That's because the lapua brass likely holds a fair bit more powder. I've compared lapua to peterson in 25/6.5 creedmoor, 6.5x284, and their 30 nosler to adg. The peterson cases all were notable heavier, had thicker necks, and held a fair bit less powder.What strange is in my Lapua brass I can load up to 41 grain before pressure sign but in Peterson I can on get 38 grain on h4350
Not to hijack the thread, but I too am running 142SMK’s in my 6.5x47 and have never considered a Barnes match burner.I've run the 112s In my 6gt, they like to be 60-90k jump for a lot of Shooters, myself included. The 145s in a long throat prc shot the best at 40k jump when I tested. I never went too deap into testing with them as the 142smk was just easy button.
What would be your pick for the 6.5x47?I bought two 500 boxes when NOTHING else was available. I was just using them for fire forming loads, but even then, they are .5MOA bullets. With formed brass loads in a 6.5SLR, they are .4MOA. I got them for $166/500, so hard to pass that price up. I have about 400 left, and have another 350 pcs to fire form. Both my 6.5SSs, and a .260AI coming up (300pcs).
Great option for banging steel and saving a bit of money.
Bullet choice? For that size case, I prefer a 130gr myself. The 130 OTM is really hard to beat. I load them in my two daughters' 6.5CM and 6.5SLR.What would be your pick for the 6.5x47?
If you're looking for a BC boost, the jlk 135vld runs around a 310-315 g7 depending on the twist/barrel. Bearing surface is very short which helps with speed. I'm able to run them over 2900 from a 28" creedmoor with H4350 and imr 4451. I'll also be running them in my 0.081 freebore saum when I get the new barrel installed over the weekend.What would be your pick for the 6.5x47?
