Since you are using a 308 bore, would this bullet not work as well in a 30-30 Contender?

MECH8: I SAW ON THE SPEER SITE WHERE YOU HAD TRIED THEIR .308 150gr BLK GOLD DOT IN A 300 BLACKOUT, BY ANY CHANCE WOULD THE 123gr .310 GD WORK IN A CONTENDER IN 300 BLACLOUT OR 30-30?

I have no doubt that the 123gr Speer Gold Dot .310 diameter would work in the 300 Blackout or 30-30 Win chambered in a Contender. I don't believe the extra .002 inch in diameter would create excessive pressure issues, since the lead alloy core on these bullets is relatively soft in order to provide expansion at the lower velocities produced by the 7.62x39. I could see an issue if you were trying to push a brass or bronze solid down a bore that is .002 smaller than the bullet, but that is not the case. Of course I will throw in the normal disclaimer about start low and work up slowly while monitoring pressure signs. About the only issue I could foresee is in the event someone has a tight chamber neck and the extra .002 would cause the case to not enter the chamber all the way, or possibly not have enough clearance to expand and release the bullet upon firing. Unless your barrel has a tight chamber, I don't think there will be an issue. These are just my opinions based on what I have done to date.

Here is some work I did with my Ruger American Ranch bolt gun in 300 Blackout using the 150gr Speer .308 Blackout bullet. I'm just throwing it out there for anyone that might be interested. I was originally going to use the 150gr bullet in my 32-20 Contender, but figured the case wouldn't hold enough powder to provide enough velocity for expansion. I'm not certain of that any more though, since someone over on the 300 Blackout forum tested them down to 1400 fps impact velocity and they still showed signs of expanding. Might be worth trying, I'm still up in the air.


300 Blackout with 150gr Speer .308 Blackout bullet, and expanded bullet tested at 100 yards. Muzzle velocity approx 2100 fps.


A little hard to read, but the best load was 23.0gr AA1680 ignited by a CCI450 primer. Velocity 2114fps, group size .714 at 100 yards.


Comparison of 300 Blackout with 150 grain on left, 32-20 with 123 grain on right.

The rifle has a 16 inch barrel, so velocities in Contender barrels shouldn't drop too much.

The 32-20 is just a cute, neat, easy to shoot, cheap to feed cartridge in the Contender. I had hoped that it was capable of taking deer and other medium game at short range, and it proved that it could, although one test is not enough to declare it so. More testing is needed!

Nice shooting and a very informative post.

Great performance out of that round on that deer.

Good job! Looks like the 32 caliber cartridges are pretty effective with proper shot placement.

I have used my Contender carbine in .32-20 on several deer, but with a considerably different load philosophy. With its 1:10?? twist the 22? barrel can stabilize heavy bullets, so I took the idea of numerous handgun hunters who shoot the .300 Whisper (BO, WTF, etc.) by using subsonic loads. I load the Sierra 220 RN bullet to 1100 fps for an accurate, quiet, low recoil but deadly deer killer.

The long Sierra is stable in flight but once it hits flesh it tumbles immediately, producing very effective wounds. One penetrated stem to stern on a small buck with immediate knock down. On lung shots it takes a second or so, but kills very well. I would use the longer 220 HPBT but that bullet requires a 1:8? twist.

Regardless, thousands of deer have been killed with sub-sonic .308 bullets. Just a different way to skin the cat.

I've been preaching the Sierra 220 gr. RN in the .300 Whisper for a few decades. Tumbles great, creates decent internal damage, and very accurate out to 300 yds. Works great on deer, groundhogs, turkeys.
The 220 Sierra HPBT does NOT work , at least, in the Whisper. Not quite long enough to tumble. Get pencil tip size holes all the way through a deer. The few I shot with it took 4-5 minutes for them to die. They gave absolutely no reaction to the shot. I thought I missed them.
The 240/250 HPBT, though, performs really good in the Whisper (that's what JD originally used when he developed the Whisper). Jagged exits, little less internal damage than the 220, excellent penetration, and accurate out to 300 yds.
I haven't killed 1000 deer with the Whisper, but the 115 I've done have given me a bunch of experience with this great round.
You .32-20 guys might want to consider Lehigh subsonics. They out perform the 220 & 240 Sierras.

SORT OF A DIGRESSION, BUT ALONG THE SAME LINE, ON MY FIRST AFRICAN SAFARI IN 1988 I USED 300 gr HORNADY RN FMJ's IN A 375 JDJ ON PLAINS GAME. I DID NOT DO ANY AUTOPSIES, BUT TO THIS DAY I STILL THINK ABOUT HOW WELL THEY KILLED. I ALWAYS "THOUGHT" THAT WHAT MADE THEM WORK SO WELL WAS THEIR LENGTH BUT I HAD NO IDEA WHY. MAYBE IT WAS THE SAME EFFECT AS WITH THE 220 SIERRA RN IN THE WHISPER?

Doc, I assume that your Whisper has a 1:8? barrel. I suspect that the 220 HPBT would be marginally stable in the 1:10? twist of many .32-20s, your thoughts?

Carpe, oddly enough, I never asked JD what twist I had. He told me initially to use 240/250 HPBTs. They worked, then he encouraged me to use/test other bullets. My SSK barrel shoots everything great from the 240/250 HPBTs to the 170/186 gr. Lehigh fracturing HPs. I also tested a bunch of other bullets for Lehigh with different weights/shapes that shot great, but performed poorly.
Recently a friend gave me some Horn. 200 gr. RNs with a flex tip or whatever. They shot about a foot higher than all my other loads, so I'll not be testing them.
The 220 HPBTs shot well in my gun. The first 2 deer I shot with them at 200 yds. kept on feeding for 4-5 minutes then dropped. They hit exactly where I aimed. I, too assume my barrel is a 1:8.
I don't know if this will translate to the .32-20 sub, but my bullet preference for the Whisper is:
1) 220 Sier. RN (cheap, accurate, deadly)
2) 186 Lehigh fracturing HP (expensive, extremely deadly- 80-90% instant drops/kills)
3) 250 Sierra HPBT Match- not made, but longer than 240, more unstable, tumbles great, kills very well (JD gave me a bunch).
I use these 3 about all the time.
