Home Forums Hunting & Shooting Deer Hunting 270 wsm Copper impact. What to expect?

Greetings All,

Based out of supply and demand I have purchased five boxes of Winchester deer season copper impact 270 WSM 130 grn with an advertised muzzle velocity of 3215 ft./s. I have never shot an all copper bullet before.

I will mainly be deer hunting with these in eastern North Carolina where our deer are small. Wondering what to expect out of this load? Is this something that will open reliably on a 80 pound doe at 75 yards broadside or is this a bullet I want to stick to shoulder shots with?

Also we do have some pretty large black bears in the area. Is this something that will penetrate well on something this size? Thanks all for your help in advance

Having no experience w/ that particular bullet, but .270 Win. mono-copper in that weight...

Out of a WSM?

Would expect no problem at all inside 400 yards.


But you get what you get, which is generally a lot of penetration w/ moderate expansion.

For those bullets, like to either drive them through, or into, bone.

Off-shoulder is preferable, as there will be less destruction when it gets there.

High, through both sholderblades on a broadside, also works.

I use them, shoulder shoot, DRT

thanks for the advice so far all

I would expect real dead deer real fast with shot placement in the vitals!

I've used Barnes TTSX coppers from a 308 on deer for years. They open quickly and the peeled pedals are like razors. They penetrate beyond anything conventional. I would expect similar performance from the winchester coppers

Thanks all for the replies.

For monos, I like to shoot for the shoulder. I have no reason to shoot those, much, and just stay with lead bonded or standard cup-and-core. "pocket" shots for them and save some meat.

Hopefully it works better then regular Deer Season ammo .

Guessing you had issues with it? Performance on game? Accuracy?

Yea they are excessively destructive on game and you can throw accuracy out the window. On a good day 2 " out of my Tikka T3x which is SUBMOA with Federal Blue Box. I have 2 boxes of 06 in the house which are for sight in only.

Good to know oldelk thanks for the reply. Being solid copper hopefully these will hold together better.

Scott,

The ones I own are solid copper and they have terrible accuracy. The lead core Deer Seasons were better in the accuracy department.
