.308 LRTR Loading Process
Long Range Tactical Rifle
Priming, Charging, Seating the final steps
Now that I have prepped the cases, I can load up my rounds as needed. I try to keep all my brass prepped and ready to load.
I will detail as much as possible, and again, some of what I do, I don't know why, other than that's what I've read or been told. But you have to start some where, so here it goes.
Here's the equipment laid out and ready to go. Primers, powder, cases, scale...
Step 1 - Priming: I load up 10 to 20 primers in the Dillon pickup tube and dump in the primer tube. Then I seat 10 to 20 cases slowly and evenly in the 550 press.
Step 2 - Charging the case. After I get 10 cases primed, I put them in the loading tray and measure the powder by hand using the following components:
- RCBS Uniflow Powder Measure with baffle
- PACT Digital Precision Powder Scale - I am going to add the Pact Digital Precision Powder Measure in the future, this scale has an infrared port for the external powder measure.
- Hornady Powder Trickler
- Hornady Powder Funnel
Step 2a: I throw a charge that is about 2/10th a grain shy of the load desired. Sometimes I get lucky and it ends up being a dead on load, but usually not.
Step 2b: I put the charge on the PACT Scale and add with the Trickler until correct charge is measured, In this case 44 grains of BL-C(2).
Step 2c: Then I dump the charge in the case with the Hornady Powder Funnel, and check each case visually.
Now I'm ready to seat the bullet. Back to the 550. I am using a 2nd Toolhead that has 2 dies in it:
- Redding Seating die
- Redding Taper Crimp to remove the slight bell that I put in with the Lyman Type M Die.
I eventually want some sort of powder funnel that I can put in the 2nd die slot, so that I can prime, drop a measured charge, seat and crimp in quick succession.
Step 3 - Seating the Bullet: I am using Sierra MatchKing's, these are 168's, 175's are next. this is where the Lyman Type M die is nice, because of the slight expansion at the mouth of the case, the bullet sits very nicely and uniform, I don't have to hold it at all.
The bullet is seated using a Redding seating die. I was seating to 2.800" but I was getting to many OAL variations because the tips of the bullets are all just a bit different. Now I use a Hornady Lock n Load (Formaly Stoney Point) Bullet Comparetor to see how consistent my bullets are. All of these bullets are the same, with 2 of them coming in at 2.1195. Not bad.
