Here is the deal i got a cva optima in December. Just got it ready to shoot today. Set it up with 777 100 grain pellets with 250 grain hornady sst bullets with winchester 777 primer. The groups were not impressive at best 5-6 inch groups. Any advice to shrink the groups down? At a 100 yards it will group in a pie plate capable of killing a deer but not the acuracy i want. I was shooting off a lead sled

I quit using the pellets due to accuracy issues. Do you have any loose powder? If so, you might want to try some and see if your groupings tighten up.

You could go to 777 powder or Pyrodex and still use the breech plug and primers you have. Any chance someone close to you has grained powder you could try to see the difference?

One of the things granular powder gives you is the ability to experiment with different volumes (90; 100, 110, etc) to see which amount your gun shoots best. To just go with 100 grain pellets might be what is causing your accuracy issues.

I bought my Optima in January and went to the range for the first time 2 weeks ago. I got it sighted in at 50 and immediatelly shot a 1.5 inch 5-shot group at 100. I was shooting my old reliable combo of 90 grains of Pyrodex and 295 grain Powerbelts. I've killed dozens of deer with this combo out of an old CVA Firebolt. I was originally just going to shoot the rest of my Pyrodex and Powerbelts up, then experiment with other bullets and powder. But, why fix something that isn't broke. I think with a little range time, I can make this group smaller.

Some people hate Powerbelts, some people love them.

if that has the red low drag sabot, up the pellet load for a max load of 150gr pellets.

The sst/red low drag sabots load pretty smooth and easy, easy loading sabots in a cva bore need to be pushed hard with a healthy dose of powder.

Also, run a 3mm drill bit and with your fingers, spin it and cut the carbon out of the breech plug. Do this every 5 to 6 shots.

Also make sure you run a damp patch down the bore after each shot to remove the hard crud down towards the face of the breech plug.

Shoot some Barnes 290 or 300 gr blue tips.
Loose powder helps too.

leadsled isnt the problem, ive shot off a lead sled for years with excellent accuracy.

Your biggest issue right now is the sabots.

I looked through my videos and i used 2 T7 magnum pellets with the 250gr SST sabots. May give that a try along with the winchester w209 primers and swab between shots.

I had got an optima for my son to use last year. I shot 100gn blackthorn with 200 gn shockwaves. This shot close to moa all day long, and was shooting right at 1900fps. I did not get the blackthorn breech plug as it shot well. I only ran about 40 shots through it. I would ditch the pellets & go loose powder. Blackthorn was nice as it was much cleaner then the others. Hope you get it figured out as an optima is a fine ml.

nothing against optimas but ive never seen one group worth a crap. I know of atleast 6 people who cant get them to group. They've tried powder, pellets, powerbelts, hornady, shockwaves, etc and never can.

a lot of the times its not the gun but the shooter/lack of knowledge.

90gr blackhorn209, 300gr powerbelt aerolite @ 100 yards. Thats a 1" bulls eye by the way.


And topped off with a $30 barska huntmaster 3-9x40 scope.

Fullstream has got it right. Blackhorn 209 is as close as you'll ever get to a smokeless ML. Excellent velocity, accuracy, and also VERY clean burning. As for powerbelts, you may as well shoot a ball of lead. I did a cutaway of a 295gr HP Powerbelt after I had one explode on a shoulder at 50 yards. I could copper plate them thicker with a paint gun...They may work if you drive them slow but I'm all for a quick ethical kill.

Power belts. I think they were designed for CVA. I tried TC shock waves in my optima and it was throwing screwballs.

The one I traded off last month, and I had it for years, had the 29" barrel and liked the 245gr power belt hollow point with both 150 & 100gr charges. If you just going to shoot out to just over 100 yards I wouldn't waste the powder by using a 150 load. And remember if you going to sight it in to shoot out to 200 yards check where it hits at 50 and 100 after you get the 200 yd zero. The only reason I got rid of mine is cause I have gone back to side locks. They are more fun to shoot and 90% of them don't run and the other 10% has gravity helping them. Let the smoke roll and enjoy.

I have a CVA Optima that I bought last year that shoots nice groups at 100 yards with two 777 50 grain pellets and the Barns 250 gr TMZ. I haven't had any loading problems. I tried the Powerbelts and they didn't do as well in my rifle. It consistently shoots 1.5" three shot groups. The stainless barrel is really easy to clean up and the quick release breach plug is a nice bonus.

i shoot muzzle loaders all the time and my optima only liked 100 gr of Pyrodex pellets or 85 gr of 777 loose with a 295 gr PB. I tried a lot of combos but this was the only one that shot well.

I have pretty much gone to loose powder for everything. You get more shots for your money and it is easy to vary the charge. I weigh mine on a small electronic scale.

I went to the 295 SST or barnes 295 the longest shot I will get where I hunt would be about 100 yards if that so I prefer something with some knock down behind it
