Loading for LR-308

[Sparkylr308]

Good morning. Do any of you guys load for the LR-308? I am curious if you have and tips or tricks for it. When I have loaded 556 ammo I have ran into load data being to soft to cycle my AR. Curious if this happens with 308 as well. Also if anyone has any preferred loads that work well for them. I have in hand 168 gr sierra match king hpbt, varget, ar comp, imr4064 for powder. Thank you!

I really like AR-Comp, was using Varget and reloader but the AR comp was more consistent over the chrono and cycles the 3 different AR308 configurations I have.

@Albroswifti don’t have a ton of ar-comp on hand. Did you like using varget at all?

[edgecrusher]

Varget is outstanding. I wish I could grab more. @98Z5Vwill have some load data for you. I kept loading Mi262 clone loads until I was too low to do a 168/175 load ladder for each. Still looking for more

@edgecrusheroh that’s awesome! I am very glad to hear that. I have a decent amount on hand.

Used varget for years. Nothing wrong with it at all, just getting better SD's with the AR Comp. Maybe a little more forgiving, who knows. Seeing how you have both, work up a couple ladders and make your own assessment.

@Albroswiftok will do. I see what you mean. That makes sense.

And report back!

@Albroswiftwill do! I made 10 rounds the other night. I am gonna try and get to the range today. 

[Sparkylr308]

@Albroswiftupdate: finally got to the range yesterday. Used 168 gr hpbt sierra matchkings. Loaded with 42.1-43.7 gr of imr-4064.~ 2500 with 42.1 and ~2600 with 43.7. Decent accuracy. I will say though they did seem very consistent. I think I am gonna up the charge a little bit. 

[Albroswift]

You are right there for velocity no surprises. Looking up your load, 44 gr is about max. Did you record SD's?

@Albroswifti haven’t ran the numbers for SD yet with this data. The load data I am using has 45.9 grains as max and it’s compressed.

45.9 seems pretty high, watch for signs sneak up slowly. Nothing wrong with slightly compressed loads as long as you don't start deforming the case. 168 Sierra shows 44 max on loaddata, but 168 Sierra HPBT does show 45.9.  I like to see SD's when I'm running a ladder, fastest isn't always bestest.

@Albroswiftthat is Data from hodgon website I was using for quick reference. Yes I agree. Just need more bench time hahah.

I use 44.5 of Varget under a Hornady 150 gr FMJ-BT with awesome results.. great powder.
