I’m excited to announce a new project we’ll be working through here on http://ultimatereloader.com that will extend some of what we did with AR-MPR, but this time we’ll focus on the “big brother” to the AR-15- the AR-10 platform, specifically the DPMS LR-308B. For optics, we’ll get an up-close look at the Bushnell/Millett TRS-1 tactical scope.
Watch the video to get a preview of what will be covered:
Looking forward to sharing this experience with you all!
Thanks,
Gavin

Let me start out by saying how much I enjoy your site! As the owner of both an AR-15 and and an Armalite AR-10, I’m looking forward to your latest .308 project. A quick question…is it actually correct to refer to the AR-10 as a ‘platform’? My understanding is that the only true AR-10 is built by Armalite; all others (including DPMS) are .308 versions of the AR-15 platform. I know it’s cutting hairs, but the AR-10 guys will be all over you on that point!
Keep up the fantastic work!
Thanks Mark! Good question- I think of the AR-10 as the “first” AR, and the original AR-in-308 platform. I use “AR-10 platform” in loose terms. Perhaps that’s not totally correct. I gues “AR-308″ as a project title is better and more general.
It’s a perfect title if you ask me! Are you going to develop rounds specifically for the rifle you build? How you approach that subject might be interesting for those of us building custom loads. Good luck!
Thanks Mark- yes, we’ll dial in the loads for this rifle (twist rate, barrel length, chamber/magazine dimensions, etc) – precision stuff, and a lot of fun.
Hey people!
I am new to reloading and have decided to go with a dillon. I cannot decide between the 550 and the 650. Any thoughts on this would be most apreciated. Laslty, which is beter for case cleaning, dry media or the wet ultrasonic type?
Againm thansk for any inof you can provide.

Hey Andy,
I have been reloading for many years and I would say it really doesn’t matter which of the dillon presses you get.. The only thing I would throw in from my experiences is that it depends how many rounds that you are going to be producing. I have had the Square deal, the 550 and the 650 I currently am using and I love it. As fare as case cleaning goes I have always used the dry corn cob or the dry walnut shell. Good luck. Chad
I was excited to see your project because I have purchased the same gun (LR-308b). I researched the short barrel on the gun and found that short barrels can actually increase accuracy, but you sacrifice velocity. I was hoping you would address how to maximize the velocity possible out of this barrel. (powder burn rates, gas port adjustment, bullet size etc.) I realize a person can’t sacrifice every thing they want out of a gun just to increase velocity, but I am interested in your thoughts on this question. Thanks Terry
Gavin,
Thanks for all the good work you do. I’ve spent countless hours researching the reloading system I am purchasing. I look forward to following the AR-10 build! I’m shooting silhouette now and given the success of your AR-15 build, I’m inclined to follow your build for my next silhouette rifle!
Keep up the great work!
Dave
Gavin,
Is there a reason why you chose YHM products?
Great project! I have an LR-308 that I have somewhat modified and do custom loads for and I love it. It is so accurate. Looking forward to learning even more from you guys!
