Tried Hawk Bullets?

[pmc]

Richard, good to see you post over here. I am liking the idea of a coyote killer. With this round the higher the BC the better as it starts out so slow. I am willing to do the tests on whatever you work up.

Yes it's good to have you on board Richard! All my whisper shooting to date had been with 240gr Matchkings at subsonic speeds so would love to get my hands on some similar weight bullets that EXPAND at that speed. That would simply be the ducks nuts and would get an order of 500 bullets straight away.
Thanks for taking up the challenge PMC - I will eagerly await results of your trials. Its good to see someone with your experience and back to basics testing to try these things out.

It is great to see you here! Bullets that perform well with the 300 Whisper would also be useful for the single shot pistols like the T/C Contender in 30/30 or even 7.62x39 with a .308 bore...

could any of you guys give some ideas of velocity expected at extended ranges with this cartridge??? This will help to decide on the meplat opening, the tighter the better as far as bc is concerned,but a tight meplat is not the thing you want for expansion.
What actions are most of you using to build these rifles on,what barrel length??? Sorry forall the questions,but the more and better I know,the better grasp I will get for whats needed.
Thank-you all for the warm welcome

Richard here is what I am shooting. Rem 700 with an 18" Barrel. You will find quite a few guys on here with AR-15's in various lengths.

My data for the 240 gr SMK is as follows.
Muzzle Velocity - 1060 fps
100 yard Velocity (calculated) - 1027 fps
200 yard Velocity (calculated) - 998 fps

I'm shooting a Thompson Contender carbine with 18 1/2" 1-8 twist barrel so I can use the heavy 240gr MK at 1050 fps from my barrel. Most whisper users have 1-8 twist barrels to utlilise the heaviest bullets possible for as much energy transfer as possible at subsonic speeds. There are some whisper users with a slower 1-10 twist rate that will only stabilise 220gr Roudnose bullets at subsonic speeds.
BC at these speeds is really erelevent.........what we need is expansion....not the pencil stab wounds that we get with bullets not expanding at subsonic speeds.

Thanks guys,thats the info I was looking for.Now when you say we need expansion,are you saying you want a nice mushroom,or total blowup into lead dust and jacket fragments,there is a huge differance between the two from my perspective. Now,a real stupid question, is the 200 yd distance about tops or are you looking @300.400 etc where the velocity gets even slower.A bullet that will expand @950 fps may have some isssue's expanding @500 fps. Remember I know nothing of this cartridge and you fine fine folks will have to kinda hold my hand for a bit ,untill I get my legs under me LOL
thanks

Personally I am not looking for a 300 or 400 yard shot on game. I limit my shots to 100 yds or less, but part of that is because I live in Middle TN. Lots of woodlots & small fields. I really have to work to get a shot longer than 200 yards.

As far as expansion a nice mushroom would do nicely for deer loads. For coyotes loads I am thinking a frangible bullet would be great.

For me hunting ranges can range from 25yds all the way out to 200yds where I draw the line at using sub loads on game. Once past 100yds bullet drop is a real issue so a range finder is a must!
A bullet that would still give a nice Mushroom at 200yds would be excellent.

I still can't believe no body else is posting here for recommendations to give richard some help on bullet design!!!! Come on someone is here trying to help..
I'm sure plenty of people have read these posts!

I shipped the bullets today.I would think about 12 working days BUT sometimes I think canada post uses a horse and a fat clydsdale at that!!!!!! This really doesn't make sense to me,but to deliver to FortShaw Montana usually takes 18 days,I can drive there in 10 hours!!! I can ship to texas faster. Thanks for the info and imput on the bullets,
