7mm-08 Nosler brass and load questions

[elkeater2]

I finally decided to go all in and bought some Nosler brass. It's almost too pretty to shoot I've worked on this rifle for a long time, but still it has been my most challenging. I used W-W brass, then downsized Remington .308 brass. I've neck turned and uniformed. This is an Encore and the barrel just doesn't shoot as well as my others. The tuning I've done has shrunk groups but it still does some of that "two touching, one out".
So I got the Nosler brass, and decided to start fresh with some Sierra 120 gr. Prohunters and WLR primers. I have several powders, decided to start with IMR 4350 and Varget first. Loaded to 2.800 COL.

I started with the IMR 4350 low and slow, no problems. Increased loads up to what most sites, books and data shows as approaching max. Here is the actual question - in comparison with all that load data out there, velocity was 150-200 fps slower. I stopped at 48.3 gr. and 2914 fps. That's pretty slow. There are many loads that go over 3,000 fps.

I tried Varget and got just over 2900 as well with 45.25 grains, then stopped. Varget is closer to producing at the expected levels than IMR4350 is. Interesting that Nosler data shows use of IMR4350 (most accurate!) w/120 gr. bullets - yet Hodgdon doesn't list it with 120's. Primers look good.
This is a 24" barrel with a relatively long throat. It doesn't copper up badly, and I just cleaned it to the max. I haven't shot for groups yet, as I would like to at least get 3000fps+ out of it with these bullets.
This is my first experience with slowness, so new territory for me.
Am I dealing with lot-to-lot powder variations? Does Nosler brass commonly have greater or less overall capacity vs. WW or Remmy brass? I will load and shoot some more today, but taking my time.

I think part of your problem is barrel length. In looking at their online reloading manual they list a 26 inche barrel and your rifle has 24". Because of that, you could expect to loose about 50 fps.

Some rifles just shoot lower velocities. If the chamber is on the larger size of SAAMI standards, it will require more powder to generate the velocity you're seeking. Frankly, I wouldn't be overly concerned if the accuracy is there. The difference in energy between a projectile at 2914 fps and one at 3000 fps is really insignificant at distances under 400 yards. However, 2900 + us about what I would expect with the powders and charges you're using. Try increasing your charge in 0.5 grain increments. QL projects a maximum charge of 52.3 grains of IMR4350 for a velocity of slightly over 3100 fps with a 24 inch barrel. Varget at 47.3 grains is projected to deliver just under 3100 fps.

Thanks for the quick replies! I'm well aware of the barrel length effect on velocity, and that is reflected more with IMR 4350 than Varget. Those QL numbers are more in line with what I expected. Many people "eyeball" for pressure in different ways, yet for this rifle it seems the soot contamination on the neck is an indicator. With other load combos, as I approach that theoretical 'max' the soot travels up towards the mouth and nearly disappears. I've still got plenty of soot with the loads I stopped at. Been ages since I asked for a QL run, but I'd like to see it with 120 Sierra PH and 139 Hornady SP's; 24" barrel 1:9.5 twist; WLR primers; 2.800 COL; Nosler brass; max loads for multiple powders; load sets for Varget and IMR 4350.
Hope that's not too much to ask!

I get good velocity and accuracy using RL17 in my one 7-08 . if you have it , give it a try too .

 

[DrMike]

Soot is usually an indication of low pressure so you don't get complete seal with the brass against the chamber wall.

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 59300 psi, or 408 MPa
or a maximum loading ratio or filling of 110 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
USE ONLY FOR COMPARISON !

2 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

Thanks, DrMike, I'm sure you had better things to do this day! Hopefully, others will benefit from the data, too. A couple interesting things : the data for IMR 4350 and Varget are almost an exact match for my results yesterday. That adds to the confidence level. The 139 Hornady data also matches my experience closely. The multiple-powder 'Near Max' for both bullets does not include Varget or IMR 4350, but you gave me those in detail already. I will load some more today. I weighed several pieces of the Nosler brass, along with W-W and downsized Rem .308 Win -- the Remington's are almost exactly the same, and the Winchesters about 6 gr. average lighter. Hope all is well with you and your family, and Thanksgiving is a special time.

I've been spending the day dealing with insurance after a newbie to the north slammed into my pickup.

Thank you for the Thanksgiving wishes. It was a very good Thanksgiving for us. Canadians observe Thanksgiving on the second Monday in October. However, I will be communicating with family in the States tomorrow. Have a blessed day of remembering God's goodness to you and yours and to the nation.

I have found, out of my 7mm/08, that it's a spoiled little Brat, as to what it wants as powder for a particular bullets weight. Bullet brands, per weight, don't seem to matter all that much though.. Hmmmm..

120's have to have RL-15
140's will not group w/o Varget
150's demand 4064

I'm shooting a 22" tube, and have never got published velocities, probably never will, but still get 'more' than enough to take game way past where I should be trying to take a shot.

I m had good luck with 45.5 grains of Varget and 120 s in a couple different 7-08 s. Work up as its a full power load, I get 3100 fps in 24" barrel. Groups 1/2 to 3/4" depending on the trigger guy!

Keep us posted.
