308 Win load info

Are you not interested in seeing if that group can be improved on ? Perhaps a few rounds shorter and longer, just to see ?

Pretty much as you predicted, you also said start lower for safety, one of your mails gave exactly this prediction.

Here is the QL calc. Max pressure for the 308 is given as 62K psi, but I leave my pressure at 60K as shown in the calc below. I have added 10fps for the distance to the chrony. The calc shows that the load is exactly on the node. Compare the barrel times.

2554 fps

What speed did you get on the chrony?

Total load development to animal = 6 bullets
1 x fouler shot and chroni reading
3 x shots for group - load development ended right there.
1 x shot 2 clicks left
1 x shot Impala

Got this result with S341 - 42 gr at 61.63 Comp
First shot fouler is the high shot, was also over chroni for velocity.

Thanx Tripodmvr

;D ;D

Sorry, can't help.

Sorry DSJ bad setup was preoccupied with work when posting.
Have fixed it.

Does anyone use this combo? What is the load set up for your weapon, I always like to have various examples of other parameters before I start on loads.
I have Sierra 180 Game King load and PMP load recipes to compare against, now hoping to have someone else's load specifically for this combination.

Slightly lost here.

Do you have 180gr Sierra GK, and want comparable PMP loads for 308?

Or do you have another bullet in mind, and only 180gr Sierra GK to compare against?
