Suggestions please for 6.5 Creedmoor powder / data

[Chris J]

Thank you for that data. I picked up the powder, dies etc this w/end. I’m going to try 139g Lapua Scenar bullets. I’ll be loading up this week using .2 increments from 41-43g hopefully to find a node that I can work from. I’ll start with the Hornady brass that I have using large primmers. I have to ask: what is the advantage in using smaller primers for this caliber?

Personally I'd go for .5 gr to start off with, that's what I always do in anything bigger than .223, or you'll be spending forever testing. Once you find the best charge weight you can then try .2 either side to see if it improves things.

Small primer pockets and flash holes make for stronger brass, most reports on the hornady brass have the primer pockets stretching and failing after a few firings. I have .243 fed brass formed into creed with large primer pockets and they are getting loose after 4 firings, this will be the last loading before they're binned.

Have a couple of hundred sako once fired, will be interesting to see how many firings they last.
