Well my 25x47 Lapua has arrived and it didn’t take long to get started with this one. Was pretty eager to try a x47 Lapua for a few years now. I’m new to the cartridge, actually new to this family of cartridges. I am planning on trying rl16, h4350, varget, n150 and possibly n140 to get some information on this caliber.
To break in the barrel I started with rl16. I picked a random charge of 37.5gr behind hornady 134gr eldm and the results were staggering. I don’t know if I’ve ever gotten lucky like this.
First 3 shots out of the barrel

I didn’t have a chrony that day so I threw up a target at 740 yards and dialed what I thought they might be running and held straight up hoping to find splash for elevation and wind. It was easy to spot trace and easy to spot the splash. I made the correction and sent 4 quickly to just make sure I got the call right and had a .4 moa group at 740 yards. Realizing the potential I ran home and loaded the remaining with the same charge to just break the barrel in and once fire some brass. Upon return a few hours later I shot this cold bore 740 yard group then moved to 600 for a nice 5 shot group
I went on to shoot a long range ladder test the following down
A little pressed for time I loaded 5 rounds for both the low and middle potential node and shot 5 shot groups over the Chrony at 100 yards before having to go pick up the kids. First node shot 2700.2 fps with an sd of 5 and es of 13.3. And the middle node shot 2781.3 with an sd of 2.3 and an es of 6.3.
View attachment 1606519I have loaded the upper potential node as well and will shoot it at 100 and then shoot all 3 at 600 yards to confirm.
I am loading up ladders of rl16, n150 and varget with the Berger 135’s to hopefully shoot next week.
