When did the old Corelokt PSP/Interlock/Super-X style bullets quit being effective?

Friend replaced his near 20 year old silver Toyota hatchback with a gr corolla. Nothing wrong with the old one, still ran good with no problems and good mpg. New car technically functions the same, and considering the cost the old one was arguably the better value. But let the turbo loose on the GR, and the commute just got more fun.

Cup and core bullets worked/work fine, long range hunting is more on the fringe. Kinda the rifle hunting aficionados, b.c. and downrange performance matter to us enough to warrant cost.
 
Sooo, my $.02. The boolits you speak of have always been good, as several have mentioned. I believe you are in great shape to use them at the velocities and distances you have mentioned in your original post. Get you some!

I got away from them because factory ammunition, especially the cheaper stuff, but in reality all of it, never gave me the accuracy I was after. The blue box federal ammunition was the worst in my 243 and 30-06. 3" to 4" groups at 100 yards was downright infuriating!

I have hand loadeded since I was in 8th grade (thanks dad!!!) As such, I cheaper opted for better boolits. Nosler BTs and Accubonds, Berger, Amax, BTHP's, and now the A-tips and ELD lineups. Why not?

I still load some spirepoints for fouling rounds, because they are much cheaper. If I forgot my ammunition at home, and only had the fouling hand load rounds on hand I would definitely not hesitate to shoot them out to 300 yards.

Best of luck this year!
 
For me they were spent on woodchucks and showed their weaknesses in accuracy. Or maybe their limits to shoot at range. I was lucky to load a 170 grain round nose partition in my .30-30 and just flat out killed stuff. Yes, they always ran and trailing was a standard thing but I knew they weren't far.

Then, I keep my ears and mind open. Older friend always used corelocks and went on moose hunts so forth. He always had a story about hearing the bullet smack a moose at 400 yards near dark they just couldn't locate. He still won't accept he is the weak link in choices he makes. He would never spend $4 on a premium shell when he still has three boxes of mushrooms the gun loves. Even though these hunts cost thousands!! Ugh my lord!!

And finally, I love setting the odds so highly in my favor I can't "lose". Missing, wounding or wasting half an animal because I made an inferior tool choice just isn't an option.

Cor-Loks were good enough for minute of deer to 2-300 in most rifles, scopes (not dial up optics) and capability of shooters. Though a box of 20 seemed to last 10 years. One shot at 50 to verify 😱 and one to kill sumpthin and put rifle away. Maybe run an aluminum cleaning rod with piece of T shirt and 3 in 1 oil down bore from muzzle. I think I knew a bunch who did this.

I understand it was illegal to shoot anything but 170gr Cok-Loks out of Mod94's? Especially in Adirondacks. No ammo at hunting camp? No prob, 1/2 doz guys all had same stuff.
 
I will admit that I bailed on the old soft pointed bullets at some point for boutique style tipped/hollow point bullets with shiny nickel brass and fancy names. I just can't recall why. Last 5 deer in shot dropped in their tracks with a well placed shot with minimal damage. Distances were from 70ish yards up to 300yds. Bullets usually had a small entry and the exit if there was one was about the size of your thumb. I know these style bullets will not work for the majority of this forum strictly because they have the BC of an ACME brick.

I just went thru some of my ammo crates after the bullet construction thread. My comments made me pause and seriously recall why I quit using the pointed soft point ammo. I stopped looking when my back started hurting from moving them out of the closet to the center of the bedroom.


223/5.56 ammo crate was filled with several thousand rounds of various brands of FMJ/Tipped/BTHP/Fusion soft points. Some are specific purpose ammo, Fusions were great for around the house and chicken coop, even killed some big pigs with them up close, 50ish yards.

243 ironically was filled with nothing but pointed soft point 100gr stuff.

6.5 Grendel was Nosler Ballistic Tips cause they flat kill and there's no tracking, but they are not meat friendly.

6.5 Creedmoor was a mishmash of almost 3000rds of stuff usually purchased from members of various forums. Accubonds, Partions, Berger Hybrid Hunters, Elite Hunters, Terminal Ascent, BTHP, FMJ, LRX, and 1000rds of 131gr S&B Pointed soft points.

6.5 PRC is new to me so I only have 200rds each of Nosler Accubonds and Berger 156gr EOL ammo.

280 Ackley was Accubonds, Partions and handloaded Berger VLD-Hs.

The bullets I have used of these newer style concepts have all killed deer effectively and efficiently. I am a meat hunter, so I don't like wasting/losing meat to excessive damage. I was raised by my grandparents so everything we ate came from the woods or we raised it in the garden or pigs, chickens and cows.

We get 5 tags here in Texas and other than the occasional cull, I try to shoot does, more of them and they don't get the pressure bucks do. I am also not above taking a headshot in the perfect scenario, but that takes an alignment of the stars. The caveat is, a big doe is 120lbs hanging dressed out, they are rare on our lease, most are 95ish - 105ish pounds. We hunt over corn feeders, there is usually a kiddo tagging along or doing the shooting.

I rambled thru that to ponder the question, when did our parents and grandparents bullets quit being effective?

I am going to shoot the first doe of the season with the S&B 131gr pointed soft point, then possibly all 5 of them. They are consistent velocity wise and they are plenty accurate enough, plus they are super cheap, less than a $1 a pop. The box stated 2740fps from a weird 21 1/2" barrel IIRC, but I routinely saw 2830 to 2855, the 20shot velocity average was 2837fps out of a 24" Proof Sendero Light. Their stated G1 is .389 and the G7 was .195. The longest shot to one of the feeders is a hair over 300yds, so I think with the smaller stature of our deer, these will be a great choice. I am curious about the wound cavity. I shot a couple of biggish sows at the farm in the 180-200lb range, but didn't cut them open, one took a couple of steps and never twitched, the other fell in her tracks and did the curly shuffle and I stuck another one under the chin to shorten any suffering.

Thoughts, recommendations, any potential issues I am not seeing? If not, then a range trip to get more data with the Labradar, verify the data at the 200yd station and then verify at the farm at 300yds and 400yds. If I did my math right, 400yds is on the edge of the 1800fps minimum threshold for expansion, although I have not found a recommendation for minimum expansion velocity for these bullets. At the lease, 250yds will be the maximum yardage I attempt a shot and it will be the high CNS shot.

I am not in the same situation as most here, 400yds is a long poke. Most of my deer are shot off of feeders at 160yds, 220yds and 250yds but I have shot Antelope and deer in excess of 700yds, with a 240 Weatherby and a 257 Weatherby, my only bull elk was about 160yds with a 300 Weatherby. The cows I shot were anywhere from 60yds to 250ish. Lots of pigs out to 450yds, a few at close to 500yds and coyotes up to 700ish yds when I did nuisance control for the county.

***Edit***
My math was wrong, two different ballistic calculators put the 1800fps between 450 and 475, but that will be well beyond my goals.
😉👍 Like the old .30-30: Great deer rifle for decades but it's no longer good enough.

I still have the majority of a 1000 round box of Hornady 270 grain SP's, that are awesome bullets when kept within their best "operating range" 🙂…..but, not so great on close range shots when pushed @ AI velocities! 😉

They're great in my retired H&H, and if "push comes to shove" ……I'll feed them to the AI again! 😁 memtb

When I was 18 I bought a hornady starter single stage kit which I still use and the promo that year was "get loaded". Bought the kit, they sent ya 500 "free" bullets. I opted for the 130 grain .277" interlocks. Not every interlock behaves the same as the others in the line: that one is amazing honestly. I really don't know what a premium would do that they don't when used as a deer bullet which is what it is. No problem penetrating big Saskatchewan whitetail shoulders even inside of 100 yards impacting at probably north of 2900 fps still. Massive broad wounding. Usually exited, huge blood trails. The 140 btsp interlock in that caliber is a decidedly slower killer, also good penetration but no better and not as violent while doing the penetrating it seemed.

Yep, I'm pretty confident that the Interlocks were/are good bullets!

We also have a 1000 round box of the 130 Interlocks……bought as "blems" at the same time we bought the .375's. Both purchases have proven to be a good decision! memtb
 
The real answer, about 25 years ago when better bullets came along. I've been shooting ballistic tips and accubond for the last 20 years. Polymer tipped bullets simply have higher BC, more accurate, and provide much better expansion. Simply put, the newer technology just kills much better. Even short range on hogs, the 120-123 grain SST in a 300 blkout or 7.62 x 39 if far more effective than a softpoint. Can you still kill something with the old technology? Sure, you can use a shotgun with a slug if you want. I think the question is, why are you still using them? (I still have boxes of them sitting on the shelf, I don't hunt with them if I can avoid it) My guess is you're using more modern powders, more modern primers, and potentially a more modern barrel even if you are shooting an older cartridge like a 308 or 30-06. ( the 308 is still my favorite caliber, it's great with the new technology) Look at what technology has done just in the last ten years on rifle barrels. We have MOA guarantee on $300 to 400 rilfes from Ruger, Thompson, etc. etc. That didn't exist just 10 years ago. When I was a kid you'd spend a fortune on a gun that would shoot MOA and folks were in awe of a Remington 700 that would shoot MOA. Technology is moving so fast, I can't keep up. Look at what folks are doing with the 6.5's etc. I bet you have a cell phone and not a CB in your truck. You can still reminisce about the old stuff but better is still better and newer is better when it comes to bullets.
