Home Forums Hunting & Shooting Ask The Gunwriters Winchester Copper Impact Bullet

While BSA has brass coming (gratis) for my recently acquired 270 WSM I was browsing what factory ammunition was available and see the Winchester is offering ammunition loaded with the 130 gr Copper Impact (CI) bullet. Does anyone have any experience with the CI bullet?

When you first started this thread, I was hoping someone had some input on this ammo. Pros and cons. Does it copper foul like the older Barnes? Then on the other hand, I'm thinking if you can find any ammo for the 270 wsm, that is a plus. That cartridge is a dying/dead one. Much like my 300 RSAUM. Love that cartridge, but it's fine if you handload and can find brass. Good luck with that rifle ed. It should be a good shooter.

Lawrence,

That is exactly what I was wondering. I suspect not as a lot has been learned since the original Barnes. Franky, I was surprised see it in stock at places like Midway.

Have never been tempted to try the Winchester bullet, mostly because it has been generally demonstrated since the early Barnes Xs that pure copper without enough circumferential grooves to mitigate both pressure and fouling tend to have iffy accuracy, partly because of fouling.

Which is also why so many of today's monolithics aren't made of pure copper, but gilding metal, the copper/zinc alloy used for most centerfire jackets.

Two boxes incoming so we shall see.

Will be interested to hear the results....

Good luck. My only experience with the CI bullets is in shotgun sabots, where there's no copper fouling issue to be had.

And the 'fire brain trust takes another hit...

Wow! One shot from a 9mm bullet with an advertised muzzle velocity of 2325 fps on a whitetail doe at under 100 yards.

They just might foul the bore more in a .270 WSM starting 900 fps faster, which might affect accuracy at longer ranges. Or they might not. In my experience with pure copper bullets, especially those without several grooves, the results can vary....

About 3 years ago, 2 Ruger M77's, one a tanger the other a mk ii both 270 win. Two boxes of win CI all over the target. Shot em up for the brass and never looked back.

I bought 100 rounds of the 125 grain 6.5 CM Copper Extreme Point ammo and shot 60 rounds of it from 4 different rifles. For me, it was not as accurate as the 125 grain Deer Season XP, my preferred factory load for shooting deer with the 6.5 CM, and since I didn't shoot much of it, I didn't notice any particularly bad copper fouling.

The most accurate factory load that I've shot in my Remington 700 in 270 WSM has been the 130 grain Power Max Bonded, the same holds true in 270 WIN.

I have a Kimber in 270WSM and a bunch of the 130G W solid copper. Shot a box and a half, did not notice any copper fouling issue. Decent accuracy but not as good as some 130G RWS I picked up from NECG.

edit to add PS, I see they still have 3 boxes in stock apparently. Not cheap but shoots well in my gun.

Had some Barnes X for my 7mm rem mag. They shot about like buckshot.

Please don’t tell the 243 Win version this info

Having said that, it doesn’t do anything other ammo doesn’t do.

Can only guess what you're stating.

But before you answer, will also note that even the early X-Bullets would group well in SOME particular barrels, but not in others. The problem partly turned out to be not just the bullets themselves, but how well their diameter matched up with specific bores.

I bought it because it was fast and on the walmart shelf. Shot fine in my rifle but performed on pigs the same as anything else.

I won’t stay with it, I have always just settled on whatever walmart or academy has in stock most of the time which is usually Fed Blue box, Win PP, or Hornady fast stuff.

OK, thanks!

It is this stuff

I bought some 6.5 cm and 3006 at my local Academy they had on clearance for 19.99 a box. I bought it all, 6 boxes each I think.

After the win rebate they have going it is 16 bucks a box. Too cheap to pass.

I will run a group or two through some known accurate rifles next time I get to the range and report back in. The BC is kind of meh, we will see.

May be a bit as OSU Sig, Chopper and I are heading to my ND place in just over a week for some ducks and pheasants.
