    After 29 years of killing prairie dogs, coyotes, antelope, mule deer and elk with a 7mm RM, I bought a .300WM to see what I was missing.

    Turns out the .300WM doesn't kill elk any faster or deader, but it does kick considerably more. That said, I like the .300WM and have used it more than the 7mm RM for elk since getting it in 2004.

    If one lets the barrel cool a bit between strings, 50 rounds in a session would take many hours. I just got home from spending 2 hours in a wheat field in 75º beautiful weather, with two rifles, with a homemade barrel cooler, and I still only fired 33 rounds. That was pretty much as fast as I could get it done, without firing a string on a barrel that was more than "mildly warm" to the touch.

    As for recoil tolerance, "50 rounds" is meaningless anyway. 1 painful shot is enough to throw off even someone like me, who is more recoil tolerant than anyone I know. I printed a 1.5 MOA group, shooting prone, with my buddies 7.5 lb, iron sighted Marlin Guide Gun, shooting 405 gr gas check cast bullets at 2000 fps. Probably the hardest group I've ever shot. I was able to concentrate my way through it, but heysoos chreesto, every trigger pull was a struggle.

    IMO, if you want power and good groups, you must have a good muzzle brake. I have a 270 Win Marlin X7 unbraked (9 lbs outfitted) and a 300 WM Savage LRH braked (11 lbs outfitted), both with squishy modern recoil pads and synthetic stocks. The 270 kicks SUBSTANTIALLY harder.

    I don't see the drawback to brakes, other than an extra 2" of rifle and more dust kickup. Complaining about the noise makes no sense. I NEVER shoot without ear pro, and can't imagine why anyone would, even in a hunting situation. And if that elk pops out so quick you can't ear up, the damage from braked/unbraked for one shot in a lifetime isn't that much different.

    You quoted me so I will add that my 50 rounds of 7mm mentioned was a over full day of shooting.

    And yes I totally agree with you and I don't see any reason for NOT using a muzzle break. I even have one on my 15lb Savage M12 in 204 Ruger that I use for prairie dogs....my sight pic barely moves and I can see the dog splatter through the scope.

    I'm not ashamed to say that I hate recoil and shoot much better with a light recoiling rifle....pistols too

    I honestly enjoy shooting punishing guns, but it's different "enjoyment". Some folks will run 5 miles up a hill and suffer and sweat, and say it's great. Something like that I suppose. Makes me feel "manly and tough" that I can shoot my 4 5/8" 454 Casull and little 45-70 lever guns without flinching (you want punishing, I have a 454 Casull Rossi 92 that weighs 5.5 lbs and has a buttpad made of something just a smidge harder than tire rubber.) :confused:

    That being said, a mid-size rifle with a sweet brake and recoil pad, that will shoot lights out and deliver big energy without pain and suffering, is just as wonderful or more than a fire breathing short barreled super magnum revolver that leaves your palm sore for two days.

    We will be on the range early in the morning till as late as I feel it necessary. Heat index well above 100 is another daily event here.

    Hey vitamondo, did you buy it yet? Curious as to your decision.
    I have a 7mm rem mag
    300 winmag
    300 weatherby
    The 7 mag is my favorite to shoot. If i was hunting big bears i would take out one of the 300’s. But prefer the 7. It’s a pussycat to shoot.

    Hello Oldschool280.
    I still haven't bought it.
    This week I want to have the 7mm rifle in my hands, how it feels.
    Then I will decide

    Curious if the hornady pro hunter or superformance ammo is available over there. 162 eldx or even a 175?

    Your weird ! Lol I can say that, cause I'm the same way ! Once upon a time, I took my new to me Ruger M77 300WM, my Winchester M88 308, and my Ruger Super Blackhawk 44RM to the range. 140rds for the 300, 200rds for the 308, and 100 for the pistol. I was there all day, and I was mad when I left, cause I was out of ammo!! Now days, I try to load 40 rds at a time for my 338-378 Weatherby, and I burn it all before I leave the range. She's a little more pricey to run, tho !

    Soooo 180 grain bullets out of a hot loaded 7mmm ladies cal recoils less than 180 loaded out of a 300 Winchester Mag.....hmmm I have shot both and with equal bullet weights (or as close as possible) recoil was very similar. Note: equal bullet weights. Its only when we start looking at extreme weight differences the recoil becomes a factor. My shooting partners 7mm Winchester Model 70 ( assuming stock design- wood) definately recoils more (apparent) than my fiberglass stocked 300 Win. Stock design? Gun weight? all factors for sure. Having the option to load up 212 grain ELDX or 225 grain for longer ranges and harder hitting, an advantage, of course, enough to sway the average hunter, maybe not. But its an advantage.

    I think the point is that a heavy-hot loaded 300 mag is going to recoil more than a heavy-hot loaded 7mm....weight of rifle being equal.

    With bullets of equal weight? I don't think so, bumping up the bullet weight will increase felt recoil, yes but then the bullet is bigger, hits harder, and hence the advantage, all things being equal....I would rather hit with a 212 grain bullet than a 180 7mm but that's my preference and it hits harder period! Most of us use a muzzle brake so the point is mute.
