    First time I have ever tried reloading them I can't find an accurate load for them
    6-06 Ackley caliber
    tried H4831 51 grs to 54 grs gave up
    now working with VV N165 workied up tp 53.0 grains
    but nothing real good yet.
    any sugestions as to what powder.
    Also OAL is 3.340 max magizine length.

    Well, you are using one of the cheapest bullets on the market so you shouldn't expect great accuracy, but my guess is that you are probably just pushing them a little too fast for what the bullet was designed for. My experience with core lokt has been that they either work well or they don't. And when they don't they really really don't.

    I would switch to another bullet and see what happens. Coreloks are not known to be the most accurate. Although I have a 25-06 that loves them. You used to pick them up real cheap, but they discontinued them.

    It is very interesting how that works sometimes. I shoot a lot of 243 using that same Remington bullet you are, two different rifles, one works well, the other not so well, all factors being equal. I built a 7-08 about six years ago, tried many bullets, stayed in the mid range of bullet weights, 130-154 grain range. The cheap and plentiful 140 grain Remington cor-lokts proved to be the equal of any other bullet I tried. The Remington bullet has always been a good performer on game and this combination has proven to be the most consistantly accurate of all I tried. I find the 130 gr. C-L in 270 to work well also.

    Slooow burning powders of course, are the way to go, especially in over-bore rounds like your 6mm-06 Ackley and the 6mm-284.
    Rel-22 is a great powder, and if you add another bullet for comparison, you may find a combination that works. It's rare that a Sierra bullet won't group well, and that's what I recommend trying, along with your Core-Lokt bullets.
    You'll also find that some rifles just will not work with some brands of bullets, so you try something else. That's half the fun of reloading.

    I've seen a lot of "lot# to lot#" variation with the CoreLokts.
    Remember, that Remington makes "millions" of these things. Often, the bulk bullets we reloaders get from Remington are the "culls" or "blems" such that that Hornady often dumps at cut rate prices, rather than passing off as "first quality" products like Remington sometimes does.

    I've seen some .30/30 150gr CoreLokt Round-Noses that due to a mis-function of the core ejector pin were "hollow pointed". But not all in a single box..... Occasionally, you'll even get a "boo-boo" that got passed the q.c. inspector. ie: no jacket, or jacket with no core......

    Sometimes, you'll have a lead smear running done the ogive from excessive lead extruding from the jacket.....

    I've currently got a batch of .308 180gr Corlokts that are the most accurate bullet for my .30/06 and .300Rum.
    I've also got a box of .257" 100gr that won't group inside 3" from my .257Roberts (x2) and .257wby. Definitely not a single rifle "disliking" the bullets. But I've had some other boxes that were easily sub-moa from all three rifles......

    You can "weigh" individual bullets and sometimes by seperating them, you can get the "flyers" out of the "good" bullets. Sometimes, not.

    You just did a very good job of explaining why I will never buy remington bullets any more. why gambel if you are getting good bullets or not

    fwiw; I've gotten "bad" Hornady's and Noslers too.

    I got some 150gr solid-base Nosler Flat Nose that wouldn't expand on anything softer than mild steel plate. (early -1980's).

    Several lot's of Hornady's that wouldn't shoot under 12" at 100yds (1993, 117gr .257" BoatTail Soft point's. Would hit the target side-ways). Also, some bad 140gr .284" SST's, and some bad .338" 200gr Spt.

    Not to mention the Nosler Ballistic Tips that "blow up" on contact with anything more substatial than a paper target.......

    I won't trust a $$$$ out of town hunt to Hornady's any more. Been burned more than once.......Or a plastic tip bullet either.....Bonded or not.....

    And I shoot a load/lot# to as far as I intend to use them before taking them on a $$$$ hunt, too.

    Core-lokts are great hunting bullets, they are not BR bullets.

    How can they be good hunting bullets and not be accurate?
  11. Ridgerunner665

    Good hunting bullet = smooth feeding, reliable expansion, at least 2 MOA accuracy.

    Good benchrest bullet = sub MOA accuracy...not much else matters.
  12. OKIE2

    that means you just missed your target 6 inches at 300 yards

    Not necessarily...the heart, lung, liver "kill zone" on even a deer is about that size.

    I get where you're going...I prefer accuracy when hunting too (thats why I like Nosler Ballistic Tips)...but some guns, regardless of bullets, won't shoot even 1 MOA.

    And some hunters are willing to accept 2 MOA as acceptable...for years Remington had a 1.5 MOA guarantee on all the 700 bolt actions.

    The point is...benchrest accuracy is in a class by itself, not measured in inches...but tenths of an inch.

    "How can they be good hunting bullets and not be accurate? "

    Well, saying Core-Lokts aren't target bullets is far removed from saying they are "inaccurate" so I don't know where you get that; they are probably the most successfully used game bullets that have ever been made. Fact is, very few game rifles and/or hunters shoot better than 2 moa so being a hunter doesn't mean everyone needs to be a 300 yard game sniper. Only an excited youing hunting newbie will shoot at game he's not certain he can hit properly and the accuracy of his rig off a bench can't change his inability to shoot well in the field. Mature folk know their limits and will get closer if they have the hunting skill ... or they won't shoot at all!

    Given that game departments say some 90% of all deer are shot well inside 100 yards and only a tiny fraction are shot out to even 200 yards maybe it's not necessary for most of us that we hunt with big bore BR rifles and loads producing 1/4" or smaller groups to shoot deer very dead.

    Core-Lokts are like 30-30s for killing deer.
    More deer killed w/ 30-30s than next couple of calibers together.

    More deer killed w/ core-lokts than next 6 or 8 bullets put together.
