220-240gn round nose performance on game?

[cr500]

Does anyone have any feed back on how 220-240 gn round nose bullets went on medium game at subsonic velocities? I,m interested in the 240gn Woodleigh round nose, but they will be realy tough ,suited to large game. Do the 220 Hornadys start to mushroom at this velocity? Do these longer pills tumble when they hit a medium sized animal? How about 240 Sierras? Do they tumble at all?

220 Hornady RN zips right through, very little damage. I've shot 8 deer with this at 1050fps and none have tumbled. However, if you know your dope and put it through the lungs/heart, they won't go far.

If you go for SMK's, they will deform and tumble causing a larger wound channel.

Its interesting that the SMKs end up better than the RNs, makes sense though, the round noses are meant to plow through a big elephant and such. I was hoping to use the SMKs for plinking, now I will be able to test them on game as well.

I have taken a number of deer with my 300 Whispers using the 240 SMK. Ranges varied from 20-70 yards. Entry wound is a small 30 cal hole exit wounds are large butcher knife like. Of the 6 deer I have shot all where body shots and none "walked" more than 50 yards. The 240 grainers out of my 16.25"TC Contender SSK/Shilen 1:8 twist tumble in flesh. The 240 grainers out of the 300 Wisconsin built on a CZ action with a Mike Rock 1:8 twist tumble in flesh.

The 240 grainer will tumble when shot in to a squirrel african heart style.

Well, I know someone who has been trying to get rid of a box off 240s for a while, I will snap them up. These 240gn pills will be longer than the case itself. It will be different to normal thought which is stay away from target bullets as they just puch through. I will be able to use the same bullets for target work as I use for goats,pigs etc.

I only use the 240 SMK for subsonic use... Most mass most energy and they tumble... it's a beautiful thing...

Gentlemen,

I got the bug to build a 300 Whisper for night hog hunting. We usually shoot everything at night and supressed, so our distances are usually under 200 yards. Most shots are under 100 yards.

I picked up a nice lower today and I have an upper. The barrel is being threaded to mate up with my supressor, etc. All should be complete by next weekend.

I have read several comments and blurbs about the .223 Rem vs. .221 Rem Fireball brass...so now I'm a bit concerned on which way to start. I did some checking with my suppliers and find all are "Out' of .221 brass. So, unless one of you fellow Whisper shooters can direct me to some pre-made Whisper or some .221 Fireball brass I guess I'll just have to form and make it from the .223 brass ? I would ask that if any of you have a accurate, pet, subsonic load for a 200 to 240 grain HPBT to share it with me please.

Thanks in Advance.

for brass I got no trouble with the 223 brass because my reamer is 30-221 fireball. I got plenty of expansion to use .223 brass.
If your reamer is a .300 Whisper reamer. You (might) be able to use 223 brass maybe. After you Ream your Chamber. 1st, Mic. your reamer at the neck OD. Then take your .223 formed brass and (bullet) load one or two and Mic. the necks of the load. To see if your Neck has enough space to expand & contract in size when fired.
If you don't have a few thousandths tolerance for Neck expansion on .223 brass. You Will have to use 221 brass. besause the necks will be thinner with 221 and give you more room to play with.
It all depends on the Reamer. Plus maybe even how many times the Reamer has been sharpened. Because the reamers get smaller as the # of Reams go on using it.

for my only load so far . I use 9.2 grns. #9 powder with 220 grain Hornady RN-flat-base bullets. (but) my barrel is 8-twist, 5R @ 17", in length. doing right around 999-1020 FPS. Vel. Chronyed @ 34 Deg. F. temp.
I am staying a little low on the Vel. for now. To see how much Powder-Temp. fluctuation rise, I am going to have when the Summer comes and the ambient Temp goes up and gets hotter.
.

OK for the Thread Post topic at hand:
Has anybody got any actually tried just taking the Round-Nose soft points with the flat base. Putting them on the Lathe and just making a SWEET FAT HP in them ???
(personally) I have great result with a modified HP on my suppressed .22 rimfire rounds hunting. I get HUGE expansion @ subsonic velocity with them.While still maintaining Match Accuracy.
There is a reason that Match subsonic .22 bullets have been round nose and flat or a concave base for decades of winning competition shooting. That is because that bullet shape is conducive to the flow-field of air movement that is moving around the bullet in flight @ low speed velocities.
So for, - Subsonic Velocity Only - I am going to have to say. I believe that they are gong to Out Perform any Speer-Point Boat-Tail HP bullet. But the problem is that there is going to be No Expansion at Subsonic Val. unless you can put a BIG HP on the end of that Round Nose. And a Big HP on a 200-220 grain on any expansion is going to pound with more enegy with Hunting Game.
Even the HP subsonic/Match will Not expand for hunting but little to None with the little tiny factory HP hole. The Holes are made/designed for Hyper Vel. expansion and only there for accuracy sake. I have even taken a few coyote with the modefied .22 even though it is going subsonic. The bullet Expansion makes all the differance in the world.

Ok here is Pic. of my (wet) Phone Book tests using my Modified HP's Subsonic rimfire .22
one pic. side by side. factory HP & Modified HP
then pic. of expansion SIZE @ subsonic on Wet Phone Books

The big round nose soft points will be perfect for this. I will take some and start screwing around with them pretty quick. But I am 99.9 % positive the results will be positive for the expansion needed for 'Subsonic Hunting'.

My biggest problem is not modefying or shooting the bullets. It is trying to stop the 400+ lb/ft. energy to make documentation of the improvments,
WAS Easy with the .22 subsonic HP. It only got 60-80 lb/ft energy @ 100 yrd. . You just stack a few wet, water soked Phone Books together and you got them.
I might have to go on the hunt for some Road-kill Deer, ..:grin: . around local to hang and shoot and then autopsy and get some Pics. it will Not be that easy to stop with all that energy.
For me to build a Balistic Gel-Tank is far to much time and effort to prove something that is only obviously going to expand Big. So the road kill might be my only option.

You guys are missing the point.

Forget expansion for sub loads on large animals. That's not going to happen with current large caliber technology; nor should it. Since you are dealing with low velocity/low energy loads,; if you design a super soft, expanding bullet it's not likely to exit and only create a caliber sized entrance hole that would likely be sealed with fat or other tissue not leaving a blood trail. Subs loads drop quickly and the difference of 10 yards beyond the first 100 can mean a drop of 2-3". The purpose of the SMKs is to have a high BC leading to flatter trajectory which gives you a decreased drop at longer distances and increasing your success rates at hitting a vital organ. Furthermore, while you can't get away from the small entrance hole, the HPBT's quickly deform and tumble in the body cavity exiting with a large, knife like wound, leaving a clean kill (assumung you didn't screw up the shot) and leave a blood trail.

If you want to shoot varmints with an expanding sub load you shouldn't have any problems and you are typically not worried about tracking/blood trails.

Hi CR500,
I have used the Hornady 220gn RN for over 18 months now on goats in the central west slopes of NSW and they are excellent. I have also used the Sierra 220gn MK as well and are just as effective at subsonic speeds. The SMK do tend to tumble more on contact I have found than the RN but both do the job at ranges out to around the 100m. Shane
