Finally got to take my Ruger tang safety with a new 26" Shaw barrel 308 Norma Magnum to the range for a few test loads to see where it's at.I was quite impressed with the velocities.Groups where OK at 3/4",but a little load adjustment I think it will do better.I was expecting about 100fps less velocity,but really it was about as good as I'd expect from my 300 Win Mags.I think I'll try dropping down a grain or two to see if they tighten up,but I really didn't see any pressure signs with these loads.I shot one round with a 180gr Nosler Ballistic Tip loaded with 71.0grs of Hunter and it clocked at 3105fps.I used necked up Winchester once fired 7mag brass for my loads.I do have some Norma cases coming,so I'll have to compare the case capacity of the brass once I get them.There is just not a whole lot of load data out there for the 308 Norma Magnum and there are a lot more powders out there as well as bullets since the original data was compiled.I'd like to see a Quick Load for the 308 Norma Magnum,26" barrel 168gr Nosler Ballistic Tip and 180gr Nosler Balistic Tip.I have plenty of types of powder,I'll most likely be trying A-4350,IMR-4350,Hunter,Reloader-22 and Reloader-26.

Very nice. I bet RL26 will really make her sing.

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.

or a maximum loading ratio or filling of 112 %
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 !

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

Thank You Dr Mike!!!That is going to help me a lot.I knew those loads were at or a tad over max when I saw those velocities I was getting.When I look at that Quick Load data it looks like it's spot on with the velocities I was getting with my Magneto Speed.Shows you also how a chronograph is a good tool to judge if you can bump your load up or back off a bit.In my original post,I posted I wanted to back down.I look at that Quick Load data and I see very little difference between the 308 Norma Magnum and the 300 Win Mag.I have both and really like the 300 Win Mag,but in this particular rifle I chose the 308 Norma because of the rifles short length mag box.I think it was a great choice.I also chose the 308 Norma over the 30-338 because I could make my brass from 7mag or 338 Win Mag brass or use Factory 308 Norma Magnum brass that is a little longer case than the other two.7mag or 338 Win Mag brass gives you just a little shorter case,but it really doesn't hurt since chambers tend to be a little generous in that area.
