That was about all I knew going into the range. I finally got the hang of it. I was using a sand bag to stabilize. I can tell thru the scope I wasnt very steady I had a little sway in my shot. I really want to put the gun in a vice as Im scoping it in.

Good Luck buddy and thanks for the reply and i hope the shoulder goes to feeling better LOL !

DMGUY33 · 07-11-2008, 09:15 PM

I have 40 more rounds comin in on monday, so Ill do some more fine tuning next week. Do you guys clean after every shooting?

roverboy · 07-27-2008, 02:37 PM

I've got one in .30-06 and its a good rifle. Its about 2 years old. Plain jane black stock. I painted the stock Krylon olive green and matte clear coated it. The rifle shoots good though. I've only shot handloads in it. Killed a big doe at 350 yards
with a 150 grain Hornady handload. I'm not crazy about the metal coating. It looks like its been sprayed on. It scratches easily, but seems to be rust resistant. So.......
I matte clear coated it. Looks good,tougher finish,nowit is a ATR, All Terain Rifle.
Thats just my 2 cents worth. Keep Shootin ,David

[quote=DKA1;360847]Anyone had any experience with this rifle?

Ive had a Mossberg .270 in synthetic stock and it may not be the prettiest rifle, not necessarily the smoothest action (Ive got a 95 yr old SMLE that is smoother) but it shoots wonderfully and is very tough and reliable. My MOA's are very decent at 100 yds using Federal or Winchester ammo. Ive not been very impressed with Remington ammo though.
I plan to buy another in wood stock in .308-they look so much classier. I hope Mossberg intoduces a floor plate soon.
If a Remington, Winchester or Savage are not in the budget, dont despair, buy a Mossberg ATR, you wont be sorry.

And the good just got better. For those of you who really like these rifles, and want to make the trigger BETTER than any other rifle you have ever shot, here is a write up that I did that will walk you through it:

http://www.texashuntingforum.com/ubb...e/0#Post489623

The write up is complete with pictures and is very detailed.

I am working on a video that will cover the same material from beginning to end.

If you do the trigger modifications, you can bring the pull down to 3 lbs. or less safely, and reduce the pre-travel to NILL as well. I currently have all 3 of my Mossberg rifles set up so that with your finger on the trigger the gun fires at the first sign of movement of the trigger. I also have the pull down to 2.5-3lbs. of pull. Basic hand tools and about 1 hour is all that it takes me.

LiveToShoot · 08-20-2008, 06:38 AM

Well, I'm digging up this old thread because I have finally put together the cash for a Mossberg ATR 30-06...

...and, I'd appreciate any updates from those who own the ATR about how the rifle is performing for them.

Thanks in advance...

right_to_carry · 08-21-2008, 07:30 PM

It's chambered for .308, and while I was impressed with the recoil handling properties of the thick pad, and the tight groups with the factory 180g Silvertips I was using, it consistently failed to chamber the second round and sometimes the third round from the magazine. The cartridge would jam between the magazine wall and the following case at the neck. Anybody else experience this annoyance?

LiveToShoot · 08-21-2008, 07:55 PM

RTC,

Welcome to G&G Forum...

...and, thanks for the info about your Mossberg ATR 100 in .308, which I'm sorry to read isn't chambering rounds very well for you.

LiveToShoot · 08-21-2008, 09:29 PM

Thanks to everyone for your posts about the Mossberg ATR 100...

right_to_carry · 08-22-2008, 07:11 PM

Update on the feed failures of my ATR (.308) - I did some more experimenting last night, and the problem seems to depend on where in the magazine the cartridges are loaded. If I pushed them back as far as possible, I didn't have any bind up while loading. If they are forward in the mag, they will hang up almost every time. The problem is - the natural inclination is to push them forward while loading, and I don't know if they will stay put if I do remember to slide them back while loading. Still wondering if anyone else has seen this behavior, and whether I should contact Mossberg about it. Thanks for welcoming me to the club LiveToShoot.

I'm guessing that it's because of the 180 gr. bullets. Most .308 shooters only use 150-168 gr. bullets and I'm betting that's what the gun was designed around, but can't say for sure. It might be worth a call to Mossberg to see what they have to say.

right_to_carry · 08-23-2008, 11:06 AM

Interesting! I'll send an email off to Mossberg to see what they have to say about it.

ArkansasHunter · 08-23-2008, 11:18 AM

My Ruger Hawkeye 308 does the same thing with the very exspensive Win. Supremes with the plastic tips.
All other ammo works fine...So I suppose some of what I'll call super ammo is longer than the common ammo.
You guys with Mossberg rifles make sure to try 150gr. Remington core-lokt's there still excellent deer cartridges and shoot sub moa in my gun and maybe they will in yours...A.H

Well I have a 30-06 and after 60 rounds haven't had that happen once.

That is exactly what I've been shooting and it has had excellent results so far.

The ATR 100 has an adjustable trigger , the screw heads were ground off at the factory and the screws were put on with loc-tite , there is a simple way to adjust these triggers without any grinding or spring replacement , in fact, they will adjust down to a 2 1/2 to 3 pound trigger quite beautifully. I have mine on 3 pounds with no creep or over travel . The first thing is to loosen the lock nuts on the adustment screws and then the screws themselves . To do this you remove the trigger from the action , then you take a cigarette lighter and heat the screws , they dont have to be very hot ,the heat will cause the loc-tite to break free, with a 1/4 inch wrench you loosen the lock nut on the front screw , dont take it all the way off , then you heat it again and then using a pair of needle nose vice grips you can loosen the adjustment screw , this is the weight of pull screw , back it out only slightely as it is very sensitive , little at a time till the weight of pull is where you want it , then you tighen the lock screw back down . Next you heat the overtravel/sear engagement screw , thats the one at the back of the trigger , you can see in the little window of the trigger houseing the sear engagement . Adjust this screw inward till there is no creep and no more .

You DO NOT want to set the sear engagement to where it is DANGEROUS. Now tighten the lock nut. Now that you have your trigger adjusted , you need to take the trigger and sear out of the houseing and polish them to a mirror finish , I first use 400 grit sand paper then 600 , then 1500 grit . Then you coat these with a good gun grease to make them even more smooth . Reasemble and trigger job complete ... If you really want to do what I did , I removed the adjustment screws and filed the ends off where Mossberg ground the heads off and took my hacksaw and cut some screw driver slots in them , now i have adjustment screws that work.. Kawabuggy has some great pics on taking the trigger apart and reassembling , I am gonna post the link to his pic's and I hope he don't mind that i do that http://www.texashuntingforum.com/ubb...e/0#Post489623 Good Luck ,,, dlg574

bigtrev · 08-27-2008, 06:22 PM

Thanks for all the great info guys, I have recently purchased the ATR-100 in 30-06, matt black barrel and black synthetic stock for hunting Sambar deer here in Aust. Test firing and zeroing in the 3-9 x 40 scope (I already had ) resulted in MOA group at 2" high at 100 yards. I am very pleased with the performance and feel of this rifle and as it will get knocked around I am sure in the scrub then the integrated trigger guard etc won't matter. The first time I picked up the rifle and put it to my shoulder it felt good with light weight and good pointability. Recoil is ok but I won't be firing multiple rounds on hunts. One shot per hunt is all we need eh? I'm using 180 gr Winchester Super X CXP2. May have to go to CXP3 but will see how we go with shoulder shot on deer. Matt black barrel is scratched already but I am going to whack on some camo tape next and put some on scope as well.

Mike82 · 09-09-2008, 05:28 PM

I gots a neat lil story for ya.
I visited the local pawn shop today, owner told me he had an interesting deal for me....brand new Mossberg 100ATR in .30-06cal.....i thought to myself thinking, a 'mossberg rifle?!?' hmm, wonder how this'll play out....well, i'm glad i read the reviews here....the one he has is a laminated wood stock, doesnt have any scope mounts or rings, but it is tapped, so that'll save me time of removing old pieces to add leupold bases/rings....he told me he didn't know value of it, he got it on accident in an order of mossberg 4x4's....so me not knowing what to offer, i thought"well, mossberg is a good quality firearms company, and a good .30-06 usually goes for 300-400bucks" so i offered him $200, and he agreed....he's gonna clean it up a lil bit cuz there was some fuzzy stuff in barrel and i didnt have time to wait....gonna go tomorrow morning and pick it up....he did say he would absorb the tax....now, since i didn't ask for him to absorb tax or anything, he just offered out of the blue....i'm wondering if the gun is really worth all that....it is brand new, never been registered, or shot, except maybe test fired at factory; does that sound good anybody? the rifling looks smooth and straight from muzzle to chamber, so not like it's a "gray market" gun, or an "oops gun"....tell me what'ya think.

unclejer · 09-11-2008, 02:46 PM

I bought one a few years back in.270 great rifle right out of the box. If you are going to use for coyotes use 150 grain core locked and hit them in the boiler room not the shoulder bullet is more fur friendly does not expand just makes a dime size hole going in and most of the time a nickle or quarter size on the way out. If you hit heavy bone let me say you will need a sponge and shovel to clean up the mess. With this method so far farthest runner 3 inches it fell forward when hit. Likes cheapest ammo 130 or 150 no jams except with wolf 150 grain
rem and win in white box at Wally world works best

Mike82 · 09-12-2008, 01:20 AM

well, i found the first defect....the rifling is smooth as stated....but it's the opposite of sharp, it looks like almost smooth-bore, rifling is maybe .001" taller than valleys....is that how it's suppose to be for these rifles? or is it infact an 'oops' rifle....only other rifling i've seen like this were in some US made semi-auto pistols, mostly small cal like .25's.

and if it IS an oops gun, how much is a new barrel? or should i just return and see if he'll sell me a 4x4 for a discounted price?
