Good Morning to you as well. Funny thing. I have a Fatboy Motorcycle (Harley) with a license plate of MYFTBOY. FYI.

Reloading and Marksmanship together are an Art and a Science. When I first started reloading, I just wanted to hear the gun go bang. Over the last 25yrs, I\’ve studied enough material to get a degree in it. The more you shoot the better you get, but you have to be able to differentiate the difference between the shooter and the ammo. I have good days and bad days, ammo is the same.

I have found that most all powders fit for a particular caliber can arrive at good ammo. Some can be awesome ammo. However, there are soooo many factors that work together to get those groups down to 1/2 to 1/4 MOA. Remember, 1MOA is damm good shooting. It starts with good components. Let me give you an example. If you take a pile of range brass (different headstamps), size it, prime it, fill it with powder with a load recommended in a manual and top it off with a decent bullet, and then run it through a chronograph, you will find that the velocity varies dramatically ( ~ 150 fps, tested). Now, if I buy Nosler, Norma or Lapua in bulk, separate cases by weight and run-out (case neck thickness), uniform the primer pockets and flash holes, seat the primer .002 from flush, use some high end bullets, choose a bullet profile that works well in your barrel, perform ladder testing at .2 to .3gr increments to find the velocity node (which means the spot that has a dramatically reduced velocity spread), and find the seating depth the produces the best accuracy, you will arrive at ammo that has the capability to shoot 1/4 MOA with velocity spread of 15fps and a STD 4.4. The difference between these two sets of ammo is that you can put them both in a vise and shoot them at 500yds and the first group will string vertically (8 to 10 inchs) and the second will be 1/4 to 1/2 MOA. Thats just taking the shooter out of the equation. You also have to have the right tools to measure things.

That said. I bought the RMR 69gr bullets because of the price. I developed the load I mentioned with 69gr SMK. It shot exceptionally well. People use the SMK because it shoots very well in most rifles, and that\’s because it has a forgiving, Tangent, bullet profile. I dont know what the bullet profile is for the RMRs, but it looks like its closer to Tangent??? I will have to test for accuracy and compare the two. Keep in mind that the rifles I am talking about above are high end long distance rifles that I built for that purpose. The 5.56, AR 15, is not build for accuracy. Its designed to get a lot of high velocity rounds down range fast. If you get a AR 15 to shoot 1 MOA, call it a day and move on with your life.
