I load 308, 30-06, 30-30, 270, 243, and 300wsm and I'm an incredible creature of habit so changing powders is difficult for me LOL. However, the suppliers as we all know are hit and miss for my go to powders. I usually use IMR 3031, 4064, 7228ssc, 4350, H4831sc, and R-19. Does leverevolution and superformance compare to the above listed powders? What are the perks of these two powders?

Thanks

Keep in mind that I'm as new to reloading as one can be, but the only perk (that I know of) with leverevolutuion and superformance powders is that they are more easily found in the stores than the other more popular, more versatile powders. Take that with a grain of salt, though.

I've reloaded both Leverevolution and Superformance. Both work well. Leverevolution is relatively fast burnng with a speed like Hodgdon BL-C(2), and Superformance is slower burning and like H4831. Both are of high energy and load density. They are worth trying.

I have used Leverevolution in my .308 mod. 99 and Mod. 94 SRC in 25-35 with good results..Also have had good luck with CFE223 in both of those calibers, but got high pressure in with both calibers at max loadings. I backed off a grain or two from book max and all went well.

With many of these new powders use the Hodgedon new addition magazine reloading book, that gives you pressure and velocity for recommended loads with both of these powders..

When these powder companies come out with new powders its not uncommon for them to load them pretty damn hot and that stirs up the masses on the sale end, then later they drop the load down to where it should have been to start with..So do the loading companies on ammo..I don't know if its by design to garner sales, or if the public gives them a wake up call. The 243 and 458 were prime examples back when, and they folks complained bitterly, and the factories back off the load and lowered the velocities a good deal.

Bottom line is you as a reloader must make those determinations for yourself and sometimes it works just the opposite way and you actually improve your loads by increasing the loads, I have many loads that are a couple of grains over book max.

These pressure problems will crop up more when you load for auto, simi auto, lever, and pump guns. On bolt guns the lock up is stronger and it can occur but not often.

Superformance in Gas Operated Firearms " the gun is still in the process or firing while it’s trying to extract the cartridge case." Link from Hornady

I guess it is easier to say some systems work better with Superformance ammunition than it is to say some systems DO NOT WORK WELL with Superformance ammunition.

quote:

However, Hornady ballisticians have conducted testing with a variety of guns (including guns equipped with suppressors), and our findings conclude that some systems work far better with Superformance ammunition than others.....It’s a timing issue.......If the firearm and the ammunition are not in sync, there can be what is commonly identified as “pressure signs” on the cartridge case. This is exhibited by the movement/marring of the head of the cartridge case, cratered primers, flat primers, ripped or ruptured cartridge cases, “popped primers”, and/or any combination of these effects. If any of these “pressure signs” are apparent, stop firing immediately....

Seems like what they ought to be saying is, "Do not use Superformance ammunition in firearms with carbine or mid-length gas systems or with systems using a suppressor".

Thanks for the great info. Looks like i will need to put in some bench and range time to work up some loads...oh no thats just terrible news!!! Actually with the cold spells and snow, my wife is really going to like having me out of the house for a bit. Winter and cold probably the toughest thing on a marriage LOL!!

Thanks again

I've tried the LeverEvolution powder in my Marlin 336C with multiple makes and models of bullets in the 150-170 grain range and never found anything the rifle liked.

Of greater interest to me was that there was no difference in velocity when I used the LeverEvolution powder. One of the reasons I tried it was the supposed increase in velocity, even in shorter barrels. But for in my case, it wasn't there.

I'd be interested to hear what velocities you get with the loads you work up.
