Remington Core lokt powder?


November 20, 2007, 09:58 PM
Hello everybody,
I was wandering if anyone knows what powder remington uses in their .30-06 165gr core lokts. I have been trying to work up a good load in my friends savage 110 for a couple of season now and have gotten only decent grouping, nothing great. I've tried 4350, 4895, 414, 380, anyway many different types. Well this year we haven't had time to play with new rounds so I told him to get some core lokts and group them for a hunt next week. Well, they shot great and Its like a pricipal thing. I just want to know:banghead:

Thanks Vince

Have you pulled one apart yet and looked? It should at least give you a starting point.

I won't go into too much detail here, but a lot of times the good grouping has less to do with the powder and more to do with how much of it is in the case.

I start by using 1 grain or 0.5 grain increments about the middle of the load books specs on whatever powder I use. Varget has provided excellent results in my 223 and I've read a lot of praise about it here in THR across a wide range of calibers. I found that in only a grain or two difference in my loadings I went from 2-3" groups down to less than 1" groups at 100 yards.

One last thing, all those great factory rounds always seem to have crimps on them. I think this does a whole lot of providing good pressure consistency for the initial ignition process of the powder.

you can't even to begin to identify a powder by pulling a round apart as it could still look different than a cannister grade powder.

I've tried powders, seating depth, different cases, primer combinations, etc. I had alot of remington 150gr core lokts and used them as fouling rounds, his gun didn't like them either, but never the 165's. I told him to pick up the 165's just because his gun didn't like the 150's and I've never tried them. I was just looking around the forum last night and thought I'd ask. I didn't break a bullet apart or anything, It started working on me AGAIN and thought I'd ask.

Thanks Vince

For bullets in the 165 to 168 grain range in the 30/06, I've found Varget to be an excellent powder.

In a wide variety of cartridges I've found that the particular powder used makes a huge difference. I usually start loads about the lower third of the published range and, depending on case size, increase the load. In a 30/06 size case, I would increase the load in 0.5 to 1 grain incremenets. As the load is increase, the groups will generally get smaller in size and then will get larger again. The load I choose will be where the groups are smallest. This generally ends up being at least 2/3 of the way to the maximum published load.

As for crimping helping accuracy; sometimes it does and sometimes it doesn't.

if it makes you feel better- I haven't gotten core-lockts to do anything worth while past 100-150 yards in 7mm-08 and 270 win either. I have had great luck with hornady. . .couple dollars more a box- but they cooked up much easier for me.

PS forgot to add- in the 270 i had better results with a medium crimp on the core-lockts.

my best results with the 06 has been with IMR 4064.
aint this fun??????

Look at this website if you haven't already. I noticed IMR 4064, IMR 4007, and VARGET also listed for 168gr bullets for the 30-06.

Keep in mind that the Reloader 19, Vit N140, and W 760 are listed for this application elsewhere.

I use 45gr of Varget for 140gr Corelokt in my 7mm-08 in my Remington 700 LVSF. Shoots inside 1" @100 consistently. Gives a 2" MOA at 200. 3005 fps muzzle velocity.

birdbustr- i'll have to try that- for me they are good at 100, buckshot past that.

thanks for the advice

I switched this year to remington bullets:the only reason was hornady prices are going threw the roof
The qbove was IMR 4350 and winchester primer 100 yards from the bench
My rifle is a handi 30-06 single shot I think my OAL is 3.310 I would have to look but it is off the top of my head

you can't even to begin to identify a powder by pulling a round apart as it could still look different than a cannister grade powder.

The hell you can't, at least you'll know if it stick, ball or flake. Sheesh, I said "its a start", not an end. At least this way the OP could shop for the same "type" of powder and work from there. All things being equal, at least he'd eliminate 66% of the offerings by simply narrowing it down to a specific type of powder. Sorry to rant, but some people don't interpret data provided properly.

IMR4350 provided similar results to those illustrated by lonewolf. 0.6" at 100 yards. I used it in a 300WSM with Nosler 165 Accubonds.

I wouldn't fret too much trying to make a certain combination work if you have found other combinations that do. A few more dollars per box for hunting purposes it well worth it to me.
