150 to 200 Yd. Whisper "Deer" bullet

[320pf]

Quarterbore just brought up a good point. Any bullet designed to work in the 30-30 will work for the 300-221 fireball out the distance (150-250 yrd) that were are discussing . So if you want to run 150 or 170 gr bullets use the ones that Sierra, Speer, Hornady etc... make for the 30-30

Thank you for the ballistics on the 125gr. bullets, they may penetrate sufficiently at 200 yards. However because my barrel has the 1:8 twist i am still thinking of a longer bullet that will take advantage of my twist, shoot more accurately and give me double lung penetration. Any expansion is yet to be determined (due to Whisper low velocities ) on the Hornady 178 gr. A MAX bullet, that i have been hearing about. I will attempt to attach a link that the manufacturer has to describe the terminal ballistics of these VERY THIN jacketed bullets. http://hornady.primediaoutdoors.com/HDstory10.html
What could be a worst case senario, penetration similar to the 240 gr. SMK ???? If you look at the cross sectional of the A MAX you will see a LONG polymer tip that goes deep into the bullet, that you would think should initiate some kind of expansion even at lower velocities. Opinions Please !

I use the 150 grain Hornady BTSP WITH 14.7 grains of h110, in a 18-inch encore barrel and I can shoot sub/moa at 150 yards. I also have been testing the barnes 150 grain triple shocks with 1 inch groups @ 150 yards, the only thing is I noticed you have to keep the bullet .060-075 off the lands.

Iwas messin around trying to find a 220 to 240grn bullet that will expand for my 300 whisper,I found my custom bullet for hunting.

16 inch tc 300 whisper 1in8 twist
sier 220gn RN at 1050 fps through my chroni

I took a 4x4x2 chunk of aluminum to my drill press,
took a 1/8 drill bit and drilled a hole all the way through then
chucked a 5/16 bit and drilled 1 inch deep dropped a 220gn bullet
in the hole and replaced the
5/16 bit with a 5/64 bit then drilled a hole in the bullet
a little less than a halve inch deep.
lost 5gn a bullet of weight.
the bullet was snug to get out, but the 1/8 inch hole under the jig
is used to tap the bullet out.
dont move your jig or your custom hollow points will all differ.
and set your deph for drilling.

I loaded up 10 rounds shot 3 through the chroni 1062 fps average,
shot 4 into the swimming pool (deep end) and had good expansion
ok lets go kill something.

went wild pig hunting 2nd day found 5 pigs at 125 yards took my shot a pig went down.
could not find bullet, exit wound hole the size of a golf ball.
3rd day found more pigs at 175 yards took my shot and a pig fell then got up and ran into the deep bushes just 20 ft away.
OH CHIT! I was thinking the bullet failed at tha yardage.
I found the pig just 10 feet into the bush, thank you hollow point.
the exit hole was still about the size of a golf ball.

Elk season last year was the test.
3rd day got my elk at 160 yards, bullet went all the way through
with a exit hole the size of a golf ball again.
The Elk only took 3 steps and fell over,double lung shot did the trick.
