Anybody can give me receipt for this powder?

:) ah OK the spelling, sorry for that I was asking for a cooking book...

What I need is - what weight H380 powder would be the ideal amount for 155gn Sierra Palma for target shooting 300-600 meter rings.
I just made today two dummy amos from a chamber (with loctite method) and finally I can calculate the bullet seater from there.

So Explain your process for coming up with a Super Accurate 308 load please ? RJ

So far I have no process on my own for reloading.
With this my 308 f-class project gun I inherited also from a friend made me a batch of amo that I spent all of it getting familiar with the gun.
He made two different loads for me,
- The first 50 rounds with 46.6 gn with bullet slightly extended, it was kind of OK @ 200-300 below a 1/2 MOA on rings, but at that time I didn't had Labradar data.
The second 50 rounds was with 42.7gn and he pushed the bullets deeper in the neck. The groups got slightly tighter about .4 MOA @ 300, but at that time I already got the Labradar data, the ES/SD was a bit erratic in my eyes.
He gave me all he's surplus reloading equipment a full trunk load, I just needed to buy the die sets, which finally arrived to my hands last week.

Can you post the picture of the target?
If I am understanding you correctly, you are getting 1.2 inch groups at 300m - correct?

Measured with Ballistic-X, but I didn't purchased the license and won't save the image.

This was the first batch, zeroed at 200. The picture shows a jump from 200 to 300 is 19 clicks. The gun was resting on table top tripod and rear PQP rest.

Next batch @ 300 I already got a Rempel rest in meantime and the rear is the same PQP.

I have more target faces from Aug, but wife moved a lot of boxes to garage, I need a work party to dig my targets out.
In Sep I was away and didn't visited the range since.
 
Those groups look excellent. because of barrel harmonics, the best ES/SD loads may not shoot the best. Don't argue with the groups.

Try the same powder charge with 3 different seating depths. If one shoots a better group, use that OAL as "THE" OAL.

Then, using that OAL, try that powder charge and 0.2 more and 0.2 less. See which shoots the best.
 
I just sourced a box of shot shells for aneiling that will be mine own fresh start reloading. Still have one "box" primed but I know not much about history and details because I inherited these.
I made two dummy's from the chamber, will start with minus 0.020" and go from there in +/- increments.
First to order some decent powders ... and extra bullets and primers ... and what else....

Geee, my airguns (.22 and .25) dirt cheap when I see 250 shots a day that cost is like a hamburger ;)
 
Sheesh - The Hodgdon reloading data center (google it) has one of the most comprehensive load databases in the world. BTW - Hodgdon sells both Varget and H380 powders....

When did you check that last time? Sorry to poke, but I cannot find anything around H380+Sierra 155gn
 
Well - There is a reason for that. 380 is sub-optimal (slow and bulky) for the 308 with 155 g pills, giving rise to compressed loads. Varget certainly fits the bill, is commonly available, and well documented in the Hodgdon data centre. Suggest you pick up a manual going forward, the Lyman book is a great resource.

Lyman, Sierra and Speer all have data for H380 and 150gr and 165gr .308 bullet. Pick the lowest minimum starting charge and work up, just because there isn’t a listed load for your specific 155gr bullet doesn’t mean you can’t work up a safe load.

The target pics you posted, what is the bullet/powder combo you’re shooting? Is it the Sierra 155’s and H380?
 
Send me ur mailing info and I’ll send you a Hornady reloading manual and a pound of Varget to get you going. Nice shooting bigHUN. H380 and WW760 are the same powders and work great in smaller calibres like 22-250. As mentioned the Varget or VV will be better and more stable plus easier to ingite. Just pm me and I’ll get it in the mail. I’m only a couple hours east of you so it shouldn’t take long.
