30-06 bullet test for 220 grains and 200 grains

Remington loads many Interlocks as "Core Lokts" Dan. Same as the "Accutip" was an SST and I suspect the new tipped Core Lokt is too. Big Green has been loading Hornady bullets as their own brand for quite some time now.
 
Is the 220gr Core Lokt their own design, or does Remington load the 220gr Interlock for that one?

If the bullet jacket has a scalloped edge where it meets the lead tip then it's an original Remington design. I've seen some recent production .30-30 that didn't have the scalloped edge, so the design has been cheapened, but I don't know what that would do to performance.

The 285 gr "Corelokt" in 9.3mm is actually a Hornady Spire Point.

P.S. the scalloped jacket is for the round-nose design, not for the pointed core lokt.

Thank you! The original core lokts seem to have quite a following, but with the revisions, loading other companies bullets etc when someone says "I shoot core lokts" its like...cool, which kind? Sad to hear the original 30-30 170gr has bit the dust. The 180gr round nose in 30-06 eems to have a lot of fans too.

To illustrate what you describe

Pretty surprised to see over .70" expansion AND penetration to 26" + in the video above. That'll do it.

Still lots of nice shank underneath that wide open mushroom, and they go straight.

For one "do everything" cartridge, thats hard to argue with inside that "most of game is taken at this distance" window you mention...looks like it doesn't do a tremendous amount of meat damage on thinner skinned game at those speeds either.

Ballistic Gel is a darn poor medium to compare a game animal to.

Perhaps :)

But it offers a very well controlled medium to test different bullets against each other with as few variables as possible. It provides useful data points.

A few months ago, I received a made-in-1955 Win Model 70 in 300 H&H. I installed a Leupold M8-6X36 scope in the Leupold Dual Dovetail mounts. Is several boxes of Hornady 220 grain round nose bullets - red boxes with metal reinforcements on the corners - does not say "Interlock" on the labels, so I presume they are older than Interlock. Is some 300 H&H brass on the way in the mail - W-W brand - so is likely what will get loaded up - likely will still work adequately for anything that we have in Manitoba bush. First attempts likely will be with RL-22 or RL-25 powder.
 
Strange to read this about Remington. The web and promotional videos state that all components are made and assembled in Arkansas.

Core Lokt will not shoot great in my 30-06 Sako however Interlocks shoot lights out as does all BT ammunition from Hornady. I have a 700 30-06 and it shoots the Core Lokt very well and the Hornady so so.

My 7x57 is very accurate with Remington Core Lokt when I can find it, admittedly most is old stock. The Federal Blue box is barely passable and the Hornady stuff is just good enough.

I find it difficult to believe that any of these shared the same bullet as they advertise the same speed. I know there is more factors at play but an identical projectile travelling at basically the same speed should produce similar results.

It was my understanding that Core Lokt was a flat bullet and Interlocked was a boat tail. From looking at images online it would appear that the older stuff was indeed flat but the new stuff is boat tail.

One promotional video states that the original employees before the take over had innovative ideas that were now implemented in the new ammunition. I assumed this was the new tipped bullet manufactured in house.

I have never used Remington Core Lokt bullets, but is many boxes of flat base Hornady Interlock here, in various diameters - might be time that changed that - or what the bullet buying public wanted.
 
There are also several redesigns of proprietary Remington bullets as well.

Core-Lokt Tipped does look to me an awful lot like an SST though.

As ammo was in short supply, I picked up a couple of boxes of Custom International Hornady for the Sako 30-06. The straight Custom stuff states Interlock BTSP on the side of the box but these did not. I emailed Hornady and got a quick response stating that the Interlock BTSP were used in the International as well. It is the most accurate ammunition I have ever tried but I am now thinking I should pull one and see what is inside.

I also scored some Custom International for the 7x57 that I am excited to try.
 
I agree, makes even fragile bullets look good in comparison with premium but then on game it's a whole different story. Example SST/Ballistic tips look great in gel, nice mushrooms and weight retained. On game they come apart pretty easy.

The ones I've found in moose steak looked good, but then was tending to load all my 30-06 ammo to take it easy on Garands and help them have a long life at the time so...not the most velocity there.

Lots of em are definitely like Nosler BTs with non-beefed up jackets. Kinda caliber/velocity dependent.

Some gel videos are definitely highlighting the fact they come apart though...but if you want 68% weight retention, hey lol. And that's only starting em at 2750 fps or so. Guy has a Tikka with a likely 22 inch barrel but always comments on how they're slower than factory? Lol regardless.

Maybe if someone wants a bullet that holds together better on big game, that might be a clue. Something like a Terminal Ascent or other kind of bonded bullet, or even one of the regular cup and cores that did better than the SST in weight retention/penetration. Unless anyone thinks those wouldn't hold together better on game :)

Would definitely imagine, for example, the 220gr Remington load, which lost less weight, would hold together better in the animal.

Edit to add: it was pretty cool, and maybe much more enlightening, when Federal used to put femur bones and hide on the blocks.

Those examples look great to me. If they could hold up like that on game I'd use them more often. My experience with some of the ballistic tips from a 308 win at modest velocity had the bullet disintegrate. Just lead and Copper pieces all over the place. Killed the animals no problem but was expecting more out of a 165gr BT. In saying that one of my favorite bullets is the 180gr Nosler BT for the 8mm- they have a thick jacket, penetrate well, and hold up even plowing through heavy bone.
 
So the penetration, expansion characteristics of a bullet in gel do not offer indications of its performance vs other bullets?

Would be really interested in examples of that.

No, they don’t. This is the problem. A cup and core bullet in ballistic gel will often retain 100% ish of its weight. In a big game animal I suspect they NEVER retain 100% of their weight. Conversely, a monolithic bullet would have similar retention in both mediums. So how is this a great comparison?

Oh yeah! That ones practically an unbonded "Accubond" lol.

The 180gr Ballistic Tip for 30 cals is pretty stout as well.

I really wouldn't have much fait in something that falls into the 60% weight range in gel unless I wanted Berger like effect...which I don't. Lots of plain soft point cup and cores will do better for cheaper, like a Power Point, etc. Federal Blue box...

Please show me a soft point cup and core retaining 100% of its weight in gel?

have never ever seen this. Again, some examples? You're not showing anything just stating "this happens". Find the idea of 100% weight retention in gel from a soft point one time to be unbelievable really. Let alone "often". I don't mean offense but this seems to be absolutely not grounded in fact.
