I bought 2 boxes of 308 and 2 boxes of 7mag 150gr core lokts. Shot my rifles and neither is grouping worth a sh.. These guns have always shot core lokt's really good till now. I got to looking at the shells and seen some of the bullets are not pressed all the way in the casing. Ive never paid attention before to see if they have always been like this. Have any of you seen this before?

They are always like that. Looks like a light perforation just outside the casing around the bullet. I was told that is what makes them "core lokt". May have been misinformed but it sounded reasonable to me.

Think your describing a loose crimp on bullet.

It's possible to get a bad batch. See if remington will make them good. They are very good rounds. Some people trash them but I've killed many deer with them and never had a problem with grouping.

I haven't bought any in forever so my opinion is worthless on the matter.

They all have a crimp. I don't no how to post pics or i would. Its like they wasn't seated all the way and some was. There a little lines going up and down on the bullet. Some are pushed all the way down to the casing and some are sticking out further. No clue but its strang 2 rifles just up and stopped shooting good with them.

When I bought my 7 mag I tried sighting it in with core-lokts and the best I could get it to shoot was about the size of a paper plate at 100 yards. Started handloading 140 accubonds and my grouping problems went away.

Idk where you bought those coreloks from of course but Ive been told the coreloks you buy from Walmart (and other brands of bullets) are not the same quality shells that youll buy from other places. I dont know how true that is, and it dont make a whole lot of sense to me but like I said thats what I was told, may or may not be some truth behind it

My REM 700 7Mag doesn't group well with the corelok. I'm sure others have had better luck...Shooting Hornady whitetail 139 grain now with great grouping at 100yards

Yeah I've been told that WM negotiates with whomever to make item according to WM specs thereby making them cheaper and beating most everyone on price

Ah ok - sounds like something Walmart would do -I just really dont understand why these companies would jeopardize their reputation for that.

I have shot core lokts for years, about 3 years ago my stash ran out of 243's bought 3 boxes. Accuracy tanked. Tanked bad. Switched to federals, no issue. Bought my son a 243, started with core lokts. Accuracy sucked. Went to federal did fine. Sadly I'm done with them once I shoot through my old inventory for my other rifles. Apparently 3 or so years ago something changed. Sadly I will never go back.

Been a long, long time (25 years?) since I've shot any Corelokts in a rifle, but maybe 3 or 4 years ago I bought some crazy expensive Remington Premier Corelokt shotgun slugs....like $23.99/box. They wouldn't shoot worth a turd either, they were really erratic at 100yds. I noticed the slug in some of them would rattle if you shook it.

My Dad and I have shot Core Lokt's for 20 years in our rifles and never had an issue with accuracy. Y'all have began to make me a little bit scared of them lol

Someone recently told me that Remington would not be manufacturing Core Lokt's any longer. Does anyone know if this is true???

I've never shot corke loks. I just buy premium ammo

Well you buy cheap ammo expect cheap things to happen.

When picking up brass at the range, I routinely see misfired core lokts laying around. Don't seem to notice that much with other brands, but have seen it a bunch of times with these.

I used to shoot them and the bullet itself performed well, but quit after noticing this and having a couple misfire myself.

Only round I've ever experienced a misfire with, that' was the first year I ever hunted. All the money we spend on this hobby, an extra 50 cents to a dollar for one of the few things that absolutely has to do its job to accomplish our goal seems pretty petty. I know they've killed piles of a deer, but no one shoots their deer rifle enough to ever see a financial impact from spending an extra $10-$15 on a box of rounds.

These core lokt's was bought at field and stream. Ive shot them all my life with no problems and killed a pile of deer till now. I bought a new tikka the other day and bought hornady sst 165gr and its shooting about 2inch groups witch im not happy with. But idk witch ammo to go with now. Core lokt's have got me worried. Maybe i should just start loading my own.

Only bullet I've used the last 30 yrs is core lokt. Never one complaint by me.

Try some fusions. They last few boxes of core lokt had all kinds of bad tips on them.. slightly deformed or lead overage hanging off one side. The fusions i havent seen one bad tip on.

There us no way Remington would jeprodise it reputation just to make walmart a cheaper box of ammo and still put the Remington name on it. Walmart can sell it cheaper because they buy ammo by the truck load not by the case.
My 30.06 shoots 165gr corlokts very well nether of my 243s shoot well with them. Only misfires I've heard of have been with 30.30s most of that has been due to the slightly harder primers Remington uses

If you want to wring all the accuracy out of a .308 with factory ammo. typically you should shoot 165gr projectiles.

I had a hornady supermonace cartridge misfire a few years ago on a broadside chip shot on what would have been the best buck I've ever killed. Very wise fella told me that if I cared enough about a stupid deer to be upset over losing one that I was crazy to trust some fella that I had never met who was probably working midnights to load my bullets for me. I took that as wise council and started making my own.

I have shot plenty of deer with Core lokts. I still use them in my 30-30. They have always worked, and honestly I am not aware of a better round nose bullet for short range and heavy brush that I could use in a Marlin 336. (safe with round nose in that type of magazine and all).


That being said, I used to shoot them in my Remington auto just out of habit. When I bought my new Browning Xbolt I switched to Hornady Superperformance SST. I am VERY happy with them so far. But I still shoot Core Lokt in the Marlin. is there really a better bullet for a 30-30 lever gun to use in the brush? I can't think of one.

give me a 7-08 and a box core-loc and damn old gerber knife and








i'd throw it all in a river

Word!

Hey now, what did the ol 7mm 08 do to you?!? Ha I shoot that exact same set up and that's all I use...no complaints here! Except Gerber knives are crap lol

Core lokts are all I have ever shot. Never had a problem

Core lokts,,,, really are the deadliest mushrooms in the woods,,,

I've slayed many a deer with them,,, they aren't as refined as the high performance polymere/plastic tipped bullets in all the brands but they are just as deadly,,

accuracy is in the set up of your rifle and in the person shooting it,,, there are times though a bad batch comes through,,

At the rate high performance hunting ammo keeps rising in price I'll most likely go back to Remington core lokts ,,

Last year a buddy and I were sighting in his new .308 with Core Lokts, I think it was 5 of the first 8 shells didn't go boom when we pulled the trigger. He switched to Fusion and never looked back. I know they work for some of you, but I'll pass.

New gun was a POS?

I have to disagree. My .308 Remington 788 doesn't do well with anything heavier than 150 grains.

I'm getting 1/2 inch, 3-shot, 100 yard groups with factory loaded CoreLokts. I've never experienced a mis-fire and the performance has been great on deer and pigs.

Never seen a core lokt misfire.

Me either. Cause I've never bought any

Ol 257 just kinda cuts to the chase, don't he?

It shot everything else we fed it, I would be inclined to believe that the Core Lokts were junk. Maybe just a bad batch?

Had a friend that reloaded some for someone that trouble finding some 7 saum he loaded what the fellow brought to him the coreloc bullets wouldn't group got to looking and the weight of the bullets varried 5-7grains high and low Remington quality has really gone down. He purchased some hornady bullets they were perfect

I have used nothing but core lokts in my browning. Even tried reloading and did not get anything to shoot any better. Inexpensive and I have put a lot of meat in the freezer.

Day-in, day-out, Core-Lokts are a meat and potatoes bullet. Nothing fancy or expensive about them. If I had to pick out a bullet for SHTF hunting and buy a truckload of them, without test-grouping them for a particular rifle, it would be them. Not necessarily super accurate, but they will kill the crap out of deer. And every gas station sells them, it seems.

People I know that shoot rifles as part of their profession say that the batch number on ammo is very important for precision shooting. Ammo manufactured in different batches will perform differently. I'm not sure I shoot well enough to tell the difference, but that is what the pros tell me so I believe them.

Don't know if that is your problem, but it is worth looking into.

Core-Lokts are the worst grouping bullet I've ever shot. I stick to federal and Winchester pretty much now.

I hand load all my hunting ammo. I've only shot now is barns ttsx. I loaded a bunch of core lokts and killed a mess of deer with them but the problem I had with them is they range of different weights and bullet fragments in my meat. You could weigh 50 bullets and be 30 different exact weights.

I can't even bring myself to tell my bad luck core-locks story again. I've shot Core-Lokts for 30+ years but really feel they've gone down in quality assurance/control. I'm purposely replacing them with Hornady and Winchester.

If you have some with ridges exposed where casing meets tip you may have a grouping problem. Had some old ones without ridge and they shot more consistent patterns.

i've had as mush as 1 1/2 " group change from lot to lot . in real time that aint that bad . i dont shot Remington though

can you shoot core locks out of a Matthews ?

Yes, just tape one on the end of your arrow and letter eat!
