    Which caliber would be best.

    .300 MAG

    7MM

    I can get a 7MM rifle for only 300$ CND...

    I've been hunting for 4 years now and I always been hunting with my grand-fathers .308 (semi-auto) last year while hunting the moose at our camp with the boys...on opening day 1hour after.....this 2.5 year old buck is standing in front of me...

    SO I shoot once , twice and once I try to get him a third tim (he was running) the rifle's mechanic jams (????) so anyways after hours of search we founf the moose dead. lucky me!!

    So this year I did the huge error of going back to hunt with the same .308 Rifle...so sacred it would pull the same stunt as last year (jamming)



    So now im in for a bigger caliber

    either a .300 mag (remington) ...theres one that was 999.99$ reg. on sale for 599$....might getting her..(bolt-action)

    or a good friend of mine is selling his 7MM rifle...(about 10 years old) ....shes bolt-action...shoots super good...and comes with a 2 year old bushnell scope


    so anyways...should I spare the extra 400-500hundred and get the brand new .300 MAG or just try his 7MM


    which caliber is bigger? which caliber gives the longuest shot??


    need help!!..

    p.s. im a first timer here...

    im from Quebec, Canada.

    love to hunt...

    Well you can shoot a heavier bullet with the .300, but I know several hunters who use the 7mm Mag for African plains game.

    I'm also moving this to the RIFLE forum where it belongs...

    I'll warn you the .300 has a bit of a kick... but it's a solid caliber for bigger game. Your friend's rifle... you didn't mention the brand, but if it shoots less that 1 inch groups of three shots at 100 yards it's accurate enough. If you prefer his rifle, by all means the pice seems like a bargain.

    There are no magic bullet/rifle/scope combos... each hunter makes up his own mind as to what works/fits best for him.

    The last time I decided to buy another rifle, I made a point to buy it new and set it up the way I wanted. You can buy a new Savage in 7mm Mag OR .300 WinMag for well under the price of that Remington. And Savage makes a good quality rifle.

    personally I would get the 300 Win. Mag but the 7MM Remington Mag would be almost as good...both would get the job done easily..

    on foot on the ground in brown bear and moose country I'd go with a 300 or a 338. Bolt guns are highly reliable, but slow depending on shooter and position( running like hell trying to reload and rechamber could not be fun) a smaller bullet may expand, but a bigger bullet will never shrink. For a backup/camp defense gun I'd probably have a .308 FAL with a 20 round mag and irons....

    Willie that would be illegal (FAL + 20 rd mag) in most hunting camps in the lower 48.

    7mm or 300 mag?

    Hmmmm...over the years i've had many different firearms. Most i traded off for sometrhing nicer or maybe they didn't shoot well. Currently I shoot a couple of 7mm Rem Mags. My favorite is a Browning BAR Safari semi-auto with BOSS, topped with a Leupold 50mm 3-9x scope, followed by a Browning A-Bolt with a leupold 44mm 3-9x scope. The BAR has virtually very little recoil but it is heavy at about 12 #. My brother bought a Rem 700 chambered in 300 RUM, now that rifle will punish you, last deer season after he shot a few rounds i had to spin him counterclockwise to get him out of the ground. In short, every man has to decide for himself what his needs,wants, and capacity for pain are.

    Heh, plus you need to be allowed to P&A prohibited weapons to get a FAL.

    "well...whats the difference between the

    .300 REM. MAG and the .300 WIN. MAG ????"

    I'm no expert, but I was under the impression that it was business competition. and Winchester is winning. They all came out with a lot of new cartridges, and they all came out with cartridges to compete with the other company's cartridges. Aiui. IIRC you see the same trivial differences between cartridges with a lot of 6.5's.

    There's a 300 Winchester Magnum, a 300 Weatherby Magnum and 300 Remington Ultra Magnum/RUM. Below is a link where you can see the difference in Ballistics.

    ...

    and which caliber would be best for moose, deer, black bear hunting?

    .300 MAG (REMINGTON) or a unknowed 7MM that is mint and shoots perfect (used) Ill go and see her this weekend and bring you guys the brand, year, and even a picture if I can.


    both bolt-action. the guy is a friend of the family....I first heard he had a .300 mag and when I called him he said it was a 7MM...

    which one shoots further?

    I need help! Im undecided and dont know if I should buy this guy's Gun...

    the reason he's selling it his because his wife is sick from cancer and they just morgaged their house. sold their second car (no insurance) the guy is pretty desprit but I dont think he cares since he still owns a .308 and a 30-06...I feel bad giving him only 300$ for it..apparently she is worth well over 500$...but all I want to know is...is a 10 year old 7MM compatible with a 2004 .300 mag. (remington)

    This really isn't an appropriate question.

    If what you are interested in is which one shoots "flatter" (e.g., less of an arcing trajectory for less hold-over/under) then it is the 7mm Rem Mag. (180 gr 300 WM at 2970 fps has 25.3" drop at 400 yds / 140 gr 7mm RM at 3110 fps has 22.4" drop 400 yds)

    If what you are interested in is which one has more downrange energy, then the .300 Win Mag wins. (180 gr 300 WM at 2970 fps has 2024 ft-lbs energy at 400 yds/ 140 gr 7mm RM at 3100 fps has 1717 ft-lbs energy at 400 yds)

    Do some reading (the Fed link above is good) and see for yourself. Go advise here but can't beat your own research.

    For me all other things being equal, the increase in diameter, bullet weight and energy of the .300 WM is worth the 3" drop at 400 yards (which is really inconsequential for hunting). In the end though, either caliber is completely satisfactory for almost anything that walks the earth in North America.

    That said, I'd give the guy (no, insist on them taking it) more than his asking price, helping them out, and giving a fine rifle in a fine caliber a good home and the former owner the pleasure of knowing it will be out in the field where it belongs.

    Shaft...you mean stock?

    If it is a Mossberg, it is most likely a Mossberg 1500 (no longer sold by Mossberg). That was built by Howa...Howa makes some darn fine actions, currently I believe they are making the Weatherby Vanguard series.

    No wonder it shoots well. That would be a good buy at $300.

    Why on earth would you ruin the lines of a classic stock with a thumbhole abomoniation?

    Or, it could be a Mossberg 810. I have one in 7mm Rem Mag and two in 30-06, and it is a very good rifle with adjustable trigger and four opposed locking lugs along with hinged floorplate. This is different from the 800, which has 6 locking lugs similar to the Weatherby Mk V.

    lets compare apples to apples

    Alright if you shoot a 175 gr out of the 7mm mag you would get 2343 fps and 2133 fpe at 400 yards. that is at 2900 out of the barrell. more energy than the 180 at 400 yards.

    reloads from sierra 50th anniver

    Straight out of my reload book and from my 7mm mag. you are comparing 140's to 180's. not fair comparison.

    I compared those since those are more common bullet sizes as far as I knew. I'm sure there are plenty of people using heavier bullets.

    That must be some bullet to come out of the barrel slower than the 180 gr 300 WM but have 300 fps more velocity at 400. What bullet are you looking at?

    Are you sure about your ballistics data????

    I just got out my ballistics software program and plugged in a 7mm Rem Mag 175 grain bullet with muzzle velocity of 2900 fps muzzle velocity. At 400 yards and a BC of .475 (pretty darn high...that's SMK territory), the velocity at 400 yards wasn't anything like you quoted. It was more like 2176 fps and 1839 ft lbs of energy.

    I had to bump up the BC all the way to .600 to get anywhere close to your quoted 2343 fps at 400 yards...I'm not even sure if there is a bullet with that high of a ballistic coefficient.

    What bullet are you quoting? Any idea why the software would show something so radically different from your reloading text?

    seems everyone is assuming that the 7mm your are refering to is a mag. even though you have not specified that.
    if it is a 7mm rem. mag. then it offers a increase in performance over the .308 you were using. if however it is one of the lesser 7mm's then you are not gaining anything.
    .30 cal is a little larger than 7mm being 7.62mm in dia.
    for moose the 300 mag would be a little better if you can live with the added recoil, but a 7mm mag will get it done.
    both will shoot farther than you can see with the naked eye.

    7mm mag

    that is a sierra 175 grain 616 bc. and no the 140 is not the most popular round for the 7mm mag, maybe for the 280 or the 7mm-08. if you use a good ballistic software and pick sierra it will show you the bc. plug it in with the 616 and see what you get. I am using point blank software.

    Hmmm, sorry I think you and I are not talking apples to apples. I was quoting real world hunting loads. My apologies in advance if I've missed the hunting bullet you are referencing.

    The 7mm Sierra 175 gr MatchKing has a BC of .608 but that isn't a hunting bullet. Gotta admit that I can't find a 7mm bullet on the Sierra site that has a BC of .616

    http://www.sierrabullets.com/index.cfm?section=bullets&page=bc&submit=1&stock_num=1975&bullettype=0

    A 7mm Sierra 175 gr GameKing (an actual hunting bullet) has a BC of closer to .533

    http://www.sierrabullets.com/index.cfm?section=bullets&page=bc&submit=1&stock_num=1940&bullettype=0

    With a 2900 fps muzzle velocity, that makes for 400 yard stats of 2249 fps and energy of 1965 ft lbs. Not what you quoted but still impressive. Pretty much the energy equal of the 300 WM. I concede that there is no real world difference between the two.
