Becoming a bigger fan of Accurate every time I go to the range. Meters well and consistently even in my old Lyman #55, it has shown consistent velocities and outstanding accuracy. 2495 is a versatile powder with excellent ignition characteristics that provides excellent shot-to-shot consistency. NRA High Power shooting disciplines, as well as heavy bullet 223 Rem target applications. The final thing that swayed me was this:Īccurate 2495 is a single-base, extruded rifle powder that was developed for the 308 Win and can be used over a wide range of rifle calibers. So I got out the phone and did a little looking at burn rates and reviews. Used a lot of AA#5 and #7 and even #9 but not the rifle powders. (I'm not willing to gag for a couple hours at the range just because I'm desperate for powder) A while back I saw a couple lbs of 2495 in the local gun shop and was really hesitant as I had never used any of Accurate's rifle powders. Varget worked ok but the ammonia smell was. The powder shortage forced me to try other powders. Unexpectedly good results sometimes come to the fore.Ĭlick to expand.I'll be the first to admit, I have prob'ly gone through a half a ton of 41 over the years. Don't be afraid to buy one and experiment with it. I've mentioned 5 of what is likely DOZENS of propellants that should work well in. 308 nor any other rifle round, but would expect it to work well in all the 'medium-capacity' centerfire rifle rounds. I don't know which of these has the most similar burning rate to AA-2495, but it's likely close to one or the other. Someone mentioned AA-2495 which, I assume was marketed to compete with either H4895, or IMR-4895. It isn't famous for metering especially well, but it often reveals stellar accuracy in rifles that don't seem to group well with other propellants. It may also prove to be more economical than the other powders mentioned. IMR-3031 is the fastest-burning propellant that is likely to give you full performance with all bullet weights. These two may yield slightly higher velocities than H4895 with heavier projectiles, especially in longer-barreled bolt actions. They are otherwise very versatile propellants, and work well in gas-auto rifles.

These are both slower-burning than Hodgdon H4895, and the '60 % Rule' is inadvisable with them. IMR-4895 or Varget would be my next choice. Other faster-burning powders may also be usable in this way, but I am most familiar the use of H4895 in this respect. Additionally, it can be used for lower velocity, lower recoil loads with cast lead projectiles, using the '60% Rule' per Hodgdon's recommendations. If I could pick ANY propellant for it, it would probably be Hodgdon H4895, since so much work has been done with it (USAMU, etc.), and it seems to work well for all bullet weights. IMR 4895 load with a 168 SMK in the MWS is a lot more accurate than I am.

I haven't tried EVERY propellant within that range, but I can think of none there that I would hesitate to put to use in. Personally, I think any powder with a burning rate between IMR-3031 and IMR-4320 (including those) should work well in. 45 ACP in the sense that it's more difficult to find propellants that DO NOT work well in it, than to find one that DOES. 308 is that it's the rifle equivalent of the. In my opinion, when working with subsonic rounds, you want to use the heaviest bullet you can stabilize since you are going for 1000 fps 125's are a bit light, might as well run those as fast as you can.The NICE thing about the. Also, if you don't see a hole in the paper, don't fire another round until you make certain that last one left the barrel. If you don't have a chronograph, you should probably not be doing this as it is very important to know how fast they are actually flying. Start at 7 grains and work up or down, probably down, to get around 1000 fps. My advice is if you are dead set on trying it, stick with Trailboss powder. You could try Trailboss with 125's in the 308, but I would bet it will only take 6 grains or less to keep it subsonic and that will leave a lot of unused room in the case again, the 300 BLK case is much better for that. It will stabilize a 168 Nosler CC in my experience, but thats about as heavy as you can go in an M14. The barrel twist rate in M14's is not fast enough to stabilize 220 SMK's subsonic like it is in a 300 BLK. Its not hard to cycle an M14 action by hand, but it is very noisy, much more so than the sound of a 1000 fps 168 grain MK going down range through a suppressor. The loads will not cycle the action where they will with a 300 BLK. Click to expand.Actually, you can get 300 BLK velocities with a 308win, BUT its really not a great platform for it.
