Re: 300 RUM or 7mm with 180 bergers at 3000 fps

I have both and would say for what you have said your uses will be, go with the 7mm. 168 berger VLD's are devastating on elk out to 1000 yards. The 300RUM is an amazing gun, but 7mm is all around one of the best in my view.

Re: 300 RUM or 7mm with 180 bergers at 3000 fps

I think the best question to ask is how bad do you want your shoulder to hurt and why? In my opinion the 300 RUM is an "ego booster", that's it!

I shoot the 180 Bergers and my brother-in-law is shooting the 210's out of his 300 RUM. My gun is a bit heavier, but, compared to another 7RUM, also a Sendero, the 300 kicks ALOT more.

The 7mm LRM is the cartridge that I would go with, readily available brass and dies now. The performance you are looking for, and won't beat you up so bad that you may actually shoot it enough to get good with it.

Even if you don't want to go "Wildcat" the 7mm RM is great! The bullet can be seated out properly (unlike the 300), which makes a HUGE difference in inherent accuracy, and will give you the performance you are looking for and then some. I would suggest a smaller Leade angle if you can find a reamer with one, but that is just me.

The bottom line is you don't need that big of a bullet and unless you just want something to talk about in camp that will make you look good go with the 7mm. Also, your shoulder WILL appreciate it!

Re: 300 RUM or 7mm with 180 bergers at 3000 fps

[QUOTE=MontanaRifleman;874209]I just wasted 60 seconds of my life reading this post.

What I was trying to say is the 300 RUM shooting a 210gr. bullet (so that B.C.'s are even close) will kick noticeably harder than the 180gr. 7mm in the same gun.

Most people can not shoot a big .308 without a muzzle break and not develop a flinch.

As for seating depth that is a whole other discussion, but the bottom line is that cartridges that don't have the bullet deep seated are easier to develop a loads for and are more accurate.

Most serious LR shooters, especially LR hunitng shooters, use muzzle brakes. I have a muzzle brake on my 6-284. Reason being, it helps tremendously in spotting my own shots. It is also much more pleasant. I have put a lot of rounds through a 7RM and after about 20 rounds on the bench I was flinching. IMO, the recoil argument is a non-factor in LR shooting. Bigger cartridges shooting larger higher BC bullets faster are more advantageous for LR work, especially hunting for obvious reasons. If a person chooses not to use a brake that's their choice and that's fine but as far as I'm concerned it's a self imposed handicap.

Seating depth is not a problem in the 300 RUM in an appropriate action and an appropriately throated chamber with an appropriate mag box. I seat the 230 Hybrids to the lands and they fit the mag box.

The muzzle brake argument is fine, I personally don't like them, because they are super loud, and suppressors are pretty expensive, but that's just me.

On your other points though, are you pushing a 230 out of the RUM anywhere near 3000 fps? If you are, and you are going to use a brake, hell yeah bigger bullets going faster are better. Just go with a 375 AM and call it a day!

Second, what magazine box are you using and what is your COAL that fits without the any more than the boat-tail being seated below the shoulder / neck junction? Just so that we are all on the same page.

Like I said before these are just my two cents. I know that I have not shot nearly as much as a lot of the other people on here.
