new cva
#42
I just bought a 45-70 CVA scout to convert
I wish you had some big ole conicals to try in it. I bet it would be a hoot with a 465gr and about 75gr of powder. That would be a killer "brush gun" load.

So there.

I shot NoExcuses 460gr all the time. Before doing it I called and asked CVA and asked what was up with that when they sell 444gr Powerbelts. He told me to ignore the warning. They know it was a mistake, but the manuals are printed out and they're aren't changing it.
So there.

Hell if Knight can put out new info for BH209 limits then it must be pretty simple considering how few people they have. Print shops have those files in house usually. It would take a typesetter a couple minutes to make the change for the printers.
But to further my point. CVA strictly forbids using 3FG of any kind (verified by their tech) and bullets over 300grs in sabots too. Tell them you used either and they can void your warranty. A tech told me this more than once.
Its also about time they changed the 150gr max for BH209. They mention it in the manual but don't state the 120gr max by Western. If they can update a manual include BH209 plug info they can sure clearly state it has a different max powder rating too.
BTW i LOVE this tidbit. I never knew you needed to clean between EVERY sabot load to prevent them from getting hard to load....This is a riot.
However, most sabots leave a heavy plastic residue in the bore requiring cleaning of the bore after every shot. This plastic residue along with the extremely tight fit of most sabots makes loading for quick follow-up shots very difficult.

Hopefully with all the new folks they've brought it, they'll update their manuals to real day load info. Even Traditions allows 3f in their rifles while cva says its for .45cal and below. Its just outdated info from the 60s-70s.

Years ago, i made shims to reduce head space of the old model Accura, and later used them in the new model Accura too.
Ironically, this excess head space is helpful if one wishes to use the metric o-ring to reduce blow by. One can take almost any CVA rifle, stuff the o-ring into the primer socket, and shoot it. Far and away the easiest way to solve blow by, of any rifle. Western Powders even includes some o-ring with their breech plug. One cannot do this in TC rifles; head space is consistently near perfect.
Another thing done years ago, was to make breech plugs that would reliably ignite Blackhorn in CVA rifles. These plugs were intentionally made several thousandths longer than factory plugs, because the rifles had excess head space.

Ron........With 209 primers being all different lengths. How can CVA accurately set the head space? All they can do is be on the safe side of the longest primer. The idea of crushing the primer to remove blowback is not something a factory will do.
So, all a CVA can do is pick one primer to use all the time and shim the headspace to that primer. They can also take the easy way and use an o-ring. I personally, don't like using the o-rings. They shim out the primer too much and the primer falls out too easy. Installing the shims is easy enough.
