What's Wrong with SW Match Rifle Powder?

[Harpoon1]

I've done searches here and on google, neither turned up very much.

I've seen our fearless leader BFT say Bill Alexander told him that A2520 was the best all around, perfect Grendel powder.

The Western Data book shows it as the fastest powder in all the lower Grendel weights. And from what I can find, the Shooters World Match Rifle is ?exactly? the old tried and true A2520 formula!

So what gives, why so little data with it? Is it wildly temperature sensitive? Can't be any worse the CFE223, which is about as close to the same burn rate, without actually being a clone.

Where's the love?

Edited: It?s getting old having the apostrophes and quotation marks replaced with ??? In my posts. What gives, how can I correct this?

I just picked up a can of it today. Will be testing it with 2460 on some 107s. Eventually, I'll make a thread for it too. Going to be a few weeks though, I'm a bit slow and need to pay attention to lots of things. That spells disaster for me usually.

Well, MidSouth Shooter Supply had free HazMat on the entire order this weekend with $135 or more of any Shooters World powder. So, I got a keg of Match Rifle and topped off my RL16 supply while I was at it. $13 shipping, free HazMat and no state tax, on 16 lbs of powder and serveral hundred bullets. I’m in!

Saw your A2460 post and am highly interested it that as well, with its seeemingly low temperature sensitivity.

AA2520 has been one of the most common, most popular powders for 6.5 Grendel from the start, with a ton of data on it.

It was one of the most common powders in the original Alexander Arms published data, Accurate Powders data, Hornady data, and data in the 6.5 Grendel Handbooks especially for 120-130gr cup and core bullets.

It's also one of the common ball powders for .223 Rem, .243 Winchester, and .308 Winchester.

And it was very hard to find for a long time.

SW Match is supposed to be Lovex's attempt at the Varget burn characteristics for the US market. I don't have any experience with it though. SW Tactical is supposed to be a H335 replacement too.

Here's a podcast of Ken Johnson, the importer, discussing it.

Right but we’re talking about “Shooters World Match Rifle” right, not AA2520?

Swapping load data between powders “can”be a little risky. At least for the uninitiated.

Having said that, have you used any SW Match Rifle, if so, what did you think? You can tell me the truth, you won’t hurt my feelings, I don’t have any!

SW is new enough, that not many of us have taken the initiative to be Guinea pigs. My experience with shooters world 4350 is that it is very nearly identical to H 4350. I had to up my charges by 3/10 of a grain. It seems to burn cleaner, and overall I was pleased with its performance.

I have no problem trusting shooters world load data. I would not super impose another powders data on top of it.

Wow, that encouraging, same temperature stability as H4350? That’s one of my most useful powders.

[Kswhitetails]

I cannot answer that. Unknown.

Sorry, I misunderstood your question in the OP. I have not used it.

I definitely don't recommend substituting another powder for another, and even work up loads again with the same powder if I switch kegs of the same powder.

Thanks.

One small correction, on the podcast he said SW “Precision” is their attempt at cloning Varget.

I haven't tried SW Match yet, but I love 2520.
I tried SW 4350 in Creedmoor last weekend. It looks very promising.

Here is a test I did of Match powder with a Hornady 123gr ELD-M bullet in a BCA 20" upper. I used a Magneto Speed V3 chrono mounted on a Wiser Precision picatinney mounted at the muzzle to get the MV and each shot was .2 of a grain apart. I have found that you can pick whichever node you like and it is accurate. I use Match in my 5.56-223Wylde also. This data was from a 65 degree day if I remember right. Its funny most of the other powders that I have tested in this manner have maybe 2-5 nodes but Match had several as you can see. I added the 2520 chart that I did with this upper just for comparison. The 2520 test was with a Nosler 123gr CC. I have never been able to get 2520 to shoot in this upper but have found good loads in my 223.

I should also add that at the bottom of the node where it goes to the lowest point I found that testing .1 grain on each side seems to be the best for accuracy of that node. I used a Hornady case with CCI450 primers. I seated the bullet at 2.245" and I haven't had a chance to really find the most accurate load or change the seating depth. I plan on doing that when the weather gets better.

In a side note since it has been mentioned in this thread, I did test SW Precision against H4350 in my Ruger PRS 6.5 Creedmoor and I got about 50 fps faster muzzle velocity from Precision. But I will have to say that that gun loves H4350. This was with a Hornady 140gr BTHP and Winchester LR primers with a Starline case with the necks turned and the bullet seated at 2.800'.

That’s awesome intel Jasper thanks. Looks like I’m going to have to try a few more now!
