300 whisper
 

Just registered 2 minutes ago. Want to hear about personal experiences with 125gr Balistic tips on big midwestern whitetails. I was just given a Bullberry 15" stainless bull barrel for my contender. Shot it for the third time yesterday. First time with fire formed brass and already shoots into an inch or less @ over 2200 fps with 18.5 gr of H-110. With Leupold scope set @ 8X and zeroed a little over 2" high @ 100 yds I can hit 12" steel gongs with every shot @ 256 steps, or approximately 240 yds, by holding just slightly above (approx. 2") the top of the gong. That speaks well of the cartridge and the barrel because I can't shoot pistols well...I'm a rifle guy. What I want to know about is field performance and range limitations of the round. One of my reloading books speaks of that bullet used in a 30/30 contender @ about 200 fps slower (don't know why it would be slower) and it was claimed it killed deer like lightning, but should not be used past 150 yds. The cartridge is a legal round for the entire firearm deer season now in Illinois, and we are sometimes presented with corn field and dry river bed shots in excess of 150 yds, and the development of sabot slugs and the H&R slug gun has taken SOME of my attention away from bow hunting since I can now know EXACTLY where my slug will hit out to 200 yds and what it will do when it gets there. So I'm wondering if the whisper could also fall into that category. The accuracy is obviously there, but what does the bullet do at those velocities? Don't baffle me with a bunch of energy table info please. I've looked it up, but I want to hear real life experiences. My arrow has virtually no energy but kills deer better than any pre-sabot slug ever did for me so I'm a little skeptical about immersing myself in all that energy data. I haven't looked all the way through the site yet so forgive me if the info is already here somewhere. Looking forward to hearing from you all, X

.300 Whisper SIG 551 SWAT
 

I am the proud owner of a converted SIG 551 SWAT.
Currently I am waiting for some more modifications to be able to use a silencer when I am on holliday with an aquaintance of mine in Switzerland.
In the Netherlands I am unfortunately not allowed to own a silencer.

The other modification I am waiting for is a different gas tube to be able to fire subsonic .300 Whisper ammo.

I will post a photo when my project is done.

Carbon Fiber AR-.300
 

I built a lightweight AR carbine using a carbon fiber/Aramid upper/lower reciever, CAR stock, 16" Wilson Arms 1/8 twist barrel, dot sight. Lots of fun, but no can in Iowa!

just got my 300 whisper
 

waiting on the suppressor to be approved...wow i cant wait..

I just finished putting my second 300-221 together. It all started when I wanted to build a rifle my daughter could shoot. I wanted something that would not have too much kick and that round in an AR sounded like a good combination. I started experimenting with loads for hunting, and found some good accurate loads with 125 gr ballistic tips and 19gr H110, 3/4 inch at a hundred. I really liked the low recoil and good accuracy. Some were asking about reports on how effective it is hunting deer, and I got to take it out last season deer hunting. It turned out my little girl was not ready to shoot yet, but I took the rifle out to test it out. I shot four deer including a 180 lb axis, and they all dropped where they were shot. The distances were 70 to 110 yards. Needless to say, I was impressed. I had been hunting with an '06 for years, and it was a nice change to kill a deer without blowing a big hole and ruining a lot of meat. I took the rifle out again for turkey season this year. The first day, I killed a piglet, and walking back to the camp saw some corsican sheep. I got a good rest and shot. The nice thing about the round is that with the low recoil, I kept sight of the sheep and saw it get hit. I checked the distance later and it was over 150 yards. It had walked about 20 feet and was dead from a heart shot when I got there. The next day, I shot another pig, about 70 lbs, and again it dropped where shot. It was nice that almost no meat was lost due to the shot. We do get some large pigs that show up on occasion, and it will be interesting to see how it performs on the larger animals.

Good report. Thanks.

I am building one on a Zastava Mini Mauser. MAB 1:8 26" barrell. No frills.

I hope that it will arrive next wednesday so I could bring it to the range on sunday.
I only have a few cases built from 223. Gosh.. hard work making these cases.. Wish I could buy them..

A friend and I built AR-15's in 300 whisper. Haven't had a chance to take either one to the range yet. Trying to decide how we want to build suppressors. Will most likely do them on form 1's or have a class II friend build them.

Need to see what loads each of them likes. One is a model 1 sales upper and the other is from J&T distributing. Both have Essential Arms lowers and DPMS lower parts kits.

From what I have been reading on here we need to get either an adjustable gas block, gas tube or move the gas block to the pistol position. We would like both guns to be able to use a suppressor and without along with both types of ammo subsonic and supersonic.
