hey i can get ahold of 7mm interlocks fairly easily, eldx not so much right now but i nabbed 200X , an im out of SST, im thinkin goin to interlock in general wont be any decrease across the board for 0 to 500m huntng?

with the rem mag , what yas rekon, realistically.... should be better than a SST up close? and not quite as 'flat' as the eldx at 500m... but not much different to the SST looking at the shape?

thanks
 
What weight?
For 162's, STT Superformance and Eldx its only 2" drop difference at 500 yards, drift is only 1 inch ish. My experience with STT's in 270, I that up close at over 3000fps, its iffy.

There is a feller in NZ I believe running a site called Terminal Ballistics Research - he recommends candle annealing the SST in 7mm to increase its performance beyond what an SST should accomplish. If you're not familiar, just google Terminal Ballistics Reasearch 7mm Rem Mag and scroll down to the handloading section on hornady bullets. I have NOT tested this or tried it, but what he says DOES make sense (to me at least).

yeh not enough to worry my hunting, neither would the shape of the 160 ppsn .. i have plenty eldx to start! but will punch paper with the interlock in futurw!
 
In 257 the sst is more violent then the interlock but when shot into deer the sst actually holds together better meaning itll hold its jacket almost always. The interlock may slip the jacket. Both are very good bullets for lung shots. The sst seems to penetrate further before very rapid violent expansion whereas the interlock seems to expand immediately on contact

My experience, the SST pretty much explodes on impact. The interlock does not. Both separate more often than not out of my 7mm, but the interlock penetrates further.

yeah this is what ive found too, even testing into medium an having the camera zoomed up.... other projies bury into the dirt, these SST just hit the surface an explode. finding shrapnel in the dirt bank... where as the others, im finding projectiles lol.

ive made up my mind here- thanks for the tips.

interlock for shootin often, down here $60 per 100... eldx $88 / 100
 
In my wet newspaper test, the Interlock and the SST behaved pretty much the same.

In my 270, the STT shoots great.
I have shot a coyote at 200 yards with that load, It did not exit. Just saying. I still have boxes of bullets to load, but will only use them for target and coyotes. The last mule deer I shot with that load was a kill, it only went 15 yards, but even though I shot behind the shoulder, that shoulder was toast, the bullet blew up and did like a 90 turn. It was kind of expected as it was a 75 yard shot.

bcsteve, I'm willing to bet your Hornady bullet box says your SSTs are indeed interlocks.

The sst bullets have come a long way from what they once were. I like them and load the 140grn in my 6.5x55 tio slightly over 2800 fps and 140 grn bullets in my 7x57 appx the same velocity.

Both do the job very well on game.
 
typically the flat base is a better hunter than a btsp, ive got a few spider web lookin jackets from the sst, sharp an nasty, i can see how they get it done without needing blood trails..
just too in between for me i think.

even the eldx is fairly violent but its much more publisiced, or marketted that they hold together better close etc. so thats all good.

great photos BC steve!

i rekon the shape is very interlock BTSP shape aswell as above mentions, hence why i thought they will do whats needed fine.
 
Almost any bullet will kill a deer, since they are pretty fragile in structure.

But when hunting bigger, tougher game, those thin jacketed bullets are not
the best choice. Opt for a known good bonded bullet, or a partition. Then
you do not have to be so picky when you are presented with a quartering
shot, or where you may encounter substantial bone. Dave.
 
I prefer the older interlock, solid base bullets to the SST. The 6.5 129 grain interlocks in particular have been stellar for me at moderate velocities of 2800 fps. The same SST bullet at the same velocity killed and shot well however was less likely to exit and created significantly more meat damage. Another great thing about the older interlocks is they shoot so similar to a Nosler partition with the same load and rifle that they can be used for practice and preliminary load work up. Perhaps they have changed in the past few years as many of my boxes are likely 20 years old, or more! The next component bullet I want to try is the federal fusion bullet. I believe it is a bonded core and it is absolutely amazing what it will do in the little 7.62x39. There are so many great choices but stock up when you find something you like because supply is always an issue, and always has been.
