Wanted Lapua 300 Winchester Magnum Brass

From what I’ve heard and read is that Lapua never made 300 win mag brass. It was Norma that made it for Lapua in a small quantity. The Lapua stamped 300 win mag brass was made by Norma

That being said, the Gunworks brass and Norma brass has been great for me and others I’ve spoken with. Can’t speak to the ADG brass, never tried it, never in stock
 
After doing research for 300wm brass and finding that I'd be limited to a good quality brass as I'm us to using lapua in other rifles I chose the adg and liking it. I'm about to prep it for its 3rd firing.
 
Just an FYI. I’m not so sure Norma made Lapua 300 WM. The Norma weighs 215 grains and the Lapua weighs 260 grains. I would assume they would be similar in weight if it were manufactured by the same vendor???

ADG is good chit in 300 WM, very uniform and durable(only caliber I have tried so far). I weighed 100 cases in a lot and I think the difference from high to low was something like 3.5 grains. Very consistent. Have not had the opportunity to try Petersen but hear its quality too.
