300 win mag

[lamar_hunter]

Hey guys i have a winchester model 70 300 win mag. I went to make sure she was sighted in the other day and it just doesnt seem to be putting out the groups. im shooting remington core-lokt 180 grain bullets. Yes the gun is clean. Does anybody have any advice on what ammo would be a good try or any other reccomendations? thanks.

with factory ammo you just gotta find one that works. it can get expensive if you have a picky gun. try some of those federal fusions, they load barnes bullts and ive had good luck in my dads rifle with them. of course i dont shoot factory ammo any more, reloading is the only way to go if you want real accuracy

With my remmy 700bdl, I always had great accuracy with 180gr core lokts.  But with my Ruger 77 all weather in 300winny, it didn't shoot core lokts very well.  It did shoot Winchester spupremes loaded with the Winchester version of the Barnes X bullet that is no longer made, can't remember the name, shot those real well though.  Probably since '94 I have been running nothing but handloads through both those guns as well as my 25-06 all shooting swift scirocco's.  My 325wsm just loves the Winchester supremes loaded with the Accubonds.  If reloading powders would allow me to duplicate factory ballistics with my WSM, I would be handloading for it as well.

If your sticking with factory ammo, you'll just have to buy a couple different boxes and find which one your rifle likes to eat best.  Try the remington safari grades for your 300 loaded with the swift scirocco.

is this a new problem? as in...did you shoot this gun fine last year? different ammo? what kind of groups are you shooting wit the core-lokts?

[Thehowler]

I own the same gun and I have allways shot Federal premium 180 grain nosler partitions with great success!

I'd try Winchester factory ammo with power point bullets.  They are not very expensive and the power point bullets hold together ok..........at least as well as cor-lokts.

Might give the Federal Classic ammo a try. I have had the best luck with them when I have a need for factory ammo. Its the stuff in the blue box.

My wifes 6.5x55 mauser in the short barrelled carbine form absolutely devours those bullets.  Can't believe she can shoot the groups she does with that gun and somewhat crappy old military trigger.  They shoot so good out of her gun that the reloading die I bought for the gun sits unopened, just no reason to reload for it.

 :)Are the mounts and rings tight? I also like Federal Blue box cheap ammo.

i have a winchester model 70 with a pre 64 action and it's chamber in .270 and i've found the best to shoot for it are the winchester supreme....I also have shot the fusion bullets and they work out pretty good as well...good luck

I was out shooting mine (savage model 110) with the same 180 core locks and my groups were pitiful at best- about 2 inches to either side and up. The elevation stayed between 1 and 2 inches high. This was at 116yds.I didn't adjust my scope at all yet because I got the goods to reload and I want the brass. I am new to reloading and have yet to find the load for the gun.

I have a Ruger 77 all weather and have found the 180gr Winchester ballistic silver tips to shoot best out of my gun.

[carpsniperg2]

like the guys have said try diffrent ammo with factory loads thats what it takes to find a great shooting ammo in your gun lots of guns shoot good with the rems but some hate them and won't shoot worth $hit also check your basics if the gun is just starting to do this your bases rings etc if you just started shooting it definanly might be those loads in that gun

[lamar_hunter]

well before deer season all i could get my hands on was some grey box winchester and it shot alot better than the core lokt bullets.

[elk311]

It's unfortunately true, some guns just like certain types/brands/weights of ammo. My Mauser only likes 180 grain bullets and that's all that it will group. Tight groups! but try another weight of bullet and it turns into a shotgun.

Just have to find that sweet round. Unfortunately now-adays that translates directly into $$$. Of course my $198 rifle would only settle for Federal Premium rounds, right? So much for saving a few bucks on a "cheap" '06.  I love it though once I found the right round.

Good luck !

federal fusion, shoot it out of my Tikka 300wsm and 270.

[NORRISKI]

Try Hornady 165 grain Interbonds. My 300Win  loves them.

[Sawbuck]

I've always shot 180 grain core lokts with my 300 win mag with pretty good results, but no more. I went from an inch and a half group at 200 yards to about an eight inch pattern. I thought it was me or my gun, tried everything, couldn't get a better group. I ended up shooting a few rounds from a box that I had bought a couple years ago, and they shot great. I figured remington must be doing something different cause any of the newer boxes I've tried are not accurate at all. I tried federal premium nosler partitions and Fusion. The fusion worked great, I have been consistently getting 1 1/4" three shot groups at 200 yards. Also very happy with their performance in the field.

Did you pull the action off the stock? If so you probably didn't tighten up the bolts to the same torque as before

[lamar_hunter]

no i havent taken it apart

[Elk-aholic]

I would start with buying some good bore solvent like Montana Extreme something that has a little ammonia in it to clear out the copper deposits, even when you clean the rifle with bore cleaner many brands only clean powder residue and leave the copper in. Try to clean it again with Butches or Montana copper solvent swab the barrel out and wait about 15min than keep running patches down until they come back totally white. I would start with a good cleaning before I tore into the scope or stock. Ive looked down barrels before that appeared totally clean but after using Montana extreme I was amazed at how much crap came out of my Sako after I just ran Hoppes solvent down the tube the Montana picked up all the copper that Hoppes left behind. The good brands cost a little more but I think you save a lot of time with cleaning in the long run, Butch's and Montana Extreme are well worth the extra money.

[Chopaka81]

Yea - what Elk-aholic said.

I remember running into a similar problem with a tried and true M700 in 270. I used Sweets 7.62 to remove the copper fouling.

On a Wby Vanguard I was even more embarrassed to find that I had a couple screws loose on the scope mounts. Think I went thru 3 boxes of handlods before finding my error.   

Hopefully you found some of the grey box Winchester ammo.

Good Luck,
