For the guys asking about sub-sonic reloads.....

Heres my currrent setup. FNSPR A3G (tan now) 24" 1-12. Shooting at 185 yards at an old muffler about 6x35. The report happens pretty fast actually for being alomst 200 yards out. But its quiet with the Coastal can.

Thank you and thank you.

Its pretty hard to shoot whilst holding a camera.
WCC brass, TB @ 8.8, 150gr. Winchester soft point round nose flat base 30-30 boolits and Win LR primers. Runs fine at 20' elevation, 35-70 deg. Remember, the SPR sports a 24" tube, maybe thats why theyre flyin straight. Theyre hitting on the nose at 185 yds. I went down and picked up about 5 nicely mushroomed projectiles from around the target, and numerous deformed pieces of 30cal lead and mangled copper jackets as well.

Ive loaded some 175 SMKs. haven tested them past 50 yards but theyre good at that range. Ive loaded quite a bit of subs and never had a baffle strike.
Most reading that Ive done says that boat-tailed rounds dont stablize when subsonic so Im guessing that the flat base has alot to do with it. Also, a soft point bullet has more mass at the nose than a hollow point or FMJ. Lead is denser than copper, so the more weight forward the better. In the case of FMJ bullets, if you replace the lighter copper with heavier lead that gives more weight "per capita" at the nose. More forward mass means it will fly more like a dart, pointy end forward.

These are just my thoughts. But it works for me.

If you look closely at the beginning of the video you can get a good shot at the projectile when I load the gun.
just an update.

heres some more info......a while back I loaded up some 175smks and here was the result......

9.0 gr was supersonic most of the time. These were shot into two, back to back, one gallon water jugs with a plywood back stop and we recovered as much of each round as possible. The last round fired, 5.5 gr of TB, didnt even make it through the second jug of water so I stopped testing there.

Remember, these were 175gr SMKs. A 30/30 soft point 150 gr would fly a little faster and mushroom alot better making it a great small game round in my book. Good for hogs, coyote and the occasional tresspasser. All of these except the 5.5gr went through two gallon jugs of water and stopped in a piece of 3/4 plywood, so an easy 18" of penetration with a nice mushroom.

I just noticed that after posting the picture for some reason it chopped off a few inches of the right side. There was another round pictured there that you cant see. It was the 8.8gr round. Anyway, it was near perfect mushroom very similar to the 8.0 gr round pictured on the far right.
