Holy ballz, what is your velocity going to be? Gotta be lazers.
Hornady manual shows a top end of 3,400 with H4350 I'm using.. Barrel is 20" so probably won't get there but should be plenty fast!

About to start experimenting with the NAS3 cases.
I bought 20 round of loaded ammo so I could pull bullets and hopefully see what type of powder they are using.

Charge weight with 150 NBT bullets is 50.5 grains of unidentifiable powder. Looks like a flattened ball powder with either a copper removing agent or a temp stabilization agent. Has that tan/green color like Varget or H4895.

Factory ammo on left, reseated one on right. I pulled the 150 NBT with my RCBS collet die with about the same effort as a brass cased cartridge. The I ran it through my Redding bushing neck die with no issues, set final neck diameter with a mandrel then seated the 168ABLR with no perceivable additional effort above a typical brass cased cartridge.

Velocity data forthcoming.
I really like mineHow do you like the RCBS Summit press? I really don't need a new press but I have a small bench and store stuff under the bench so having everything on top would be nice.
~80fps in Peterson brass, but that’s because I was out of case capacity. The NAS3 cases hold 2 grains more of the same powder. Alpha would typically produce 8-10fps more than the Peterson.Fps gain over Alpha brass load?




Ran quick pressure test on the ADG brass. I hit bolt lift with the Hornady brass at 66.5. I loaded 66, 66.5, 66.7, and 67. I have ejector stamps on .7 and 67 but no bolt lift. I’m gonna load 67.5, 67.7, and 68 and see how far I get.I would be interested in the difference!!
Got up to 68 with light ejector stamp and no bolt lift. MV was 3179. I’m gonna stop there and load 10 and see how it shoots.Ran quick pressure test on the ADG brass.

Empty weight of the fired ADG brass is 230.2 grains. Full of H2O, weight is 311.2 grains for 81 grains total. That is 1 full grain more than the Hornady brass.

I’ve always liked the idea of having an RCBS
Summit press to bring to the range since they brought it to market. I will inevitably try a set up to bring to the range. The only thing holding me back is when I see two others. Hard to decide between the three. Sinclair,Harrels or Summit. I figure the one that gives the least runout will win. One thing against the Summit is the handle not centered; which likely doesn’t affect the press too negatively considering they have developed a reputation for low runout. Still , I like symmetry when you are measuring thousandths (even tenths) of an inch. And I like those nifty and compact C types. They seem so practical. I love that about reloading in general. All the nifty compact tools ( miniature sized) we get to work with. Very cool indeed.
That’s smokinYessir!
