RDW, I don't have a really accurate scale, just a sping type meat scale but it was right at 6 lb 2 oz best I could tell with the Talleys. It is a #3 contour
The 243 AI weighs about an oz or 2 more with a 1" shorter tube.
I was a little spooked by the amount of copper I was getting with the Brux with the first few shots but after 8-9 it cleans up really easy.
It is my first Brux and it shoots 123 SST / AMAX and 140 Hornady Interlocks sub .5 fireforming.
I had to try 3 with fireformed cases using a load that has proven to shoot in my Borden 260 AI and that group went .317".
