What's up with no lead conicals over 400 CVA Accura
I just got a new CVA Accura 50 cal, 27" nitride bsrrel. Was planning on using 450 gr conicals that I cast. In reading the manual I read no lead conicals over 400 grains. This is supposed to be a magnum rifle that can handle 150 grains. I don't shoot but around 80 by volume of 209. They show a 444 gr copper clad in their powerbelt pamplet. I've already shot about 20 450s and getting a good group at 100. The rifle seemed fine to me. Anyone know what this is all sbout?

I still find this amusing and that they still include the warning in the most recent manual.
CVA's load data in the manual is barely even generic. They make no distinction between the most common loose subs and BH209. So when you claim its totally safe to use 150gr of loose powder by volume, people get the idea its safe with no matter what bullet you want to shoot. They still flaunt the "Magnum Muzzleloader" advertising like so many others. Well its pretty obvious that a 150gr load with some bullets might just get you into some VERY high pressures.
Use 150gr by volume of BH209 and a really heavy bullet will easily get you into dangerous territory. Even with a 300gr bullet that load is well into the 30kpsi range. Westerns own load data stops at around a 444gr and 100gr by volume.
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.

I'll repost my answer from CVA

This is right out of the manual they have listed online for an Accura. It even has a pic of a nitride and mentions the nitride finish so its rather current.
Now come on, even Traditions specifically states that BH209 max is 120gr by volume in the Strikefire manual. Some of their manuals even list loose T7 as 130gr max. They also have the decency to list load data for several powders....It aint that hard for the "just a better gun" company to list safer load data in the manuals.
CVA in-line gun designated as a “Magnum” is 150 grains by volume. This maximum load is generally known as the “magnum” load and is best suited for pelletized powder due to the more efficient burning characteristics of the powder pellets. Magnum loads of loose powder may be shot but are not recommended because of their inefficient and incomplete burning of the powder.

Depending on who you get on the phone they'll tell you to ignore the manual or not. They don't need to know what you shoot unless you tell them.
I hunt the rifle seasons and don't have to deal with the muzzleloader laws in Colorado. Easier to get tags too.
btw...a .54 PRB always worked for me for elk when I did hunt the muzzy season. Elk aren't so tough to need a conical over 400gr. I use a 250gr Barnes now. A Thor that size would be fine if you hunt the muzzy season.

LongBow call Western powders too. Im certain 80gr of BH209 by volume is safe with a 465gr in a 50cal. Assuming its used in a modern inline of good quality. I shoot upto 80gr by volume in a Knight 45cal with a 460gr conical. Its fine and a 45cal makes higher peak pressure with the same load and bullet weight. Western approves of upto 100gr by volume and a 444gr PowerBelt which is nothing more than a copper plated conical wearing a skirt.
