SBR Reloads

Another powder I’d try is 2000-MR. Been hard to find but it offers the velocity without the pressure spikes like CFE223.

I recently grabbed an 8# of it; works well in .308 and .223 heavy.


I’d be curious to see how Hornady’s SBR specific ammo/powder charge differs from a non-SBR variant of an identical bullet weight. Might just have some additional flash suppressant in it, who knows

I went ahead and bought #8 of TAC even though I want to keep on testing. It checked every box of what I wanted to accomplish. Yes, powder availability has been a big pain so this factored in to the decision to just get some. I have plenty of other powders to shoot but I have had this question in the back of my mind for a while now.

In my opinion there is obviously a market for 'sbr specific ammo', but like I said if you watch that video on the Hornady stuff the velocities were pretty low using the same grain weight of bullet. 180+fps is quite a lot, which begs the question that if I can do it why didn't Hornady? On a side note I am not worried about flash at all. Not even 2% of my thinking worries about flash. LOL.

If I can find 4-5 interesting powders in stock at the same place I will definitely buy them and try, but that might be years away from ever happening. Who knows if I will see powders on the actual shelf locally either. I was going to buy #16 of TAC but I have other expenses coming up so I just did one. It should last me a while to be honest because I shoot/reload more than one type of gun.

On a side note TAC can also be used in 6 ARC so that's a bonus too I guess.

BTW do you have (or have a friend with) a short barrel (10.5, 11.5 etc) that you could test out and get velocity data for?

If I can find people that have these various powders already it would be extremely nice. This last test cost about $250. Given I have a broader assortment of powders now but it would be nice to kind of cut the chase a bit.
