1st time lucky

[Thoburns]

Home loading for over 40 years and never had a result as good when trying a new load. Moving the 308 over to copper, barnes tsx 130g, N140, lapua new cases Fed 210 match primer seated at the same length to the ogiv length of my 150g sierra game kings that shoot very well. Loaded 3 x 3 shots of low, med then higher.
The 1st 3 grouped 1/2", then the 45g <1/4" and doing 2515 that will do for me didnt bother with the last 3. Happy days! Should be a decent deer round

I like the 130g /N140 mix

Update on the speed, just looked back at the chronograph data and they were doing average 2815 fps not 2515. Out after the weekend for live testing

Accuracy is awesome, the speed is too low in my opinion, they will lock expansion unless the deer is close.

Ideally copper needs to leave the barrel at 3000 fps or more.

Edit, just saw the 2815, better but still not quite there, you don’t mention barrel length but 130 gr in .308 should be able to do 3000+ if your barrel is 20” or more.
