After returning to this thread I have realized that I made a gross mistake in recommending a powder to a fellow shooter. I meant to recommend N133, my goto powder for both .223 rifles. 26 grains of N133 is a miracle in my 12 twist bolt gun.
N150 IS WAY TO SLOW FOR A 53 GRAIN BULLET.
Just goes to show you that you need to pay attention to what you read on line.
Running this combination on QuickLoad shows a very poor percentage of the powder being burned with the 53 grain/N150 combination, probably around 90%, depending on a number of factors. This, incidentally doesn't equate to muzzle flash, as that's almost never actually unburned powder that you're seeing. Muzzle flash is most often caused by a re-ignition of the powder gases as they exit the muzzle. Even thought the powder is completely burned, the powder gases themselves remain combustable. Upon exiting the muzzle, the sudden addition of a new source of oxygen creates what amounts to a secondary explosion, which we see and hear as excessive muzzle flash. Not unburned powder at all, in most cases.
Yep I made a really bad typo. I meant N133.
N133 will push a 53 grain vmax close to 3300 FPS in a 20" barrel( mine anyway) in My 24 inch bolt gun I'm getting almost 3500 with the same load. I should use the review post button before I press submit.
I appreciate your corrected information. I am convinced that your right about hte N133. I am sorry I did not see your reply sooner. and I appreciate your trying to correct it. Say have you had any exposure to TAC or IMR 82208 XBR?
Hey, happens to all of us! On the bright side, your typo couldn't have gotten anyone into trouble, and would have just resulted in very slow, low-pressure loads. I had one of my guys in the range made the mistake of inadvertantly substituting Winchester Action Pistol (WAP) for what he assumed to be Winchester Magnum Rifle (WMR) in a Model 70 in 270 Win once. That's the kind of mistake you only make once. The pic of what was left is shown in the Sierra 4th or 5th Edition manuals.
The N133 is a great choice for this range of bullet weights.
On yours and Kevins recomendation I ordered the Hornady 53gn Vmax and N133. It sounds like the best of all I have considered. I had thought W748 but n133 sounds better.
Thanks for all your input and Kevins too.
