SHOW THEM THIS WHEN THEY ASK "WHY 10MM?"

[Geeman]

I hope that little flash isn't impressive to you. Want impressive? Come to my house and I'll put you on a muzzle blast from hell. Try a 30-30 Contender with 35.0grs H335 under a 110gr carbine bullet. Muzzle flash is about 12 foot out and about 8 feet round. The load is surprising accurate too. I normally take the gun with me to public ranges in case I end up next to a city moron. I take one step back and touch a round off. It's like getting slapped with a 2x 4 if you're within 10 feet of me. At night, you'll be blinded after shooting the gun for about 30 minutes. It's about as bright as a welder and will light up targets at 100 meters. The entire setup for that load is loaded just for the muzzle flash. It's impressive but so is the 3oz SSK trigger in it.

Have not shot the 416 Rigby Encore at night yet.  95g of reloder 17 pushing a 350g soft point.  Out of respect for other shooters, it usually doesn't come out unless the range is empty.  Keep your mouth shut, of your ears will be ringing, even with plugs and muffs.  That thing has a concussion!!!  4600 ft*lb out of a pistol.

You like it flashy?  Try Power Pistol.  This load is about two grains below top end, and BTW, it's not a 10mm load.............it's a 40!



4" 357 Magnum from behind......



Mild 45-70 load.......



450 BM, 20" barrel.......

AT LEAST a flash from a firearm is not like black clouds from a diesel truck, all that unburnt fuel is totally wasted. Adding extra powder is maintaining pressure after the initial spike, and has a nominal effect.

Call me novice but if the burning powder is still pushing the bullet after it leaves the barrel, would it not cause destabilization?  Once bullet exits, there is no guarantee the pressure is even and pushing in the desired direction.  What am I missing?

This is why a good barrel crown is so important.  If the bullet leaves the barrel with inconsistent pressures around its base, it's going to be destabilized.   The pressure wave as the bullet exits is not likely to ruin the bullet's rotation or kick it sideways as long as the muzzle crown is concentric and even.  Put a scratch in the lands of grooves near the muzzle and things change.  I once had a Marlin 30-30 that had been dropped on the muzzle, the damage was hard to see with the naked eye but the results on target were really obvious.  I had a gunsmith remove an inch of barrel and cut a target crown, and it went from shooting 10" groups at 50 yards to cloverleafs at 100.  Cost me all of $30, as I recall.
