ASYM 45acp National Match 185 Nosler




I bought a couple boxes of ASYM ammo to try in my SR1911, and the results were excellent with POI=POA, fairly clean, feed and ejected perfectly.

The description on the website states they use VV powder. Does anyone know exactly which powder is used and the charge?

The procedure...

If it is a VihtaVuori powder:
Shoot some across the chrono for velocity.
Pull a cartridge down and weigh the powder.

Only one VV powder will get that velocity at that charge
for a given weight bullet at the cartridge OAL.




Of course, compare the powder visually because it may NOT be VihtaVuori.
There are more rumors and guesses than actual fact
when it comes to the powders used by commercial manufacturers.

We often say that the ammo companies use uber-unobtanium powder.
But some ammo mfrs use bulk powder totally identical to our canister powders,
and other ammo makers use powders we ain't never seen before.

There is no single rule that holds true in each and every case.

... Or you call Asym and ask. They'll tell you.


Incidentally, Nosler ballistics lab says a light charge of AA#5 (8.6 grains)
is the most accurate powder they tested with that 185 gr Nosler HP.
This is shooting from a 5" barrel with 1/16 twist, Federal 150 primer
at OAL from 1.190" min to 1.275" max.

I haven't chronographed this load but it was very accurate in my DK1911.

Bullet: Nosler 185 gr. JHP
Powder: VihtaVuori N310 4.45 grs.
Primer: Winchester Large Pistol
Case: Federal
LOAL: 1.225
Recoil Spring: 16 lbs

In my Performance Center 1911 this load shot even better. I'd use a 15 lb recoil spring without the Shok-Buff.

Bullet: Nosler 185 gr. JHP
Powder: VihtaVuori N310 4.3 grs.
Primer: Winchester Large Pistol
Case: Federal
LOAL: 1.225
Recoil Spring: 13 lbs (With Wilson Shok-Buff)

It is unlikely the are using a canister grade VV powder.

It is likely a bulk grade that is similar, but NOT exactly the same.

It might even be an 'out of spec' lot of canister grade.

They are NOT paying canister grade prices.

Even if they told you the powder, getting the same lot is not likely

Let's clarify what it says on the web site:

Quote:
We use premium powder in our loads. Top shelf VihtaVuori powders are used extensively, as well as high performance, clean burning, non-canister grade OEM powders made in the USA and Belgium.
They don't say that the VV powders are non-canister grade.

They say that the powders made in USA and Belgium are non-canister grade.

It sounds like the use lots of different powders.

So your 185 grain 45acp ammo from ASYM may not have VV powder.
It may have commercial powders from USA or Belgium.



Unless you tear one down, and then call ASYM to discuss it,
you really don't know anything for sure. All the rest is guesswork.

I did just that; but I also bought some N320 that I will use to try an duplicate the load. If not, I'll try N310.

I tried both N310 and 320 with other 185 bullets and 310 was definitely the best choice.

I chronographed one box of Asym and got 710 fps which seemed slow
