6mm /.243 hunting success on Big Game

[omicron1792]

It’s violently effective. I don’t really have experience yet though, besides for two deer yesterday. Mine at 414 with the full pass though and football size exit and a 90 yard shot by my buddy. He hit high shoulder, through the upper scapula, spinous process and caught in offside hide. Softball sized wound cavity there as well.

Looks like yall are having a little too much “fun”….

@Formidilosus or anyone have any experience with the 6mm 95 HPBT matching on game. Just found a promising load in 6 arc. Calling them hollow point is even a bit of a stretch as the meplat pretty much comes to a point. Have to file flat before a guy can even open them up. There is a pretty large cavity under the point but not sure if it will fragment like I would like. Wish I could find the tmk but no luck. Anyone shot a critter?

Man I bet that buck was a stunner when he had both antlers! Looks like he had a bit of a tumble.

Just hidden. He did tumble quite a ways but no damage occurred. But check out those growths on the velvet.

If you mean the Sierra Matchking HPBT, I would not suggest that bullet for hunting. It is a “closed nose” design and is sometimes extremely variable in how it performs in tissue. The 95gr Berger VLD and Hybrud Hunter, 105gr and 112gr Barnes MatchBurner, ELD-M and X’s, etc are all much better/more consistent in tissue

Yep that’s the one. Thank you. What I needed to know

Bottle fed squirrel = marten food

Possibly, but we gave him a chance in any case, when he would have starved. Nature will take its course in one way or another, but for now he loves life and to play.

Indeed that is all you can do

Grabbed a couple of boxes of 95 NBTs. Still need to find LRPs though.

So I picked up a compact 243 new for a steal. Such a steal my wife also picked up the last one. What’s everyone’s thoughts on 80ish weight coppers? 1:10s I think.

I think the general consensus is don't shoot copper unless you have to.

 

[Ringbill27]

6mm or everything? Cuz I’m using copper for all things these days. Don’t have to just do.

I have had better luck with the terminal performance of traditiona lead bullets. If you want a not-so-brief synopsis, the 223 thread is a good place to start

Did you put them in a stabilization calculator? It sounds like it could be borderline.

I ran some fake numbers through a couple calculators. At about 200ft elevation and 32F, a 20" barrel with Hornady factory 80gr cx (assume 3000fps) would be marginal stability or not stable, I think. It's weird they don't give a min twist for either of their copper 243 bullets or for their loaded factory ammo for those two bullets in 243 win.

calculators I’ve tried using ask for the bullet length and most manufacturers don’t list that in the specs. So without the bullet in hand how do you use the calculator accurately. Edit: more list lengths then I thought.

Barnes’s 80gr 243win load is rated to 1:10 and faster. They seem to be the only manufacturer that does or at l at I’ve found so far.

This has most of the bullet lengths.

Interesting didn’t know this existed. So if a bullet were marginally stable what would I expect to see? Keyholing at 25yds or weird things are longer ranges?

My experience with marginal stability has shown up by 100 yards when supersonic and by 50 yards when subsonic.

Ive shot 80 grain barnes out of a 1:10, they shot fine. Killed three deer with that load and was underwhelmed with the performance. All three died, but traveled around 100 to 125 yards. The wound channel reminded of the damage you would expect from a broadhead. Very minimal meat loss though, and I was killing does in crop fields with depredation permits so long blood trails weren’t a problem, just shoot and watch em run till they tipped over.
