Imr 4350 56g gets 2625fps with 20"brl ruger #1 and 2730fps with 23.5" baikal and 2475fps witha 15" encore brl
And in my Husqvarna with 24 inch barrel, it took 58 grains of IMR 4350 to obtain 2642.
This Husqvarna shoots every load about 75, of so, fps slower than does a P17 with a custom barrel.
Thus, the P17 shot the same load with 2731 average.
I have said many times on these threads that I have never seen a US loading chart that didn't lie about their velocities. I have often said that the only accurate loading chart I have ever seen, including Hodgdon on line, are the old charts put out by Norma.
Many years ago I started out reloading and the rifle I had was this same old Husqvarna 30-06, which I later found out shot a bit slower than most rifles. I started out using Norma componets exclusively; Norma cases, powder and bullets, along with the German RWS primers. My first, and actually the only loading book I own, was Norma's, "Gunbugs Guide." It had only 25 pages, including the loading charts, but it got me efficiently and safely reloading rifle and revolver ammunition over a period of nearly fifty years. The Norma chart showed 50 grains of their 203 powder in th 30-06 with 180 grain bullets for 2700 fps.
I used that load exclusively for years and won some rifle competitions with it. I often wondered what velocity it gave and years later when I had a chronograph, I managed to get a pound of Norma 203. I chronographed if and with same load of 50 grains and the same old Norma 180 grain bullet, it gave 2642, in the same rifle that I had found out, always shot a bit slower than other 30-06 rifles. So, it really was giving 2700 fps, just like it said.
I later checked other velocity figures in the Norma book and every one was either dead on, or a bit more than it showed.
