Home Forums Hunting & Shooting General Big Game Bullet Test - .277 150 Interlock

aheider,

The 150 Spire Point has long been one of my favorites in the .270. First stated using them in the mid-1970s, long before Hornady added the Interlock ring, partly because they were extremely accurate in my Remington 700 ADL. Using the original mil-surp H4831, muzzle velocity was around 2850--though I didn't know that until a few years later, after purchasing my first chronograph. That load would group 3 shots in an inch--at 300 yards.

A good example of the penetration was a big Montana mule deer buck, which weighed 232 pounds field-dressed AFTER a week of hanging. This was in the steep, thick timber country next to the Idaho Panhandle, and the buck was uphill at about 25 yards. At the shot it collapsed, because after entering the chest the bullet broke the spine at at the rear of the ribcage--and exited.

The Interlock version penetrates even better, as you have proven--which is why I always keep a sufficient supply on hand....

Just wondering, does anyone shoot the INTERBOND? Seems to me they would be even better than the interlock.

Good information, and good shooting! Just played musical scopes on my rifles, plus did some tweaking on my old lefty Ruger .270. I have a new stock, new scope, and a new box of the Hornady Interlock 140gr BTSP. Hopefully it shoots and performs similar to your setup!

Decided to do a little "in the field" bullet testing with the 150 Interlock out of my 270 win over the past 4 days. Handloads are a blistering 2800 fps out of my Tikka superlite . I was using a 3-10 SHV with the MOAR reticle.

First test: Cow elk at 250 yards. Slightly quartering away, hit her on the last rib angled forward. Caught the front of a very full paunch, liver, and lung. She ran about 50 yards, stood for a minute and fell over. Found the bullet in the rib cage against the offside still in the chest cavity. Bullet weighed 101.8 grains or 68% weight retention.







Second test was on a bedded buck at 238 yards. Broke both shoulders and found the bullet under the hide on the offside. The deer never got out of his bed. Bullet weighed 84.6 grains or 56% weight retention.









Over the past 25 years or so I have shot primarily accubonds and partitions for almost all my big game hunting. But with the current component shortage, Hornady seems to be the one manufacturer that is able to keep some bullets on the shelf. I would have no issue using the standard Interlock under 2900-3000 fps. I'm a fan.
