Would 4451 work in a .308? I think it may be too slow. Has anyone tried it?

Try imr4166 in your 308. It does anything varget will do and with a copper reducer. It shoots .1 in my 284W

I’ve had good luck with imr4166 also. Probably going to switch my 30/06 over and try it out soon.

4166 works just fine in 30-06, and several other calibers I've tried. It's good stuff. The only problem is, the word is getting out. Lol.

4-shot group 30-06 Hornady 150gr SST and 4166

4-shot group, 243 with 70gr Nosler Varmageddon and 4166

I’ve got 9 lbs of the stuff. I’ve only used it to work up a load in my 416 Taylor imp. So I might as well try it in some different stuff

I'm getting consistent sub-MOA results with 168's on top of IMR-4166 in my .308 Win 20" barrel.

I picked up two pounds of IMR 4451. Gonna try it with the 140 Barnes match burners in my 6.5 CM. I’ve not been having the results I want with this bullet with RL16, even though it’s my go to powder in my creedmoor.

Was very pleased with IMR 4451 with the 140 match burners. Glad they worked out finally cause I picked up 500 of them. Now to build up a supply of 4451

Care to share your load data? I have been working with that same combo, using Starline brass and Fed 210m primers. Best accuracy was found at 41.3gr 4451. I did my load development seating at .020" off the lands (CBTO 2.228"), but after experimenting with the seating depth I got better results at .025" off the lands (CBTO 2.223"). It would appear that these bullets like some jump, so I'm going to do another round of tests with seating depth at .025" off the lands (CBTO 2.223), .030" off the lands (CBTO 2.218"), and .040" off the lands (CBTO 2.208"). We'll see how that shakes out.

Here's what I've got right now, at .025" off the lands. Shot on the left was first shot from a cold bore, then the other 3 were pretty tight.



Cheers,
Brian

As soon as I get home from work I’ll send you my data, I can’t remember it off the top of my head.

That group looks really good. I did try from .005” to .020” jump with these bullets and RL16, but I could never pull it together I believe your on to something with these bullets liking a bit of jump.

Here is my load, 41.6 gr of IMR 4451. CBTO is 2.271” in Peterson SRP brass.

Wow - my 7mm Rem Mag Ruger Number One, with the 26" barrel, showed some terrific velocity with IMR 8133:

Hodgdon's max load for a 150 gr Nosler Partition was a compressed 77 grains of IMR 8133...

Loaded that with Hornady's sleek 150 grain ELD-X bullet and saw just shy of 3,300 fps! One shot in the string was at 3,304 fps. It was a pretty tight spread. I need to work on the accuracy a bit, but I think most of that was me.

More on that later on the Ultimate Reloader YouTube channel.

Sounds like a screamer Guy. I bet that ELD-x load is flat shootin!

Ya, it really is very flat shooting. The 150 grain ELD-X is shown as having a .574 G1 Ballistic Coefficient, and when launched at 3,300 fps... A 200 yard zero results in only about a 5" drop at 300 yards... All I know for sure is that it was absolutely no problem ringing the gong at 100, 200 and 300 yards... And dang! That load thumped the gong!

Regards, Guy

If you can find them, try the 175 ELD with 8133 Guy. I'd bet you'd be quite impressed.
