Recovered 143g Hammer Hunter from 868y cow

What powder? N570 with that speed?

You couldnt get nearly enough N570 in the case to pressure up a 145.

I believe he is running Retumbo. I think he has a fast rifle. We have never been able to duplicate it.

We have been running N570 with the 143g HH and get to pressure. Give or take 3600 fps depending on the rifle. N570 compresses nicely along with a 6" drop tube.

You did get enough in
I guess I stand corrected

Killed over a dozen deer with Hammers this year in three different calibers. Haven't retrieved a single bullet. They don't stop on/in our small deer

I just got this pic sent to me this morning from our Customer Terry with this note.

This is a 7mm 143gr Hammer Hunter removed from a cow elk. She was shot at 868 yds from a 28 Nosler running at 3650fps. It was a hard quartering shot that broke the front shoulder and the off side hip. It was recovered between the meat and hide in the off side hindquarter. Recovered weight is 102g. Cow never took another step. Conditions were at 8200' elev and 20*. Puts the impact vel at roughly 2230 fps.

This is exactly the performance we are after. 70% weight retention with a nice square flat frontal area on the retained shank. Looks identical to bullets fired into test media. This bullet still looks the same even though it encountered two heavy bone impacts with perfect straight line penetration. Fantastic! Thanks for the pic Terry!

Terry, that owns that rifle, is running Retumbo I believe. We have not been able to get the kind of vel that he is getting with Retumbo. We have gotten 3500 fps or so. With N570 we get about 3600 fps or so. I think Terry has one of those fast rifles!
