25x47 Lapua

You’re getting great speed and accuracy out of your VVN540 loads. I wonder if N140 would work as well, and give you longer bbl life? Albeit not with the speed you’re getting.

Yea, it's doing well with speeds and accuracy is great but honestly I feel the reamer has a lot to do with that too. I have 140 but I don't think it will do quite as well as the 540 although as you mentioned barrel life will probably be less.

Who made the reamer for you, did you spec it out yourself, or did they already have it?

Here you go. This is the target from yesterday checking seat depth.

You’re correct, your rifle really does like N540! And with either bullet too.

I may have to go get some and test it out…. I have another barrel in .257 but it’s a Bartlein, same twist just with a different profile, M24/40 vs HV#17 on the Brux. That was because I’m using a Deviant Elite Cone nosed CF that uses a longer tenon of about 1.85” in length. And the Brux has a 5” straight 1.25” before it begins to taper down to the OAL of 27”. It was the heaviest I’ve used and frankly for an open heavy NRL rifle is wasn’t the best choice but I still make the weight class limit at 16 pounds.

My builder spec'd the reamer and has not released the info OLD DOMINION CUSTOM RIFLES WSMNUT here on the site.
