Took the 308 out with imr4007sc

[nastynatesfish]

Well finally got out with my loads or imr4007sc.
I started out at 47gr and loaded: 48, 48.2, 48.5, 48.8 and 49.1 all at 2.790" all the 48-49.1 were 3 shot groups
The 47 was a load I tried but the wind got me. The 5 shot clustered about 5/8" all together.
The 48gr load

The 48.5gr load

The 48.2 opened about 3/4"
The 48.8 did the same and the 49.1 which flattened primer and blew one was about 1"
Here's the brass

It's 49.1 on the left and 48 on the right. The two sets with the mouth up are the ones that shot the pics, the 48.5 and the 48gr
I'm gonna charge a few up at the 48.5 and move in and out .005 and see how they do. I'll check with my crony next time out.
Again this is through a savage f/tr 308 30" barrel. Shot off a sled unweighted. Was about 34 degrees and at 4200' elevation

What bullet? or did I just not see where you wrote it...

 

[nastynatesfish]

175 nosler custom comp. I still have about 150 left then I need to tune it again for my 175 smk, I've got about 700 of them

Nasty,
What distance is that? Thx

 

[nastynatesfish]

Just at 100 just trying to work up. I sighted with some 155s and started for groups. The 47gr load shot well and could probably got better out of it but I wanted to try more velocity

 

[stinnett1981]

Is this a new rifle? Is this the first load you tried. If so, you should give Varget a try. It works great in my .308. It likes a full case.

 

[nastynatesfish]

I got it used from a forum member. I have. Argent to use but don't want to since its semi rare these days lol. I save it for my 7-08. I have 8lbs of 4007 and it seems to be working well. I have nothing else to shoot it in so figured since I don't see it as a regular powder for 308 I'd give it a whirl. The have it in stock at 3rdgss.com now. Kinda thinkin of buying another jug

I really like 4007. It gives good accuracy in my 7mm-08 with a wide assortment of bullet weights. If there's any downfall, it does seem to burn somewhat dirty, but then again, I don't push the velocity & pressures up very high (maybe the reason). Have you tried it in your's yet? If not, you might be suprised. 1st pic is a 3 shot group with 130 gn. SMKs. 2nd pic is a 5 shot group with 140 gn. Berger VLDs (backer was in poor shape on this one).

 

[nastynatesfish]

That's some fine shooting and good to know about the smks I have about 500 of them. Mine just shoots too good with varget and runs3028 averaged velocity
This is 5 with nosler hunting bullets

 

[mattt]

Which is s the group the one on the left or right?

 

[nastynatesfish]

If your asking of my last it's th whole thing. I dropped the last one cause I was looking at my group instead of trying to line up same shot. I always do that, blow a good because I start looking at it. Mine is a solid .25 shooter I was suprised and blew it lol

 

[eric32]

what velocity are you getting with the 4007SSC ?

 

[nastynatesfish]

I haven't cronyed them yet. Last weekend was crappy weather wise. Hopefully this weekend I can get out and shoot them over it. I'll post up when I get it.
