[QUOTE="MajorSpittle, post: 1472077, member: 53101"] Perhaps SuperFormance for 30-06 is the real deal! So I thought I would post my first results with the Superformance and 208 A-Max out of my Tikka T3 Lite. I loaded up 55 - 57 grain loads with .5gr increments to test it and loaded them out to 3.355 COL in Fed Neck Sized brass with WLR primers. These are shot off bipod over a Cadwell Chrono about 10 ft from muzzle. 5rnd groups. 55 ran at 2647fps w/19stdDev grouping ~ .9 55.5 2668fps 8stdDev grouping ~ .7 without 1 flier 2" low and left? 56 2691fps 8stdDev grouping ~ .8 without 1 flier 1.5" low and left? 56.5 2717fps 14.5stdDev grouping ~ .8 without 1 flier 1.25" low? 57 2738fps 13stdDev grouping ~ .75 without 1 flier 4" low and left; and one 1.25" high and to the right. I was shooting pretty ****** and the tilt lock on my bi-pod was unlocking which may have been the fliers, that and I kept changing my position and hold on the rifle because I had a different scope mounted that was too far forward. Thus why I eliminated the gross fliers as I hope it wasn't my 1/11 twist barrel not stabilizing rounds or load related. I see once again I am over book velocity with Superformance but a more reasonable 50fps. There was no pressure signs that I could find on primers or heads. I also loaded up some different flavors of my 58gr IMR 4831 168 A-Max load to see how it would shoot. First time trying load in different neck sized brass with different primer and increased COL on load. They all shot the same (45 fps faster with WLR primers vs the CCI) and more accurate then me. I also threw in some 178 A-Max over the 58gr IMR 4831 with the same COL and you couldn't tell the difference in groups other then they were .2" lower and 25fps slower @ 2754fps. Step #2 for 208 A-Max I finished loading up sets of 56, 56.3, 56.6 of Superformance with increased COL of 3.374" (I filed down the inside of the plastic Mag to give me .040" more length). This should put the bullet .036" off the lands. I also on a whim decided to load up a set of 56gr IMR4831 with 3.38" COL. If my lot of IMR4831 with WLR primers scales linearly from the 168gr A-Max I expect a MV ~ 2550 and really hope for more bug hole groups. I am really impressed with the Superformance, a 208 A-Max @ 2700fps out of a lightweight '06 with a 22.5" barrel and not a hint of pressure is not normal IMO but that is only 50fps above book and under the book load. I am really curious if this is typical for the powder? With the Velocity, availability of the powder, and the price they sell it at I can only assume that it is manufactured from the tears of liberals. Strangely I haven't seen many people speaking it's praises on the Interwebz. Please chime in with any experiences you have had with Superformance or any tips that can make working these up easier/better. [/QUOTE]
