Mossberg 100 ATR .243 Review
Sean @ Everything Hunting has written a review on the Mossberg 100 ATR:
The Mossberg 100 ATR is one of the least expensive guns on the market. Coming with a price tag of about $298. What can you expect from the gun? I found the gun pretty accurate and light to carry at only 7 lbs. I bought the Realtree camo pattern with matte black barrel. I used the gun exclusively during the 2006 hunting season.
I have shot 3 deer (all head shots) with instant results at ranges of 15-85 yards. At the firing range I maintained accuracy consistent with a 3 1/2 inch bullseye at 100 yards. These results were sandbag gun rest only without a vise. I find the results to be consistent with my abilities. I feel that I may be able to bring the group closer with a better scope.

Have you done a blog that I could compare this rifle with a Mossberg Marlin .270?, or could you do one?
You aint got a dang clue what you’re talking about!!!!! you don’t shoot a deer in the head!!!!
Dude, Hank is right. What kind of retard is writing this crap. All head shots? Is that really something to brag about?
Shooting deer in the head gives you the minimum amount of meat damage. And therefore shooting deer in the head actually makes a lot of sense……unless you like picking out bullet fragments out of your meat.
Headshots are the very best!
As Jon said no meat damage.
And I have yet to have one run off and die somewhere else.
And as to bragging, head shots require a smaller target hit area.
I just ordered the Mossberg 100 ATR in .308 caliber. I am very excited about trying it out. I will be hunting coyote and hogs in the off seasons and then come fall I will test in on antelope and deer. I never shoot them in the head. I always go for the shouder / lung area.
Im not exactly an authority on deer hunting, but if you shoot them in the head, you have less meat damage. shooting them in the neck/lungs/heart will result in a better trophy head, if thats you want.
tom, shooting in the head is a bad idea. The skull is a very small area and hard to hit. Also, the skull is hard and bullets have been known to be deflected and/or travel along its contours.
3 1/2″ Group is terrible I just finished packing up my Mossberg 100 ATR .243 to ship it back for service this rifle is a piece of crap. I also have a ATR 100 in 30-06 Caliber that shoots a 1/2″ to 1″ group so apparently something is wrong with the .243.
I have the 100 ATR in 270 win. I have been able to hold 1-1.5 MOA at 850 yards with this rifle. I have formal training in well you could say “long distance target practice” from uncle sam, but there is no reason why any Lay-person can not accomplish the same. It’s a cheap gun, that is low price not quality, so spend some money on a good scope and it will do you great. As for the moron that shoots deer in the head, thats not the best idea you may have been lucky so far but honestly the proper way is a heart shot and there will be little or no meat damage people were not talking about taking it down with 00 buck seriously.
I have a little bit of Uncle Sam’s training Myself. I sent this .243 back to Mossberg twice, once for a broken ejector and the other time for chambering prolems they sent me a new gun. I put a decent scope on it and it shoots a 3/4″ Group at a Hundred. I haven’t had a chance to get to our clubs 500 Yard Range yet I’ll let y’all know when I do.
I haven’t bought, shot, or even held one of these rifles yet, but I’m considering it. I’ve read your posts. Regardless of whether a deer gets shot in the head or not, does the gun perform well enough to place THAT shot? I’m not a member of the uncle sam’s club, but I am 10 yr. law enforcement and a very avid shooter and reloader. I’ve found that even some of the worst rifles rated, such as the NEF’s, did in fact shoot poorly. However with some time and DEFINATELY good optics, a pet load was developed and these rifles have out-shot (5 shots in a dime at 200yrds.) some of the better shooters I know with quality name brand rifles. They still remain to be some of my favorite rifles today. My only concern is that the rifle is good enough to work with. Is the rifle accuracy workable? I don’t care about ethical or non-ethical shots placed on deer. So, if anyone has anything to add that may help me make my mind up about buying this particular rifle, please, do tell.
I am picking one of these up Thursday.
For the price, you won’t find a better deal, on a starter rifle. The Remington 770 in 30-06 felt like crap. The bolt was getting stuck on the safety for christ’s sake.
It is lightweight, comfortable, and low priced.
IMHO, I love it.
Buying it in 30-06. Ill let you all know when I bag my first buck.
By the way, just FYI, it will be a lung shot. LOL
I just got back from Iraq (Nov. 4, ‘09) in time for gun season here in Texas. On a whim, I bought one of these rifles from Academy Sports and Outdoors for my 14yoa son. I was tired of him banging around my “good” rifles with nice wood stocks, and 14 is past the age of having his “own” deer rifle in our family. So…it was on sale. $299. That included a scope, the rings and the rifle. For the price, it seemed like a good deal. The action was smooth, the scope had a clear sight picture, the new trigger is great, and a synthetic stock and matte finish on the barrel make it hard for even the most determined 14yoa slack jawed goober to mess up. I got the .270 because I wanted my boy to have a rifle that he can use as long as he hunts. He’s a man sized boy, so recoil isn’t an issue. I got the rifle bore sited at the store. The guys were very helpful. I’ve never had any problems with customer service at Academy. We each took a couple of shots from 50yds at deer camp and had 1.5 inch groups with cheap Walmart ammo. Eventually we’ll get some hand loads from my Dad and we’ll put some good rings on it. Out of the box is just fine for this first season. Thanks Mossberg and Academy. This is already a good welcome back for me and the youngun…He’s really not that slack jawed…just a goober!
I have been shooting one of these for 3 years now and it was one of the first ones out with black synthetic stock in 30-06. Mine would not group well when I first got it due to stringing when the barrel heated up. The first and second shot were fine but after that it wouldn’t shoot in your hat. I sent the barrel and action to CryoPro ($40 plus shiping) to have it stress relieved and it was an amazing improvement. Now it shoots 3/4″ groups day in and day out with anything I put through it. I have a knock off Leupold mark 4 M1 scope from china and it was the best $60 I ever spent. I have owned the real mark 4 and this scope is just as accurate and although the optics are not nearly as good it has accounted for over a dozen 1 shot kills on Antelope, Deer and Elk out to 300 yards. My trigger was terrible when I got it (7 lbs) but I understand that the newer ones are better. The trigger was actually fine but a lawyer must have adjusted mine at the factory. I took off the lock nuts on the headless trigger adjusting screws and heated up the screws to release the locktite and replaced them with 10-32 allen set screw the same length. I was able to get the trigger down to a safe 2 1/2 pounds and no more creep! I have under $400 in the whole rig and it out shoots my custom $2000 700 remington in 7mm STW! I bought it as a beater truck gun that I didn’t have to worry about but now I wouldn’t trade it for anything! As for the guy head shooting deer I have to say I have done it too. I am a meat hunter and when you know your gun and your range (under 100 yards)and have a steady shooting position I believe it is OK too. I prefer a high neck shot when the ranges are short but it depends on the shot angle. Anything past 150 yards and you had better be shooting for the boiler room of the heart and lungs. I am mainly a muzzle loading squirrel hunter so head shots are a must and when a deer makes a big mistake and comes too close the only shot I can rely on with my .32 is a head shot. I have never had to track a deer yet…they just lay down and don’t get up:-)
I personally love my mossberg 100 atr 30-06. It is very accurate and for the price you can’t beat it.
I’m very interested in picking up one of these guns as well. Im not sure which caliber I want to get, I’d like to get something smaller because I already have a .30-06 I hand load for and I would like to find something smaller that I could load lighter for varmints or load heavier for deer if I choose to. One of the things that interested me in this rifle is the price but also I believe I saw somewhere that they have a Winchester action on them and I love my Model 70. Anyone know anything about this or have good insight to provide on the rifle? Thanks.
