    Ideas for precision AR-15 build?

    So I recently built a cheap .223/5.56 AR 10.5" barreled 'pistol' upper and brace lower to complement my 8.5" 300 blackout pistol, and I have to say it really sucks and I am not impressed with the ballistics or the accuracy. (I have been spoiled by a top end semi AR-10 6.5 Creedmoor build.) It...

    Talk me out of a Kestrel and Sig BDX Rangefinder.

    This is what I have now to set up my shots: For temperature and humidity, I have a Honeywell sensor that came with a humidifier. The accuracy is questionable, but it's better than putting %50 in. For wind speed and temperature, I have a small handheld wind unit that I use for sailing. The...

    Gunsmithing NFA Question: Would this build constitute a Title II firearm?

If one were to build a weapon with the following characteristics, would it be an NFA Title II firearm? 1. Utilizes a AR-15 type lower receiver...

    6.5CM Hornady Brass Life and Loose Primer Pockets?

    I've got a couple hundred Hornady 6.5CM cases that I've shot four to five times. Recently, a good number of them have loose primer pockets, loose enough so that when fired the primers fall out and get lodged in the chamber or where the bolt locking lugs are supposed to go = failure to chamber...

    Tools to parse Magnetospeed V3 data file?

    So the Magnetospeed V3 puts out data file that you can load in Excel and that's all good and well It's still a bit of work to graph it all and discover information like speed nodes and such from it. Are there any programs out there that you can upload the data file into which will produce a...

    Made a cheap $50 lathe for brass prep tools.

    I got tired of running my hand-held drill for spinning brass prep tools and running the Lithium batteries down. I bought some cheap chinese-ium electronics for $50 from Amazon: 18V power supply: https://www.amazon.com/gp/product/B079NJ63SQ DC motor speed controller...

    Some observations on the Hornady 140gr ELD Match and 147gr ELD Match (6.5 Creedmoor)

    Recently I sent away some once-fired brass to Hornady so they could make me a case for their OAL tool. Now I've finally been able to measure the distance to the lands in my rifle's barrel for any given bullet. (Proof Research AR-10 22") When I use a 140gr Hornady ELD Match bullet, the distance...

    General Reloading Process?

    So I've watched a lot of videos and read a lot about how the reloading process works and just trying to put it all together because I might want to start reloading 6.5 Creedmoor for use in semi-automatic, and reload as precise as that will allow. Here's the basic process I've come up with that...

    What are you guys running for ammo in 6.5 Creedmoor gas guns?

    I have a 6.5 Creedmoor large frame AR with a Proof Research 22" barrel, and all moving parts are JP internals. Thunder Beast CB .308 brake. Mine has about 120 rounds through it and I followed the shoot one / clean one break in for the first 30 rounds. (MPro7 Bore Gel) I have tried a whole bunch...
