    Hello I am new to posting on this forum have been reading on it for a while. I am torn between two cartridges. While I have plenty of rifles to do do what I need, 270, 30-06 300 RUM no break, 338 win etc 338Rum with either McMillan A3 adjustable or A3-5 in the works.
    I am looking to build another in either 300 win mag or 7mm rem mag in a McMillan hunters edg stock and jusr can't decide between the two. Looking for a little push, no pun intended

    I don't see any 7mm's in your current list... The 7mm RemMag is a great one, and one of my personal favorites. Been hunting with a 7mmRM for 16 years now, along with many other cartridges & calibers throughout my life, but my "old faithful" is always a 7mmRM. Ballistically, a 7mmRM with an equal weight-for-caliber bullet will do everything a .300WM can/will do. The 7mmRM will also have less recoil, if that matters to you? I know it does to some folks who might be recoil-sensitive or have medical conditions.

    I agree, no .284 in your line up. Go 7mag.

    I agree with the others..... you need a 7mm! With the new 7mm bullets coming down the pipe it breaths new life into the 7mmRm. I was torn with this same devision but after running the numbers at 1,000 yards the 7mm has more velocity, less drop, and less wind drift than the 300. Doing all that with less powder and recoil than the 300...... what's not to like? Only thing it lacks in compared to the 300 is energy.

    And with the heavy Bergers (180, 184, & 195), even that factor is minimized. ;)

    And displacement. Bigger dia bullets make bigger holes. Frontal area does make a diff.

    I agree with the .284 caliber, I have a 7mmRM and a 28 Nosler, if you are going to push the 195 Berger's, then look at some of the larger magnums in the 7mm. The 28 Nosler will push the 195 3000 -3200 fps, the 7mmRM will not get to that velocity.

    Looks like you have the 300 spectrum already covered up. 7 mm and 300WM will do about the same, so flip a coin and go with the chose. Or, be flexible in your thinking and consider something else...6.5 of some choice?

    Welcome to LRH and enjoy!

    Normally, I'd recommend the .300 WM over the 7MM RM but since you provided your current inventory, I too recommend the 7MM RM.

    Yes you do.

    How do the either 2 choices do anything you don't have covered?

    Is the style of rifle going to be something you don't have?

    I will say though, that the current load in my cousins 7mm rem mag is a 180 Berger VLD at 3015 fps using Reloder 26, looking at ballistics, thats not terribly far off of a 195 at 3100, while it's not quite as impressive as the 195, the price of brass in a 28 nosler and the significantly shorter barrel life may offset the extra performance. The 28 is still a great option, but just some more aspects to take into consideration.

    I was not recommending the 28 in particular, but may look at the other ultra magnums, I would also look at the 7STW, 7 RUM, 28. Nosler, etc.

    Why not pick the larger in case capacity,,, this allows you to get things done in the long range shooting and Hunting thing .

    Then tap it kool in the off season.
    Less powder burnt, less barrel wear, more time spent plinking on the fun side .
    Shoot lighter bullets at a less price that saves on funds.

    Exp:

    I shoot a 30/06
    I load even across the board "Less" the powder charge.

    I load hot during harvest season pushing the 178gr Hornady ELD-X @ 2880 ft-per second's,,, then tap it down to 2680 ft-per seconds at general plinking of F Class , the 1 km ,,, and the odd 1700m shoots in the summer.

    That way I get the best of both worlds and a extends mileage out of the rifling.

    I did this same thing with my 300 Weatherby Mag back in the day. The only reason I scaled back is I'm a bush harvester and don't go after critters beyond my hand held shooting skills .
    50 to 200 m's with the option to drop the the poles for 350 to 400 meters "if" the shot per-mits.

    This idea is just an option for those that choose to go this route.

    I have 2 ballistic charts for each cartrage charge, that way I'm good for both categories.

    1 cartrage, 1 rifle, and 2 loads to fill the needs.
