300 SAUM Imp

I'm not improving it at first, but there's a couple reasons. Lapua and ADG both make brass. The thought was similar to what we see with the BRA....you can run 103s 3050 with either 33 grains of powder or 31 grains, guess which is agging better. This may or may not be too small? I don't know yet, but the brass I formed in my first box rivals lapua 6br for volume consistency. The thought was also about a potential use for light gun...but forming brass at 2850 with 197s is pretty much kicking my ass lol....so we'll have to see about that.

Here's box 1, heaviest end of the lot. I lost case 50 screwing around, so tossed a wsm case in there for comparison.

I'd love to hear more about this as you go. I'm intrigued by the thought of this shooting the 185 juggernaut, or maybe the 200.20x, until custom bullet options show up. I wonder how their raw accuracy potential stands up? A 30-06 shooting 190 SMKs was one of my early experiences with long range, and this feels like a modern reincarnation of that. I've always found the 30-06, shooting 190s with ~55gns of powder to be my recoil and powder consumption limit.

There is custom bullets.....and they will likely suck as it's my first batch!

So I re barreled this rifle to a lighter contour to help out the balance but this time just did a wsm because I wanted to compare apples to apples with ADG brass. The high node is 3030 just like in the saum imp but it takes about 3.5 grains more powder to do it. All tuning and final cold bore test done at 600. Just a hunting gun off a Harris bipod so its hard to say. It shot as well with the saum imp barrel, but based on what I saw with the BRA Id bet on a saum imp for the agg.thumbnail (36).pngResized_20220622_072644.jpegthumbnail (38).pngthumbnail (39).png
