CVA Kodiak 45 problems....

[USMC-Mustang]

2 years ago I purchased a CVA Kodiak magnum 45 cal topped with a Leupold VX-II 2-7x33. (1:28 twist)
The two types of bullets I've used are PowerBelt and Shockwave (several different bullet weights) with 100 grains worth of powder pellets. The best accuracy at 50 yards has been 4 inch groups.....very discouraging. Should I try 150 grains (it is a magnum rated at 150 grains) and different bullets? Should I use 209 primers vice the reduced flash muzzleloading primers? I've been thoroughly cleaning it after each shot so I know that isn't the issue. Anyone else have a Kodiak 45 cal that can group?

CVA's service manager advised to not use 150 grains for best accuracy even in the larger .50 caliber Kodiak, and to use the Winchester 777 primers and to pre-lube the barrel.

"I would suggest that you use the 2 of the 50 grain Pyrodex pellets or Triple 7 pellets, also use the Winchester Triple 7 primers , pre lube your barrel, put a little all natural lube on a cleaning patch and run it down the barrel follow this with 2 dry clean patches one at a time fire a primer then load the gun, I would use a 295 grain PowerBelt bullet. After you fire then run one damp, just from the moisture in your mouth, patch down the barrel and reload and shoot, do this between each shot. Repeat the lubed patch and 2 dry patches after 4 shots."

You probably need to try another bullet & sabot combination.

You don't mention which powder or bullet weight you're using, but loose powder might allow you to customize the powder charge better by going up or down in 5-10 grain increments. You could always try another brand of powder too.

Therein lies the problem with pelleted powder, aside from price. It doesn't allow you to fine tune the load for maximum accuracy. Personally, I'd suggest buying loose powder and using a powder measure to find your best load. It's almost always under the rated max.

different powders

I have several muzzelloading rifles,you have to spend a little money and time on different loads to see what your gun likes.I do know that 777 powder has a slower ignition compared to pyrodex.This could let you pull off a little bit.I have used loose powder 10 or30 grainsin front of the pellets to finetune a load without any problems.If you use all powder another varible inters the picture,if you don't pack it the same every time shot placement will change.You can use up to 30 grains infront of 2 pellets and not worry about the packing problem.I hunt with a Thomsan Center Hawkins with a Green Mountain Barrel that has a 1-28 twist.I load 20 grains of loose pyrodex powder first then 2 .50 grain pellets with a 295 grain powder belt.I can't shoot the pellets in the side hammer without the 20 grains of loose powder in front, they won't ignite,but the combination works perfect.I can out shoot the inlines I have.By useing the pellets the packing the same everytime goes away.I guess the point is don't change everything at once. Try one thing at a time and see if it helps. Gool Luck, have fun.
