Looked like I'd been shooting black powder. Took me about an hour to clean it up. No leading, but it was really dirty powder, and I wasn't expecting it to shoot as badly as it did, accuracy wise. At least I didn't get stupid and do any sight adjustments based on it.I thought this part was interesting as I have never seen any smokless powder leave reside like you described so I looked at Underwood's website and saw this:Looked like I'd been shooting black powder.
I have no idea what 'flash suppressed powder' is but I cannot believe whatever it is burns completely if it is reducing the flash as they advertise and therefore leaving the residue as you describe.As with all of Underwood Ammo™ rounds, we utilize flash suppressed powder so that your vision will not be compromised if it becomes necessary to use your firearm in low light.
This is quite high and unless they chrono'd it out of a rifle I cannot believe they are getting this high of velocity.Muzzle Velocity: 1560 fps
I've been using Underwood for about 10 years. It's a clean, fast burning burning powder that is extensively used in pistol ammo, and had nothing to do with the mess made by the GA SWC. I don't know the exact chemical composition of it, however. As for MV, their listed MV is accurate out of my 6.5" Blackhawk.Mistered wrote:I thought this part was interesting as I have never seen any smokless powder leave reside like you described so I looked at Underwood's website and saw this:Looked like I'd been shooting black powder.I have no idea what 'flash suppressed powder' is but I cannot believe whatever it is burns completely if it is reducing the flash as they advertise and therefore leaving the residue as you describe.As with all of Underwood Ammo™ rounds, we utilize flash suppressed powder so that your vision will not be compromised if it becomes necessary to use your firearm in low light.
I also have a REAL hard time with this:This is quite high and unless they chrono'd it out of a rifle I cannot believe they are getting this high of velocity.Muzzle Velocity: 1560 fps
My reloading manuals do not show a velocity this high on any loads out of a handgun.
I overlooked this part - (it's early here in Oregon!) so retract everything I said except the part about he MV.and had nothing to do with the mess made by the GA SWC.
I guess I don't know what to tell you about your doubts concerning MV of the Underwood, other than to say that when I first considered using it I also had some doubts, but they had good reviews, and I talked with the owner also. Bought a box to try it out. Their test gun was also a 6.5" Blackhawk, and when I chronoed it in mine it was consistently within 10fps of their stated mv (actually a bit faster) This was several years ago, when the price was about 65cents/round so I ended up buying several hundred rounds, and haven't looked back.Mistered wrote:I overlooked this part - (it's early here in Oregon!) so retract everything I said except the part about he MV.and had nothing to do with the mess made by the GA SWC.
Still seems pretty high.
It's excellent ammo. You should try it if you shoot .41, or any of their other calibers of your choice. GunnyGene wrote:...This was several years ago, when the price was about 65cents/round so I ended up buying several hundred rounds, and haven't looked back.
Perhaps with the GA ammo, but as I said earlier, I've never had a problem with the Underwood. Not years ago and not in the last 2 weeks. Nor do I leave any ammo in vehicles or some other place which is subject to extremes of heat and humidity.Mags wrote:Don't know if this is accurate or not, but an internet search find indicates that "Ammunition doesn't expire, but the gunpowder looses potency over time." Maybe why the dirty firing. Also found heat and humidity accelerate loss of potency. An example given was leaving ammo in a hot and/or humid car. Another find, expected 'good' shelf life of 10 years.GunnyGene wrote:...This was several years ago, when the price was about 65cents/round so I ended up buying several hundred rounds, and haven't looked back.

We can accept that.

Be mindful of that in what you share and forgiving of the responses.I know that, which is why I tried to be courteous and gentle with that comment.CT_Shooter wrote:These folks are not trying to challenge your experience or knowledge.

Never used Ballistol, so can't comment on that, and don't do much shotgunning. That said, I've used Hoppes solvent for decades and it works as well as anything else unless you have excessive lead or copper fouling, in which case a quality solvent specific to that problem should be used with a non-metallic brush. I use Blue Wonder, but only when the fouling is severe enough to affect accuracy and I don't overdo it. Bore cleaning should be tied to accuracy degradation - see this: https://www.youtube.com/playlist?list=P ... vDCIcEPxUn . Although Rex is specific to ELR rifles, the general principle applies across the board. Scroll down on the playlist to around Parts 37 - 41 or so. In particular part 41. If all you need to do is wipe the powder residue out then a dry patch is all that's needed. Too aggressive cleaning is just as bad as not enough.JEBar wrote:GunnyGene
thanks for mentioning Georgia Arms Ammo .... I'd never heard of them so I did a bit of research .... from what I could tell, they seem to be a well known outfit .... in recent times I've noted that the powder being used in Winchester Super Target 2.75" 12-Gauge Shotshells we use for trap shooting seems to leave our shotguns really dirty .... in trying to figure out why, I considered the fact that for the last couple of years we have used Ballistol to clean and lub our firearms .... it does a great job and I have no interest in using anything else .... that said I can't help but wonder if some cleaning liquids trap more residue than others .... do you have any thoughts in this area
Neither do I. Nothing changed between the shots with the Underwood and those with the SWC. Absolutely nothing - both were shot in the same session at the same range and the same POA. The only difference was the ammo itself. Which is why I was so surprised. I did expect some minor difference in POI, but nothing like I experienced. Oh, well. In the big picture it was a one-time minor irritation and won't be repeated. Life goes on.JEBar wrote: that doesn't seem to be the case so I have no clue why there has been such a big change in residue
Ok - you didn’t mention in your first post you chronoed them but if you did and that’s what the MV is then all the better!and when I chronoed it in mine it was consistently within 10fps of their stated mv (actually a bit faster)
The Underwood was a lot tighter - about 2 1/2". SWC looked like a 00 buck pattern. The only thing it had going for it was a soft recoil.JEBar wrote:just curious, I can understand the point of impact changing from one brand to another .... how well did they group ..
Sorry 'bout that. I tend to assume (yeah I know) that folks who experiment with unfamiliar ammo, or reload, do that as a matter of course. I don't reload, but I have a couple friends who are constantly working up different loads and have chrono's they let me borrow occasionally.Mistered wrote:Ok - you didn’t mention in your first post you chronoed them but if you did and that’s what the MV is then all the better!and when I chronoed it in mine it was consistently within 10fps of their stated mv (actually a bit faster)
You would be surprised at the number of reloaders who do NOT have a chrono - me for one.Sorry 'bout that. I tend to assume (yeah I know) that folks who experiment with unfamiliar ammo, or reload, do that as a matter of course.
