Not a lot of information to go on there. Is this a new rifle? If it is, some of them need to be broke in. Get a batch of maxiball and shoot then through the barrel with about 70 - 80 grains of powder. Just have fun with them and the accuracy might surprise you. After that take some J-B Bore Paste and scrub the barrel to remove any lead fowling, copper or other impurities in the bore. This will also help to break the bore in.

Next is examine you powder charge and the projectile your shooting. Many rifles are real fussy about powder charges and projectiles. What powder charge are you shooting and what projectile? After your certain the rifle bore is broke in, and clean try some 245 grain Powerbelts with 100 grains of loose or pellet pyrodex and see how it shoots. You might also want to try some of the different sabots out there like 250 grain shockwaves or 240 grain XTP's again with a 100 grain charge and see how it shoots. Be sure and swab the barrel between shots to get your best accuracy.

If you have tried all of this and it still will not group then contact CVA and describe the problem and what you have tried to do to make the rifle shoot well.

How many rounds have you put through the rifle? If it is brand new it may need to smooth out the rifiling in the barrell. Check out this post

My brother in law has the Optima Pro and is using 90 gr. of Pyrodex RS and a 295 Powerbelt AeroTip bullet with a Winchester 209 primer and has decent groups at 100 yds with open sights. Hope this helps.

The rifle is in its second season. I have shot atleast 60 Powerbelt 245 HP with 100 Grain of Triple7 powder using Remington 209 primers. All this just trying to get a group. At 50 yards it is from 2 o'clock to 6 o'clock without any scope adjustment.

WOW... I guess you're at square one. You have to try some different projectiles. Perhaps this is a rifle that hates heavy loads so you might have to lower the powder charge to 80 grains. I have heard of people shooting Shockwaves with good results. Sorry to hear the rifle is giving you fits..

I've got an Optima and it shoots well, but I had a cheaper version of the CVA hunterbolt that did not shoot well. The reason was that the scope rings were loose. Maybe your guns shoots OK, but your scope is off. Just a thought! Try taking the scope and putting it on another gun and see if it shoots well.

the optima is guaranteed for life. i would send it in and let them figure it out if youve tried everything. last ditch effort i would clean it real good and try the jb paste. try 2 or 3 more different bullets but it shouldnt be that fussy. make sure you are shooting using a solid rest. if you can let some one else shoot it just to verify.

I had the same problem with the 245g powerbelts,they shot great through my Kodiak but were junk in my Optima.Was shooting 100g Pyrodex.I switched to 240g T/C Mag Express Sabots with 100g of pyrodex and it shot great 3in groups at 100yds like it so much didnt even take the Kodiak out of the cabinet this year.Give it a try should be great for you.
