How’s pelt damage been with the 88s for you?

I’ve killed dozens and dozens with 88 ELDM and 80 ELDX with VERY mixed results.

Some pelts are unusable. Some are fine.

What would be your choice to maximize internal damage and minimize external damage? I'm thinking about wolves from 300-700 yards.

55 VMAX staying off impact side bone but not for yardages that far. I’d probably go 80 or 88 ELDM over the 80 ELDX and 77 TMK.

My father in law and I will be experimenting with some of the heavy for caliber Berger bullets this spring and summer with 22 Creeds.

If I’m being perfectly honest, and I’m trying to collect pelts to salvage and sell, I’m shooting them at maximum 300 yards and 100% head shots with a 17WSM.

I shot the Berger 80.5 this winter. They were going 3350. They did surprisingly well on fur. Most normal shots there was no exit.

If I wasn’t planning on using a can I would get at least 22inches of barrel

Why do you say that? Genuinely curious.

A lot less blast and noise will make it much more pleasant to use and give you at least 150 fps more velocity

Likely has to do with a 20 shot string.

Rpm and heat are what seem to make bullets pop.

Sorry, im just a retard. Never knew this could be a thing. Can anyone explain why it happens? My retarded mind can't understand. Thanks!

Somewhat common with fast 22 cal. Spinning the bullet too fast can make it explode mid flight. That’s the reason why there is so much barrel twist talk in the 22 creed thread.

The actual science on it, I don’t know. Hornady talked about it in a podcast.

Gotcha, ill have to go look up that podcast! Thanks for the info.

It's the centrifical force from spinning put on the bullet. This is a force away from the axis of rotation this can cause the bullet to explode if the force is greatee than what the jacket can withstand. This increases the faster the bullet spins which is determined by the twist rate and muzzle velocity. Ie 3000fps = 2,160,000inch per minute divide that by the twist gives the bullets rpm. Ie a 7 twist is 2,160,000/7 = 308,571rpm. Eld ms are known to start having issues around 300,000rpm.

Once in this danger zone lots of things matter from barrel condition, barrel heat, bullet construction, actual barrel bore ie .218 bores are worse that .219 bores as it damages the projectiles worst compromising the jackets ability to hold together.

Also the reason Berger many years ago went to a heavier jacket for their Target bullets and kept the lighter jackets for the then re-named Target's into the "new" Hunting bullets. Many Target bullets were blowing up during long strings of competitive fire so they made the change. Targets with the thinner jackets became the Hunting bullet and Targets got a heavier jacket. I think this also corresponded with the drift towards heavy for caliber bullets and the fast twists they required.

Both I'm willing to sacrifice for a shorter barrel that will live on a pack 99% of the time busting through the alders and willows. It's a barrel designed for a pretty specific purpose, killing goats and sheep in nasty country. I have other barrels and calibers for practice outside of hunting with longer barrel life and heavier profiles.

With an 88gr ELDM I'm still effective terminally out to 600yards, an 8" circle has a 96% hit rate

This is the AB Quantum app for an 8" circle, 10mph wind, 2900 FPS ... the biggest piece is calling wind as the confidence parameter says I can call it within 1mph. Something we keep working on but aren't great.

Feedback always appreciated.
