    Dummy mistakes reloading today...

    So I reloaded 20 rounds of .308 today. Used AR-Comp because the recipes called for several less grains than Varget, so I figured I'd go with the stuff that will go farther. Holy hell, I didn't realize larger caliber shells/dies were more finicky with lube. I ALMOST got a case stuck and I DID get the stupid decapping pin stuck in one of the cases. I had to destroy the case but the pin came out no problem. Reset the pin and torqued it down really tight, got more generous with the lube on the cases and everything went really well.

    I loaded 20 cartridges altogether, in batches of 5. Started off with the starting load of 37.3 grains (took Alliant's data and subtracted 10% like they suggested to get the starting load data). Second batch went up to 38 grains, then 38.5 grains, and finished on 39 grains. Can't wait to see how they go...the starting loads are just to see how the rifle functions with cycling and locking the bolt back, etc. Just going to load one at a time.

    It was a real pain in the *** getting everything set up on this particular caliber, but once everything got dialed in, it went beautifully.

    Then on to metering the powder. I have the Lee Perfect Powder Measure. I had been using it with Varget for .223 plinker loads. It was metering 26.5 grains of the stuff perfectly. Well, I kept getting very inconsistent throws with the AR-Comp. No matter what I'd do, it would vary by up to 4 or 5 grains! I was getting kind of worked up and frustrated, checked the scale and it was accurate (double checked it against my beam scale, everything matched up). So then I thought it was the powder measure...I had almost given up when I noticed something...the powder was taking longer to drop than with Varget. As in you throw the arm up...then actually wait a couple seconds, before pulling it back down. Once I got that technique down, it was throwing perfect consistent loads again.

    Moral of the story is...take your time, become intimate with your equipment, remain patient, and don't make stupid newbie mistakes like I did. I'm posting this hoping someone will read this, maybe get a laugh, and not make the same mistakes! Hopefully I made them so you don't have to.

    Have fun and be safe!

      Dropping consistant loads from a measure has much to do with consistancy of technique of the user.

      My measure is mounted solidly to the bench. That is important IMO. I 'bump" up, and down, on the handle. Which is to say, I lift handle slowly, then bump it against the top of the throw at end of stroke. Then, when lowering the handle to pick up the next charge, I again start slowly and "bump" it against the stop. Not hard, just a bump. This keeps the powder settled in the measure and improves consistancy of drop.

      The more consistant you are in your movements, the more consistant your drops will be.

        The only mistakes I made today was tilting the big pig funnel too far one way and not paying attention and thus dropping my blue balls all over the floor...

          Oh yeah, I figured that out the hard way. Even though Varget and AR-Comp are both extruded powders, they meter very differently. I was trying to meter it like Varget but it didn't like that...once I learned the powder, it was good to go!

          What you're describing is how I meter Varget, but I don't pause on the stop at the up-stroke. Just up - bump - down - bump and I get the same throw within a tenth of a grain just about every time. With AR-Comp I had to go up - bump - pause for a few seconds - down - bump and it metered perfectly.

              Just be SAFE, take it slow, be thorough, and follow the directions...then hopefully the worst mistake you'll make will result in having to clean up a mess on your work bench/floor.

                My recent mishap was finding half a pound of powder had somehow spilled out in the trunk of my car. I have no clue how the cap came off the bottle.

                    I've seen some comments about how Alliant's (very limited) load data for AR-Comp isn't the maximum but rather the optimum. When I loaded for .308 I found my best charge to be very close to their published number.

                      Directly from their web site. Interesting, though. I'll have to see how it goes at the range.

                        I also have the Lee Perfect Powder Measure and use it for IMR 4064. The technique that gives me the most consistent drops is tapping the handle with my finger five times on both the up and down motion. This helps the powder to settle in when the handle is raised and fully drop all the powder when the handle is lowered.

                          I just finished yesterday loading up some 50 rounds of .308 with LC brass and using IMR4064 along with 168g. of Hornady AMAX and some 168g. of Sierra HPBT. But, as the Lee Perfect Powder Measure I have, its still in the original box for the passed two years. I have found that a digital scale, in my opinion, works better and much easier and probably just as accurate if not better than the Lee Perfect Powder Measure.

                            Yeah, I've been using the PPM and a digital scale to verify loads, along with a trickler to get that exact number.

                              I start reloading 308 this week for my bolt gun. I decided to load for this gun single stage to make sure all rounds are damn near the same. Can't find Varget right now so I found some IMR4895 hopefully all goes well during the testing. Ill be using SMK 168 HPBT and will post results.
