45-70 250 Gr. Shock Hammer

[01foreman400]

I finally got around to doing some load development for my CVA Scout 45-70 Suppressed. I was shooting the 250 Gr. Shock Hammers. Using AA1680 I was able to a chive a 3 shot group of .935”. Velocity average was 2,964 fps. Unfortunately I forgot to take a picture of the group as I was shooting multiple guns that day. I did however take a picture of a pine tree I shot with this gun and my 7mm-08 118 gr. HHT’s and 6.5 CM 125 gr. HHT. This was the result.

The 6.5 and 7mm-08



No exit for either.

That is what I call a wound channel that any beaver would love!

That's some impressive speed for the 250 SH.
My 2604 fps was the fastest I'd known of from a 45-70 with that bullet. You just walked right past that. That AA1680 powder can really push that bullet. It's what I run also.
I'd love to see what that can do on a critter.
How's that brass life?

I saw no signs of pressure but maxed out of case capacity.

I was able to cheat my OAL out just a little and still get the loaded round to eject from my lever action. It gave me more powder capacity. Would you have room to be able to do that? Maybe hit that 3k fps range.

I’m a touch above factory OAL and as long as I can go. How much is too much powder? It’s not like it’s at the top.

To much is when it says uncle. Or your shoulder does.

Y’all are a bad influence. The load that got 2,964 was 63 gr. I loaded up some 63.2 gr, 63.5 gr and 63.8 gr. I’ll keep y’all posted.

You got me looking for a good single shot 45-70.

I’ve got 4 Scouts and they are great rifles. Excellent triggers.

I only have the 45 70, which is now a 45 90. Yes, they have nice triggers. Had to epoxy scope rail

The stock rail? I use DNZ mounts on mine.

 

[joe16]

Never tried those.

First thing I did on my CVA pistols was take off the rail, clean all of it and locktite it back on.

Ruger #1

Hard to find especially in stainless but that would be my first choice.
It looks like the CVA would be a good poor man's hotrod.

If I had to put money on it, I bet that cheap CVA will out shoot and have a better trigger than that high dollar Ruger #1.

Looks like I can get one in stainless for $400 plus shipping.
I showed it to my daughter and told her to get it for Father's day
