338 Win Mag or 300 Weatherby
 

I am interested in comparing the accuracy of the 338 Win Mag vs the 300 Weatherby. If I buy the 338, it will more than likely be a Sako 75 SS. As for the 300 Wtby I would consider the Sako or the Accumark. Both are pricey, but I decided that with my next gun price would not be an issue, I just want the best gun I can get for moose and elk hunting. I currently have a 7mm Rem Mag and will never get rid of this gun. It has shot plenty of bull elk for me, but I thought I would try something bigger for those 400-500 yard shots that sometimes have to be made. I realize that within 300 yards the 338 will be just as effective as a 300 weatherby, but I sometimes worry about the accuracy of the 338 when we get into the 400-500 yard range. I have no doubt about it's knockdown ability at that range, but as I mentioned, is the accuracy as dependable as the 300 weatherby at that range? I also worry about the freebore in the weatherby. Will this affect the accuracy? Especially if I am not handloading and will have to buy the expensive weatherby factory ammo. Just to throw more into the mix for comparisons, I have also been looking at the 300 remington ultra mag lately and find it's ballistics very comparable to weatherby, however I am not sure if I want a Remington rifle. But the Sendero sounds like an impressive rifle that may rival the Sako and Weatherby. I would consider this calibre in the Sako, but I have heard that Sako is no longer making the 300 RUM. All feedback is appreciated.

This is a tough decision, you can either choose big knock-down power with good accuracy (338) or great accuracy with added knock-down power (300). This all depends on where in the US u will be using the gun and how open the terrain is. Also a added factor will be the type of game you are going to use this gun for.

RE: 338 Win Mag or 300 Weatherby
 

Accuracy is dependent on the quality and craftmanship in the rifle, the quality and match to the rifle of the ammunition and lastly the skills of the shooter. There is absolutely no evidence that a .300 is more accurate than a .338 mag.....

As long as you're not hunting dangerous game (big bears) the power levels of each cartridge is equivalent to the other. Flip a coin.

At this point I'd recommend a custom rifle. Find an older Remington BDL, Sako, Win-70, Howa,whatever trips your trigger and have it fitted with a Lilya, Hart, Shilen.....etc barrel and bedded in a McMillan or Bordon Rimrock stock. Blueprint the action and install your favorite Leupold scope and head for the range.

I'd consider the .300 Weatherby because it's a little more versatile but the ..338 mag is also a fine big game round.

RE: 338 Win Mag or 300 Weatherby
 

There is no clear answer here.It depends on the game and conditions that you will hunt.If you don't handload I would choose the 300win mag over the 300wby due to the much better selection of factory rounds.If you do handload,I would go with the 300ultramag as it does offer a little more velocity with similar recoil to the 300wby.

RE: 338 Win Mag or 300 Weatherby
 

If you have the time to practice and the skill to make those 400-500yd you mentioned I would probably go with the 300Wby over the 338. The flatter trajectory of the Weatherby would take some of the guess work out of those long shots. If you had a 300yd limit then I would back the 338, hard to beat those larger, heavier bullets from 300yards and closer..

RE: 338 Win Mag or 300 Weatherby
 

For shooting game at that range I think your 7 mag is as good as anything. Never been in a position where I HAD to take a shot like that. My shots are always my choice.

RE: 338 Win Mag or 300 Weatherby
 

accuracy depends on the rifle's and loads quality. If the 338 mag is accurate at a 100yds then it will probaly accurate out to as far as you can shoot it. The thing would boil down to tajectory between the two. They both have optimum energy. The 300 weatherby would give you a flatter trajectory. The down side to it is the price of the cartridges.

RE: 338 Win Mag or 300 Weatherby
 

Obtain the best of both cartridges, and go for Weatherby Mark V Accumark in .340 Wby. Mag., or a Sako 75 Hunter or Sako 75 Deluxe Rifle in .340 Wby. Mag.

I have a Weatherby Mark V Sporter in .340 Wby. Mag., and it will shoot three shot groups under .50" at 100 yds. as long as I do my part. It dosen't seem the freebore has had negative affects on the rifle.

Good luck.

RE: 338 Win Mag or 300 Weatherby
 

RDJ -- go to Accuratereloading and look at the Medium Bore Forum.. on page 2 there is a SEndero vs Sako thread. Look at the targets one of the posters put on view his name is POP its a .675 5 shot target at 300 yards with a 300 ultramag Sako 75 SS. That should be all you need to see.

RE: 338 Win Mag or 300 Weatherby
 

Yea, but pop also said his 700 LSS did .5" groups and now after selling it to another AR member, he says the Sako is a much more accurate gun.

I am not a big Weatherby guy. I just don't like the freebore. Yea, I have seen accurate ones, but the ones I have worked up loads for are very hard to find a good load for. I like the 300RUM much better. No belt and less freebore. I also am a 338win mag fan. Either one is great.

RE: 338 Win Mag or 300 Weatherby
 

I would probably lean twards the 300 WBY. While it doesn't have the factory selection of the 338 Win, it's not too bad. Definitely more than the 300 RUM that you also mentioned.

RE: 338 Win Mag or 300 Weatherby
 

Yea at 50 dollars a box for 300wby. Wow, what a deal.

RE: 338 Win Mag or 300 Weatherby
 

I would not have any qualms about owning a 300 RUM in a Sako 75 and after reading that thread in AR my feelings have been justified ( YES BC the group was .675 at 300 yards a five shot group with a 300 RUM, The LSS shot .75 at 100 yards). Too many people own both and have nothing but praises for them. I have owned a number of Weatherbys and they simply cannot touch a Sako in overall quality/accuracy or a Remington in accuracy. You may have to almost spend as much as a weatherby tuning a Remington but it will shoot . I think the Sendero is way too much gun to lug around Elk hunting or any big game hunting where a lot of climbing is involved , you'll use it one hunt and get rid of it. I used to be a factory ammo shooter a few years back..Anytime I bought a new rifle I would go out and buy 10 boxes of premium ammo in that caliber and 10 boxes of cheap stuff to shoot offhand practice with using a total of sixteen boxes in practice and then having 4 boxes or so laying around for the hunt. When it came to Weatherbys this was a very expensive proposition and until recently I had a small mountain of various Weatherby brass in my Garage. The Weatherbys shot better then average and were consistent and trouble free but they cannot touch a 700 or a 75 accuracywise just no way.

RE: 338 Win Mag or 300 Weatherby
 

bc- I didn't know we were bargain hunting.

RE: 338 Win Mag or 300 Weatherby
 

Well, not really bargain hunting so much as there comes a point where it becomes rediculus to shoot. The 30 dollars/box for the RUM is about my limit. The 50 dollars/100 pieces of brass is about my upper limit for a RUM. But with weatherby, they have gone over my personal, and I bet others limit. Especially when there there is other calibers that will match the performance. In other words for me, the ends don't justify the means.

RE: 338 Win Mag or 300 Weatherby
 

The 300 RUM would out perform both calibers.

RE: 338 Win Mag or 300 Weatherby
 

IMO the 300 Weatherby is one of the best "do everything" cartridges made.
I can buy ammo at $30.00 a box or roll my own with bullets from 150 gr. to 220 gr.
It's accurate, long range when need be, and just all-around good.
Again this MO.:D
Good luck and good hunting

RE: 338 Win Mag or 300 Weatherby
 

I just bought a box of 300wby 180grains for $20.00. I didnt think the price was too bad. They had 150 grains as well.

RE: 338 Win Mag or 300 Weatherby
 

What brand was that burnie? If weatherby, then thats not that bad at all.

RE: 338 Win Mag or 300 Weatherby
 

300 wby mag

RE: 338 Win Mag or 300 Weatherby
 

300 WBY all the way!!!!!!

RE: 338 Win Mag or 300 Weatherby
 

Sierra GameKing Boat-Tail SP. I load my own. Got these to break in my new gun. I have seen the Remington express for around $26.00 at Academy sporting goods. I think since Walmart started selling guns in 300 wby, more people are buying them. Walmart carries 180 grain, not sure the brand for around $23.00.
