I have a great auto-calculating excel spreadsheet with part #'s, weights, price, origin, etc
Reference:
AR15 Parts Weight Database (thanks Bigs28)
Goals:
Less than $2k - money doesn't grow on trees lol
Weight (7lbs with Optic)
Sub MOA handloads
Great trigger
Mobility (can't have a 42" barrel, Missouri forests are dense and sometimes hilly)
Expected engagement ranges < 150 yards
Rare engagement range perhaps up to 300 yards, beyond that your eyes are better than mine at spotting deer
Wild hogs are an actual concern/threat
Build List:
12/31/18
Lower is complete.
Only need a few more parts before upper starts going together, will post pics soon
12/25/2019
Build complete!
7lbs 1oz
11/09/2020
Build complete, range testing well underway, complete tackdriver (after faulty barrel replacement)
It seems to LOVE 120gr Speer, 123gr SST, and 120gr ELD-M with A2520 and 8208XBR.
Factory Load Info:
#81528 123gr Hornady ELD / 2480fps / 0.6 MOA
Hand Load info:
It likes the following loads (for hunting), all with CCI41 primers
27.4gr 8208XBR / 120gr Speer / 2415fps / OAL 2.260 / Elander mag
29.6gr A2520 / 120gr Speer / 2400fps / OAL 2.260 / Elander mag
29.4gr A2520 / 123gr SST / 2475fps / OAL 2.250 / Elander mag
28.5gr A2520 / 123gr SST / 2410fps / OAL 2.250 / Elander mag
Did not like:
Nosler in any recipe, just terrible groups.
Final cost approx $1600
Public Service Announcement:
It definitely seems 2500fps is the speed limit for this length of barrel.
