cor-lokt ultra bullets
« Reply #30 on: May 13, 2005, 04:07:14 PM »
have a 300remsaum- in the 673 guide gun - without reloading ammo selection is limited. tried a box of the 150gr corelokt ultras. just about every 3 shot group was touching. I have never had this kind of accuracy with a factory bullet before. Have shot several deer and am also pleased with their killing performance.

Used to shoot BT all the time and they are fine up to around 2700fps. IMO.anything faster and the bullet comes apart way to much. Have started shooting the swift scirocco in my 7ultra mag and am very pleased with them (around 3550fps). Me, I like an exit wound even if it means tracking and few yards more. A animal that don't bleed is often hard to find if it only runs 25 yards or so.
 
Just got a 270wsm and will try the fed 140gr accubond and the fed 130 barnes trip shock. if no luck in them factory loads will try the sciroccos and trip shocks in handloads.

Well, my experience is only with whitetails here in Alabama. I don't know exactly how many I have killed in my life but it's gotta be close to 100. For a big chunk of my hunting life (age 18 to 30) I used a 30-06 and 150 grain core-lokts. I missed deer and I made a few bad hits but I never lost a deer due to this bullet. Out of the deer I killed in that time (at least 5 a year) I only recovered two core-lokts that did not exit and they were just under the skin on the offside after severely angled shots.

I think we hunters sometimes create our own bullet problems. For instance the average shot distance on deer in the area I hunt is probably less than 100 yards yet many feel compelled to go buy these super duper ultra mags with a muzzle velocity of 3400 fps. And hey, it's their money. If that's what puts lead in their pencil God bless em. The problem is then that they go out with this new scud missile launcher and use a standard cup and core bullet like core-lokts. They lower the boom on a deer 50 yards away, smack him in the shoulder and get core jacket separation due to an impact speed of around 3300 fps. Then they forever loudly proclaim that core-lokts suck. So they move up to premium ammo. The problem with some of it (besides the cost) is that it's so toughly constructed that a ribcage shot that doesn't impact much bone may not cause it to expand a lot.

A series of problems caused IMHO not by bullets but by not matching the gun to the hunting situation at hand. If the shot distances will most likely be about 0 to 150 yards as it is on my land then you can take a rifle caliber with a muzzle velocity of about 2800 fps and use just about any standard soft lead tip bullet you want and it will kill whitetails just as consistently as any premium bullet on earth. In fact I killed a 225 lb 7 point (the biggest bodied deer I ever killed) with a 100 grain core-lokt out of a 243. Wanna see the bullet? Me too but it went out the other side of him still hauling @$$.

I generally shoot whichever SP bullet my rifles group best and right now thats Hornady SP and Winchester Power Points but if core-lokts happened to be what one of my rifles liked best I wouldn't hesitate to use them again.

I guess I will pitch another log on the fire with my core-lokt story.  First experience, I had nice heavy(183 pound dressed) 8 point run underneath my treestand and stop.  I shot him in the back of the neck with a 7mm magnum, 140 grain core-lokt.  Yep dropped him in his tracks, but I found dozens if not hundred pieces of lead shrap metal through out the body.  Given the shot was about 12-15 feet with a magnum, I guess that makes sense.  My second experience was not that great.  The following year, same tree, rifle, and box of ammo, I shot a doe at 40 yards.  At the shot, she finched and ran off.  My dad with his 22/250 shot her in the neck about 80 yards down in a draw and dropped her.  After I went down there and told dad what happened we examined the doe.  Yep, My shot was right though the boiler room.  The entrance and exit wound were the size of a PENCIL.  Very little damage to any organs where the bullet past through.   I know other guys have had great luck with these.  For me, there is better things for the job.  I like Hornady SST.  I have used these in 30.06, 300 Win mag, 300 Saum, 243, and 270.  I have NEVER had a deer hit GOOD with these take more than two steps.  With that and dollar you can a good cup of coffee.

I bought a box of the 168 grain Remington factory-loaded Ultra Core-Lokt ammo and tried it in a couple of my .30/06 rifles at 100 yards.  It didn't shoot anywhere near as accurately as the plain 165 Core-Lokt ammo.  I have not tried it on any game animals yet and probably won't since the plain Core-Lokts, both 165 and 180 grain, shoot better in my rifles.

You can think it and I am skeptical myself, but I am not so willing to believe that the new CORE-LOKT ULTRA Bonded is inferior to the tried and true Partition until I have seen first hand what the ULTRA is all about.


  The new Cor-lok may be better than the old one, but it sure won't be up to Nosler partition standards!!!

  I use to design, build and sell bonded core bullets BEFORE everyone else was doing it!!!  My experence is that "guilding metal" just doesn't make the best jacket material for bonded bullets.  The 5% zink just makes it too brittle.

  Guys that say here that they have shot a hundred deer and bla bla bla.....  have a  decent amount of deer experence, but once you change animials, everything else changes too!

  I like to have one load for each of my guns, so i tend to put something in it that i know will work on EVERYTHING i will be hunting, from deer to moose ect...  It better work on quartering shots too!!

  I expect my bullets to expand "fast", and then penetrate deep going on through!!  If it sheds it's core or doesn't go on through i call it a failure!  NP's are the only bullet that can do this at both high and low speeds!!

  Haveing said that, i pretty much use NP's for all of my hunting needs!

Bullet Choice

O.K., here goes some gasoline on the fire!!!

Always the odd man out, you are going to think my choices odd.  But here goes.

Sierra Gamekings or Hornady SST's in my .25-06 BTSP.  7mmWSM gets a 160gr. Sierra HPBT or BTSP, depending if it's Bull or Cow I'm after.    30-06 gets the 165gr. Hndy BTSP, SST, or Interbond (a thought, but haven't tried them yet).    For plinkers, I use Winchester Power Points.  Game of choice is either Mule deer or Elk.  

Why don't I use Nosler's?  Physics. 1) I want all the kinetic energy in that bulllet to be deposited into the animal.  A fast to medium opening bullet, REGARDLESS OF DESIGN, will provide that.  An exit wound means that the bullet didn't do it's job of expending the last of it's energy into the vital organs.  2)  I have yet to work up an ECONOMICAL load with anything of Noslers that I can maintain a 3/4" group @ 100Yds with.  For me it's got to be that tight.  Because as you extend your distance, the minute of angle that your bullet is out of the group is magnified on a logarythmic scale, typically of e to the 1.5 power per 100 yards.  (Just my experience, you can check your own results).  

That means that the farther I am away, my odds of missing are increasing.  Sierras and Hornadys deliver that margin, and Noslers don't.  That partition at the bottom of the bullet isn't going to matter a whit if I can't deliver a payload on target.   And like everyone hear seems to agree upon, shot placement is critical.  

Just my $.02 worth.  
 
Y'all have a good day, hear?

  Here's why i WANT to see an exit wound in the animials i harvest.

  I harvested this "meat buck" last fall, i found him laying on the "entrance" side, and i did nothing but take a pict. turn him over and take another pict..

  "If" the animial runs into THICK cover, do you want some "tracking" blood?????????????????

  The pictures tell the the story!!!

  I have no idea why you can't get accuracy out of NP's???  In over 35 years of reloading i've yet to NOT beable to get a hunting gun to shoot "very good to excelent" groups with NP's!!!

  Groups like the below are not "uncommon"!!!  Keep in mind this is a 7 pound hunting gun with a 4x scope!!

Hey Drilling Man!!

Drilling Man,

Those are good groups!!!  The kind of consistancy that I have looked for out of Noslers.

I don't know why I haven't been able to derive the same out of my loads for Noslers.  However, I stressed economical since Noslers cost generally twice as much for 100 rounds.  That makes it tougher for me to justify the cost  - hey, I'm a grad student whose wife is expecting our first-born - of testing with the Noslers.  I know that the more inexpensive Sierras and Hornadys will work out just fine.

You also make a good point about the blood trail.  My goal though, is for them to crumple up where they are hit and not have to track - same as everyone else.  I can only hope that there is a blood trail if needed.

Anyway, there is a Combined Technology Partition Gold (Moly Free) that I want to try in my 7mm WSM.  Maybe one of these days...I'll post the results if I ever get them tested.

See ya,

Matt  :D


P.S.  My apologies for the CAPS earlier.  I just now figured out how to get this thing to italicize for emphasis.  I wasn't trying to shout.

If I had to select ONE bullet for everything, I too would choose the Nosler Partition.   Next in line would be the AccuBond.

I've been very impressed with Nosler's line-up because the quality of the bullet provides the results they conservatively claim.
45 ACP 230-gr. Double Tap Gold Dot = 1,010 fps / 15.3" & .95"    :D

Aim for the Triangle Area between armpits & throat.

I shoot Hornady, Serria, Speer, And Nosler Partitions. Have shot a few of Remington bullets but not at game. I am trying to find out witch bullets can handle 3000 fps and higher. :D

I ordered some so I can try them in my 300 win mag. I didn't see where they were listed for the 338. :D
