.243 105 BTHP minimum fps ?

[Joshuajosh]

Those that use these for a hunting bullet, what is the minimum effective fps for adequate expansion.

I want a minimum impact velocity of 2000 fps, but that's my minimum for basically every bullet I use.

Free bump for you because I’m curious as well. May be able to search the .243/6mm success thread with 105 as search word

There’s a little bit of info here.

Maybe to the contrary of some others here, but I saw some pretty wonky shit with those bullets. Most notably, an antelope doe that I shot at 400 yards with my 6 CM at right around 3k MV. Bullet hit the X right behind the shoulder and she flopped, but I didn’t see an exit. Upon skinning and quartering I found the bullet next to one of the tenderloins… so it made a quick 90* turn and stopped.

I killed several antelope does with it and all flopped for sure, but exits were sometimes dramatic. Also shot one bighorn ram at about 330, he died quickly (10seconds or so) but that bullet did not exit.


Anymore I’d choose the 108 or 109 very easily over the 105, unless you’re shooting a 1-9” and can’t get those to stabilize.

what makes you choose the 108 or 109 easily after having good success with the 105? Playing with WEZ calc, hit rates are identical to 108.

@Formidilosus in your experiences, does the 105 BTHP perform more like a DTAC with the yawing? If so, does that translate to the low impact velocity success?

Well, I wasn’t real pumped on the one bullet ending up in the tenderloin and didn’t really enjoy what a mess they were making in general. Antelope and deer and sheep are easy to kill and I didn’t figure I needed to keep hitting them with a hand grenade to anchor them.

That, and the increase in BC to the 109 was worth the extra cost.
