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
