullet I could consistantly get around a 3/4" group, some times less. When I had a Rem 700 VS-SF in 22-250 I ususally got groups ranging from 1/2 - 3/4" depending on ammo, wind and the loose nut on the trigger.

with a little tweaking like trigger work , bedding and barrel floating and with load development with a better bullet than the X bullet you should be able to get it in the 1/2 moa range.

I've seen a few shoot realy well with the above mentioned work , one would shoot in the 1/4 moa range when partly necksized fireformed cases and nosler ballistic tip bullets.

I bought one new in '99 7STW. I didn't have much room to brag about regarding accuracy. First rifle I bought to get into LR and since learned to go with the 700. Remmy has much more to offer in after market parts to tweak accuracy. The WBY was a beautiful rifle, but not consistant even with loads that were prepped to benchrest standards. I'm sure there are many accurate WBY's out there, mine wasnt one of them.

I had one and my $395 Remington in the same caliber would shoot much better. Played with the Accumark with 4 or 5 powders and different bullets and no improvement. Got feed up and sold it cheap. I thought it might be the scope, but it shot well on my Remington 25-06 Sendero I can not rule out the mounts since I did not change them out while trying to get the Accumark to shoot. Just my expeience.

Weatherby guarantees 1&1/2 MOA with there Accumark to start with.

I am a big Remingtion fan but they dont make any such claims nether
does Win,sako,browning,Savage or any other that I know of using there
factory ammunition.

If you buy one that does'nt shoot 1&1/2 MOA you can send it back.

But the weatherby guy's will all tell you that the best way to make any
Mark 5 shoot is to adjust the tip pressure.

If you free float the small tapered barrels they may not shoot as well as
before.(this is what weatherby does if you send it back.

The weatherby action is very well made , strong and requires very little
blue printing compaired to most other actions.

As far as freebore if the action is well fit to the barrel and headspace
is held to a minimun .001" accurace doesent suffer.

I like to use the Remingtion action for all of the standard mag (.534 bolt
face or smaller) and the Weatherby Mark 5 for cartridges with case heads
around .600"or larger.

Also the Mark 5 mag well is .100" longer , A plus for big bullets.

I have found the Accumarks to be one of the most consitantly accurate rifles made. I have worked on several Senderos that have been either really good or really bad. I have yet to find an out of the box Accumark that won't shoot under 1" with factory ammo. I have 3 Accumarks of my own and they are all bedded now with the factory triggers adjusted down to just under 1 pound and all of mine shoot under 1/2 with several different loads and with there prefered loads better than that. My best group so far is 3" at 885 yards off a field rest. Normal still conditions and a goodrest 1 1/2" groups at 300 yards is what I expect from an Accumark. 257Wby, 300Wby and 338-378Wby seem to be the most popular ones. If your shopping the Accubrake is a great option on anything bigger than a 257Wby. I even wish my 257's had them.
