Phase III of the AR-MPR AR-15 rifle project is really all about “precision mass production” of the ammunition that we’re developing in Phase II (precision single stage loading). There are a couple key things that we’ll explore: first, we’ll look at progressive reloading of .223 / 5.56 ammunition. We’ll also extend our production rates by adding the RCBS rifle bullet feed kit. This is going to make for some very efficient reloading sessions! It will be interesting to compare the characteristics of the progressive loaded ammunition against the single stage loaded ammunition.
So I thought it would be cool to show you all a sneak peek of the RCBS rifle bullet feed system that we’ll be using. I’m new to this piece of equipment, so I’m looking forward (as always) to setting it up, experimenting with it, and seeing how it works on progressive reloading presses. Should be a lot of fun!
Meanwhile, I’ll be posting range reports for Phase II (videos are done) that will track my progress towards “consistent 5-shot .5-.75 MOA” groups. The last couple trips to the range have been a bit challenging, and I just now discovered that I had some serious foaming bore solvent crud build-up on my muzzle crown (under the muzzle brake). Ah-ha! I’m hoping that will get me back to the kind of consistency that I was seeing at the first range trip (right before I used foaming bore solvent – not a good idea on gas guns- now I know why 🙂 ).
So stay tuned here on Ultimate Reloader- we’re going to be exploring some cool equipment scenarios, and I have another upcoming project to share that will be a lot of fun as well!
