I have a Marlin 1894 in .357mag that I've been using for CAS. I'm going to start hunting with it so I've made up a couple of loads for it. I'm shooting a 160gr RNFP WW boolit over 14gr of 2400. I'm not getting any pressure signs on the brass so I'm sure it's safe. My question comes to this. How fast is this going?
It's pretty accurate, I had 5 rounds in a clover leaf at about 50 yards. I don't have any excess leading or keyholed hits. And I'm getting insane penetration. I set a 5 gallon bucket full of dirt on its side and shot it end to end. My boolits exited leaving a massive hole in the rear. So that means that they went through over a foot of dirt and still had the energy to embed themselves into the back of the ditch. I recovered one out of the twenty I tried. It got me to thinking. In my manual it showed that this should be traveling at just under 1700 fps. I don't have access to a Cronograph or I'd use one. How fast do y'all think it's going?

I'm guesstimating 1600+ anyway...

The only real way to know is to put it over a chronograph...

Yeah I just don't have any access to a chronograph. Hoping there was a way to get close without one.

Using the Lyman 358429 (170grs) over 13.5/2400 I get 1650 fps out of a 20" Rossi .357. As a previous poster said 1600+ would be my guess also.

For hunting, you might want to go to a flat point. You didn't say what you were going to hunt. NOE makes some real nice .357 hollow point molds too.

It's a round nose flat point. I'll be hunting hog and some deer if I can get close enough.
What I figure is that my boolits average 162gr + or - .5 gr, sized to .358. I'm using Winchester brass and magnum primers. With 14gr of 2400. My Lyman manual doesn't have a 162gr RNFP but it has a 155 SWC. So, I'm thinking that I'm a little ways off from what the manual says. However, I am getting very accurate loads with great expansion from the few that I've recovered.

I think 1700 FPS is an accurate estimate. Given what you've written about the load's performance it sounds to me like you have a winner. I wouldn't hesitate to use it for deer or hogs.
I have the same gun and my load of choice is a 158 gr RNFP over 13.5 gr AA #9. This load has been clocked at around 1775 FPS, and has taken two hogs, 85 and 120 lbs.
Good luck with you're hunting.
