rifle/caliber help. 7mm,30,338??

[setandglass]

I want to replace my 300 wby mag just not doing what i want it to. I hunt ELK and Mule in CO @ 8000 feet. My problem I need a caliber that will kill elk at
1000 all my shoots run 500 to 1000, most will be 700 and 800 tho.

My buddy has a 7mm sendero ultra mag 180 berger @3150 on retumbo.gun)

I would like to know what you guys think about that set up for elk at 1000 (2088fps/1742 energy @ 1000) reason I'm considering buyin one.

But I'm torn with the 338 and say a 225 or 250 bullet. I dont think the 300 berger is for me been running the number jujst to much drop I believe.

Any help will be fine. not looking to buy a full custome so gun I nee is something I can run out and buy and have alittle work done.
Guns in my mind 338 or 7mm sendero ultra mag, AR30 338 lapu.
My 300 wby is just not putting up the numbers 210 bergers @ 2750 best load. max speed so far 2850. When ran by the 7mm its way behind.

My vote for a new rifle would be for the 338 rum. 1000 yards and elk =338
As far as your 300 weatherby is concerned, your velocity is way under what that round is capable of. I can run much higher speeds than that out of my 300 wsm. I load for a 300 weatherby and I am doing well over 3000 with 208gr amaxes. Why don't you post your load and powders tried along with your gun and barrel length and I bet some of the guys here can help you out.

This sound off to me. Try the 230g Berger OTM to get the results you want out of your 300wby. What scope are you running? I just got a 338 RUM barrel for my sendero and I will be pushing the 300g Berger.

Thanks for the reply I will try to get that info out. My gun is the mark V ultralight. Barrel length is 25. Was 26 but the gun had a laser port done on it I didn"t like so it was cut off and muzzle break was added. Any suggested loads. I'm trying to shoot the bergers to get the most BC. trining several powders didnt get to try the retumbo yet. Was shooting the factory 180 accubonds but they wasn't accurate enough to shoot past 700 yards. Huskamaw scope

There is a problem with your 300 wby. My 300 win with a 28" tube sends the 210 Bergers @ 2995 with H-1000 at 4100 ft. and you are at 8000 with a WBY? Most all the 300 wins I mess with, with 26" tubes are at 2850 plus.

I don't understand your concern with a 338 and a 300 gr bullet and " too much drop" You do realize this is the go to elk rifle and bullet for many many users here and we take many elk to 1000 and some beyond each year.

You are dialing turrets arent you?

Your Weatherby velocity seems really low despite the 25" barrel. I shoot a .30-8mm Mag with a 27 1/2" barrel and it pushes 210's at 3100fps and a friend has a .300 win mag that shoots 2960fps with 210's in a 26" Sendero.

Sorry I'm shooting my gun at 2350 ele. I hunt at 8000 sorry about that. my fastest load so far is 2850 with the 210 berger. gun is like new less than 100 rounds threw it.

yes I'm dialing turrets.(no cash for nightforce at this time) yes the drop of the 300 gr in the 338.

HAndloading is essental to this sport imo. If you want to shoot the berger make sure you read the artical in my signature line. Also I am hearing that the OTMs are not sensitive to seating depth.

 

[setandglass]

I agree reloading is the only way to go.(read that post already too) Anybody with thought about the 7mm 180 berger @ 3150 for elk and distance? At 1000yards @ 8000 feet it looks like this 2088fps 1742 energy

 

[IdahoCTD]

I shoot at 2700' elevation and hunt from 6000' up to 9000'+. I shoot Matrix bullets in mine because they were more accurate and less sensitive to changes in seating depth. I'd try H-1000 or 7828 for your Weatherby if you haven't already. I shoot R-22 in mine but R-22 is more temperature sensitive. R-22 and 7828 are really close and in most of my 8mm mag based cases (7STW, 30-8mm Mag, and .338 Baer's) I shoot 1 grain more 7828 and 4 more grains of H-1000 then R-22.

If I were an elk hunter...a 338 in some form would be what Id reach for first

A .30 caliber with heavy bullets doesn't give up a whole lot to a .338 with light bullets other than bullet diameter. For example at his 8000' elevation my .30-8mm still has over 2000fps and 2000fpe with a mv of 3100fps and 210's. A .338 shooting 225gr Nosler AB at 3200fps is less than 2000fps and fpe. With the Cutting Edge 225's it's about 150 fps more and 200fpe more. 338's and up are in a league of their own with the heavy bullets.

If I was in your shoes I'd have a custom barrel put on your .300 Weatherby if you can find a smith that can turn it around fairly quickly. Most of the time bugholes.com has .30 cal Brux #4 or 5 sporter and Rem. Varm. barrels in stock. You could even change to a different caliber if you want to like .300RUM or .338RUM. You would end up with a better rifle than most of the over the counter guns provided the smith does his job correctly. Just my .02 worth.
