Hornady Interlock flat base bullets...Outstanding results

[whatnickname]

With the critical shortage of components, I’ve been trying some of the old style cup and core bullets, as my desired premium bullets just can’t be found. Midway had some Hornady Interlock bullets available in 270 (130 grain) and 30 caliber (150 grain). They’ve been around quite a while but are still reasonably priced....31 cents per round. Bought a few boxes of each caliber. I’ve never seen a bullet that was any less sensitive to powder or caliber. I’ve loaded these bullets in four different rifles using three different powders (IMR 4350, IMR4064 and Varget). My rifles are as follows: Winchester Model 70 stainless in 270, Sako Model 75 stainless in 270, Sako Model 75 Stainless in 308 and a Ruger M77 MKII in 30-06. These rifles are nothing special but all are accurate.

I’ve used Federal 210 primers and powder charges that I know to be accurate with those weight bullets. All these rifles shot sub MOA groups and three of the four shot one hole groups. All seem to shoot best with the bullets seated .055” off the lands. All in all very impressive with a bullet that I’ve concluded is inherently accurate. Who knew?

I like the Hornady flat-base bullets... as you mention, they are excellent bullets if BC isn't critical.

150 SP Interlocks over a load of IMR 3031 is my go to deer load in my 303 Brit. Accurate and very effective on Whitetails.

All the old timers knew flat based bullets were more accurate up close.
My dad used to joke that boat tails are for easier bullet seating. He shot inside 300 yards though.

Given the choice I'd prefer more modern bullets. But I've killed enough game with those to know they work. I have a bunch of old school 165 gr Hornady's loaded up for my 308. They are plenty accurate and would do what I need to do 99% of the time

I agree most of the time.
I do run flat based bullets in my iron sighted rifles. They shoot relatively slow and don't need help inside my comfort zone.

At least 99% of my shots on deer in Oklahoma are under 300 yards and a good number of them have been between 100 and 200 yards. Once in a great while I will shoot at distances over 300 yards. Took a doe at 457 yards one afternoon with a 115 grain Nosler Ballistic Tip that left the muzzle of my 25-06 at 3100 FPS. That’s the exception. At the distances I normally kill deer I’m thinking those flat base bullets will work just fine.

Well the cup and core bullet is a simple design that is over 100 years old. For the price point they are great performers in the 100-200 YD range. I generally liked CorLokt and the Seirra Grand Slam bullets. Hope that RP offers the CL as components again.

The Hornady 270 grain SP flat base was my bullet of choice prior to the advent of the Barnes Mono bullets! I had excellent results until I pushed them beyond 2900 fps and used them on a close range shot! They still stayed together and gave a beautiful mushroom, but with the large frontal area and approximately 35% weight loss, penetration was found to be lacking! memtb

Good to know. I have a box of the 150 grain .30 caliber Interlocks I'm waiting to load up for a friend who can't find his favorite Core-lokts anymore. (I believe I read that Remington discontinued them.) Pretty much all of his shots will be under 150 yards, so it sounds like the Interlocks will fit the bill quite nicely if we get results similar to yours. I was going to try either H4895 or Varget because those are the powders I have the most of right now.
