Buffalo bore loads

[EdMc]

I've never seen one of the Nat Match Delta barrels so I can't say. The link blow shows a photo of a standard Delta barrel that you can compare. The Delta barrel is on the left..........notice almost 120 deg non support at the lower part of the case. Did you have any problems with the Buffalo Bore ammo you bought? Did you chrono any of those fired to compare?

I have two of the left barrel.  Looks like i have a good throwaway if I was a bad guy.  Haha.

Have not fired the buffalo bore yet.

I am a slow guy.  took me 22 years to pick this up after kings gun works redid it new for me in 1991.  Time to make it go again. 

Thanks guys.

Is this the same Bob as on KTMtalk? Welcome to the forum!

Those buffalo bore loads - if it was me, I'd fire the first few with the magazine removed from the gun. This way if you do get a case blowout, the gas can escape down the mag well.

Since you're a novice at this, you might seriously consider Accurate No.9 instead of Longshot, just because it's harder to get into trouble with #9. It's a low flash powder, and will deliver high velocity without as much pressure.

I better clarify something here - DO NOT just take someone's hot load data and try to duplicate it. You have to work up from a lower powder charge, carefully, and watch for pressure signs as you go. Be careful!

Yes thats me.  I worked up my 10 and 9 and 308 loads long ago. Thanks for the info.  So for less pressure and low flash the accurate #9 is better than the longshot?   Lots of great accuracy reports to the longshot.  How's the accurate for accuracy. 

My ten will hit a 12x12 plate at 100 yards from a bench.  Thinking about a compact 10mm and a s&w 1026

Hiya Bob. 

I can't say for sure if #9 has less flash than Longshot, but #9 is a very low flash powder. It generally produces very accurate loads in my guns. The downside is you use more powder per shot, so it's a little more expensive. A big advantage though is with most bullet weights, it's pretty much impossible to create a dangerous high pressure load, because you'll run out of powder space first. (Alliant 2400 is like this too, and very accurate, but gives low velocity and lots of flash.)

Edit - take a look at the powder flash pictures on this page, particularly images 5 and 6. http://jeffreybehr.zenfolio.com/p548446203 This doesn't show a huge flash with longshot, but definitely less with AA9.

Edit again - On second though, Flash Bob, maybe you should use Blue Dot, based on your screen name.

Like Yondering, I am a fan of AA#9 except for the cost per shot.  Meters extremely well, good velocity, good accuracy, low flash.  But, it works out to 35% more cost per shot.  I guess there is no free lunch.

Flash Bob, if you're assembling a personal-defense round, DO NOT use Blue Dot.  I've never used it personally, but based on comments from lots of people, BD has VERY high muzzle flash.

Again, based on powders I've tested, low-flash powders are HS-6, SR4756, A7, A9, and Universal.

It will be interesting to see if Buffalo Bore starts using BE-86 in the newer loadings, yes flash suppressed, meters well, clean burning and a little less powder for the yield...

Before the shortages they used Power Pistol powder in some loads...
