I am wondering if and what types of loads people have been useing with the 160 GR Hornady Interlock RN bullets.
I have 600 of them and want to use them in my new Cooper that is on the way in 260 REM with a 26" barrle but it has a 1-9" twist, but I was wondering if the 26" barrle would help out for the slower twist ?????????

IMHO unless your rifle(.260) has an adequate throat depth and a long enough magazine length the 160gr. bullets are not the best to use even with an appropriate twist.

A 6.5 X55 would serve you much better with the long heavy bullets. roger

I agree with Roger however you can shoot the 160's in the .260 Rem

A 1-8" twist would be better but as long as you have the bullets just try them.....I'm guessing it'll all work out fine.

You can get 2,600'/sec out of the 160s in the .260 and that's quite a whack! I wouldn't hesitate to use it for some fairly large game such as elk or wild bore.

It is a Cooper 22 "Phoenix" it is a single shot Bolt, and well they are desigend to handle the 142gr Sierra Mach Kings wich are longer then the 160gr Round Nose bullets, so I thought they might work out.....

I am not trying to make them go fast get them to be accurate thats all if I can get them to go 2200-2300fps I would be VERY happy...

Just went on Hodgdon web sight and yes you can push them good it looks like 2500 is about avg for the 260 rem...

I loaded some 220gr round nose Hornadys in my custom 7.62X54R with a 19" barrle and alot of people told me it wouldent work in the old WWII gun that the .310 bore was not going to wotk with .308 bullets and that the twist rate was not suted for it.
well for a gun that is under 2100fps it shoots them very well keeps them in a 1.125 group at 75 yards with a 2x20 Scope

the 160gr 6.5MM bullets are 1.238" and the 220gr 7.62 bullet is 1.254", i am willing to bet the 160gr would work in 260rem even with a 1-9" twist, if they are going the right speed

I loaded and shot some 155gr Lapua Megas in a 260 Rem. Mt. rifle a few years ago and they worked just fine in fact it seemed to prefer them over a few of the lighter weights.

I have several brands of 155 through 160 gr 6.5 bullets that I am planning on working up loads for one of these days.

Will post results then.

Well with your clarification there, then you are adding a lot of realistic expectation to the equation...

I shoot them usually in the same MV range...

My favorite load is 30 grains of RL 7 behind a Hornady RN... I've only got a few Sierra 160s left and I used them in the Mauser I have...

Both of the 4198s can be substituted for RL 7 with 25 to 30 grain charges... accuracy has always been perfect in my 260s ( got 3 of them)..just pick what MV and accuracy, your rifle or you like best...

SR 4759 with charges of 22 to 25 grains also should give fine accuracy and at 25 grains should be in the ball park of the MV you are looking for...

only downside to the 160s in a 260 Rem is that folks want to redline velocity potential...

If you want to see how much penetration those 160s will give you at 2200 fps MV, launch a couple into a tree in the woods, or take some milk jugs full of water out and line them up..
but If you do the milk jug test and want to recover your bullet, you'd better line up more than half a dozen milk jugs... at 100 yds, each time I have done so, 6 wasn't enough to recover the bullet...

the 160s in a 260 for 100 to 200 yds, will easily compete with the 06 and 220 grain RNs for penetration... I can attest to that.. and don't get me wrong here.. I love an 06 with a 220 grain RN as well!

just the 6.5 bore is much easier on the shoulder to shoot...

good luck with em there 500 Mag!

Duck soup ! If you can seat it out far enough so it doesn't infringe on the powder space the 2600 fps. that VD is mentioning should be easily attainable and then some. roger

I have shot the 160 Hornadys for thirty years and have found them to be almost as accurate as the spitzers in both my 264 Win Mag and 6.5 Swede. I don`t think you`ll have any problems with the throating and leade. I killed one BIG bear many years ago with the 160 and it worked just fine[ not recommended though] but that was the 264 and velocity was about 2950. I wonder about the opening with the much smaller 260 case though. It may just punch straight through.

I'd hope so.....the velocity number I used came directly from Hornady's reloading manual. That velocity was produced by
1. 44 grains of imr-4831
2. 46 grains Rl-19
3. 47 grains imr-7828
5. 48 grains WIN WMR

It's interesting to note that the length of the 160 RN is about the same length of the 140 spire point. The extra 20 grains comes from filling out the round nose.

Yes, it does require a bit more distance to the lands but the amount isn't as severe as one might think.

A slightly freebored .260 becomes a helluva penetrator in it's range. But at 2600'/sec it's going to cover the first 200 yards pretty darn quick!

When I got each of my Ruger 77s in 260, I took them over to a gunsmith, with a dummy round of the 160 Hornady seated to the cannelure and asked him to ream the throats to fit the dummy round....

I also gave him a dummy round with the 160 Sierra seated to the same length... for some reason its nose design was a little rounder at the end.. where the Hornady would first chamber the Sierra wouldn't.. so they were reamed out to fit the Sierras..

however, since Sierra dropped theirs, it shouldn't be an issue...

but if one wants to shoot the 160 Hornady, reaming the chamber wouldn't be a bad investment.. however one would have to make sure the one in 9 twist would stabilize it..
