Thread: Educate me on bushpigs

I did agree saying suppressors helped a bit. I find elec muffs very good, nothing is perfect though but I can celebrate differences from you.

Are you a tree stand hunter? I have been aware of some claims that modern electronics can filter out background noise and wind noise, but wearing muffs while actively hunting is just unpleasant.

Never claimed to be normal. As I got better I shot less, better shooting so fewer shots needed and got more selective, simply didnt feel any need to shoot just because I had the opportunity. If you shoot everything when you have the opportunity then that's another difference we can celebrate.

It was an obvious point that you seem intent on missing sort of like the noise issue being significantly lessened above. You ought to work out the difference between hunting and shooting.

I think you mean "Ballistics".
The best powder for velocity is dictated by the bullet /cartridge relationship irrelevant of barrel lenght. Standard pistol cartridges are small in case size, large in caliber and generally light for cal bullets. That is a recipe for fast powder. A slower powder would work better but you simply cant fit enough of it in the case. Put that pistol cal in a carbine and the recipe will remain the same. Take a larger cartridge say 7mm08, compare the published data for both pistol and rifle, you will find the powder recommendations will be around the same in burn rate. IIRC I think 2208 is very popular for both.
i could drag up the graphs of chamber pressure , bullet travel , area under curve etc Like I have in the past but I cant be arsed doing it all again so do some research and find out for yourself or cling to your misconception.

Well I just might have to... because I don't see anything other than talk about it, rather than some actual testing of the specific idea. Chamber size may have material effect on the suitability of powder selection in terms of how fast it is, but what I haven't seen is say a direct comparison between the same 22" barrel and 16" barrel with faster and slower powders and the same projectiles in order to determine what exactly happens... in say a 708/308 of the type of rifle that we are talking about here.

While pressure and burn can be understood simply enough in theory, the effect of faster burn/slower burn, on velocity and acceleration in longer and shorter barrels with those different powders, is probably best established by experiment.

What may have be happening locally of course is that when the active promoters of the short barrel suppressed rifle concepts are building these things, they also tend to drop projectile weights when chopping the barrels... that makes the actual effect somewhat murky...

However when differing powders have different outcomes in the same length barrel with the same projectiles loaded to the same max safe pressures, it would appear irrational to suggest that is not the case when barrel length is changed. Your argument of course is that performance remains constant whilst shortened relatively speaking. I haven't seen that being obvious in my playing around..

Of course I have never suggested that I can regain all of the speed lost simply by moving to a faster powder. Just that a faster powder might be more efficient at getting faster speeds in shorter barrels everything else being equal.

I would like to see a specific experiment.. if you are aware of one.. but relying on load data from inconsistent sources is hardly conclusive..
