I know there is a lot of knowledge on this site so im hoping that someone can sway me one way or another.

First of all, im out west in Idaho and hunt it all from coues deer to moose. i recently sold a savage 300 ultramag and am now looking at something new. What i didnt like was the length of the barrel at 26 inches + a break but it did shoot sweet.

i am looking at a 300 weatherby sub MOA with a 24 inch barrel for 750.00 range or the sendero 300 ultra mag in the 1100-1200 range with a 26 inch barrel.

Can someone sway me one way or the other? besides the weight,price and barrel length. The weatherby wins in all categories there. price isnt that big of a deal but if they are equal, of course id like the extra coin.

Are there any pros and cons that are more in depth that a novice would overlook?

Thanks guys for any input in helping with the decision.
 
I am not a wby fan but the 300 wby has some advantages, less powder, almost identical ballistics, the disadvantage is wby's have short magazine boxes and free bore, If you plan to shoot barnes bullets that probably wont matter much as they are not very seating depth sensitive. I have owned both rifles you are talking about and my vote goes to the wby

You leave out a very important part of the equaition which is, realistically what are the maximum ranges you are planning to shoot?

If it's sub 600yards then go with a 300wsm in something like the winchester coyote outback.

If 1,000yds is in fact reasonable for you then you need to stick with something like the Rum and the Sendero platform.

If you want to eek out every fps and have the best combination of precision, range, and FPS/Energy then you need the big case, lots of powder, and enough barrel length and weight to take advantage of it.

Shoot at animals, probably 500 tops but would like to shoot targets up to 800 or a 1000 for fun.

300WM or 300wsm then would do all you need then. As for barrel length/diameter for precision in general all else being equal the longer heavier barrels will give you better results.

It's really tought to beat The Sendero's without spending a hell of a lot more but I love the weight of the Winchester Mod 70 coyote series and I think they are making them in both the 300wsm and 300wm now. That 24" barrel which finishes at .75" is really sweet.

300 WBY (even at 24") and 300 RUM are both capable at 1k and beyond.

The Sub-Moa WBY and Sendero are both capable as well.

Sendero has a slight edge in both categories, but not a huge difference.

I'd be looking at the 230 Berger OTM, or 225 Hornady BTHP. But, the 210 VLD or 208 AMAX are popular as well. ...and, H1000 or Retumbo. Jeff (Broz) has posted impressive results with the 230 OTM's out of 300WM and RUM.

Either rifle can succeed. The key will be the supporting gear (e.g. optics, LRF, wind/weather, ballistics calc), and ultimately one's practice/dedication to the objective.

I'm getting very good results with my Rum out to 1,120 shooting the 180gr Siroccos. I keep wishing they'd make a 200-210gr .30 cal since I love the terminal ballistics of the Sirocco.

As for the above I'm just picking those ranges as general rules of thumb.

I love the Scirocco.

I wonder if pressure and fouling are concerns with making them longer/heavier.

They already have a long bearing surface and softer (all copper) jacket. ...not really a problem for hunting.

In any case...
"Shoot at animals, probably 500 tops but would like to shoot targets up to 800 or a 1000 for fun."
...isn't going to be a problem for any of the rifles mentioned thus far with a little load development and range time.

That's not what they tell me. Mainly it's a matter of them being a small family company and the demand for the heavy for caliber LR bullets just is not great enough to justify the expense of gearing up to produce them.

As good as they perform though it really makes me wish they'd produce a 165-175gr 7mm and something in the 200-210gr range for the 30's.
 
Between those two I would go with the 300 wby sub moa. Much lighter and easier handling and can be shot without a break. You have the guarantee it will shoot or give it back to wby. You have plenty for 1000 yards with the wby. Just not that much difference to the RUM. About 125 fps on average.

Another option to save a few more dollars would be the Tikka T3 Light. That one 300 Winchester will also work for you. I have six of the Tikkas and all shoot extremely well.
