The other day I got a urge while in a store and ended up coming home with a .50 caliber CVA Optima.  It has the speed breech, stainless steel barrel, fluted, and fiber optic sights.  Not that I needed this rifle, but need never really fit into the equation.  Wanted is more of better statement.  Anyway it came home with me.




I had it out yesterday just to see how it functions.  And try some basic loads is all.  I was shooting Pyrodex RS and BlackHorn 209 out of it.  Even though this rifle does not have the BlackHorn 209 breech plug, it handed the powder just fine.  But I am not really sure it will be the powder I want to use.  I like Black Powder.

I was shooting some 240 grain .430 XTPs in Harvester Crushed Rib sabots and it did pretty good, but the powder charge needs to be played with.  Anyway, I was wondering to the Optima owners on this forum...  what loads do you shoot out of your rifles?  I am not interested in shooting Powerbelts, although today when I called CVA to get a DuraSight mount.. and asked them for a recommendation of a load.. they suggested 100 grains of powder and a Powerbelt.  Strange they would do that.  Maybe since they sell them the have an interest in Powerbelts.  But I am more interested in what you shoot.  And I will tell you up front.. I do not shoot magnum loads.  I see no need for them.

I had some Weaver bases and a $19.99 Simmons ProSport 4x32 scope around the house and mounted that.  But only until the new mounts and scope come.  What mounts are you using on your Optima?

I shoot 100 grains of pyrodex and 250 superglide sabots in mine and they do great. My optima does not like powerbelts at all. that load has served me well for years. the only change is one year I used 250 grain hornaday sabots they did ok but not as good as the T/C superglides.

Thanks.. I tried some 348 grain Aero Tip Powerbelts out of it yesterday but was not too impressed. CVA told me to try 250 grain AeroLite Powerbelts. But at $2.00 each they can't be serious. I was also told that 300 grain and 250 grain XTPs shoot well out of the Optima. And first hand knowledge with them?

I shoot White Hots and Powerbelt Aero Lite's with a very tight 3" pattern at 100 yards. This is the only thing I have tried although.

That was the exact load that CVA recommended to me.  They are kind of expensive.  How are they at taking game?

I have some Pyrodex RS pellets and some Parker 275 grain Extreme.. they might do good then. I will have to give that a try. Thanks for the heads up. What scope mount did you go with.. or your son go with? I purchased the DuraSight one piece with built in rings. It is what was suggested. And I will be putting a 3-9x40 Cabela's PowerHorn Scope on it.

My rifle doesn't seem to be picky as to what I put thru it.  I have some 245 grain powerbelt aerotips, and some 250 grain Hornady sst/ml sabots  that I have been using.  I have been using 100 grains of Pyrodex pellets, or 95 grains of American Pioneer powder behind them.  They all shoot 2 to 2 1/2 inch groups at 100 yards.

The optima I had, (sold it due to its weight) liked powerboats and 100 grns 777. One thing you may want to watch is, make sure the breach plug is tight. I left mine just a bit loose once and missed an opportunity at a very nice 4 1/2 year old 8 pt buck. It functioned fine in the house,( and warm) but once it got really cold the hammer would not stay in the cocked position. I had a nice buck broadside for several minutes and could not get the hammer to stay back. After he walked away I opened it again and got about 1/4 turn tighter on the breach plug and it functioned fine. That was on opening day, it took the rest of the season before I got another opportunity at him. His head is now on my wall. So, the story does at least have a happy ending. lol Mine was a real good shooter too, just for the record.

I upgraded to a 3-9x40 Cabela's PowderHorn Muzzlelaoder scope. Very clear and the glass seems great. And with a Dura Sight single base mount and ring its a nice solid combination. I was shooting 90 grains pf BlackHorn 209 out of it the other day and some 300 grain Hornady XTP and the results looked pretty good.

Cayugad as you know I have a love affair going with those Hornady XTPs especially the 300 grain offering. I get very good accuracy and my freezer has the terminal results of these bullets. At least the ones that follow me home. For me, if I do my job the rifle and bullet will do theirs.

I have a older 50 cal CVA Optima and I used the 245 HP and AeroTip Powerbelts with two White Hots. The only problem I had that there was no blood trail. This year I used the new AeroLite Bullet 250 grain and it worked great and the blood trail came out on both sides of the deer. At the range AeroLite Bullet 250 grain gave me two inch pattern at 100 yards. Ive have taken all my deer with powerbelts, but from now on I will use the AeroLite Bullet 250 grain.

I have some 180 gr sabot that I want to try in my Optima. Here is my thoughts on this and I may a little off my rocker. If I use this lighter bullet thereby reducing my powder load can I accomplish the same thing on the deer, as lighter bullets are used in high power rifles and I know the velocity will be lower but seems it should still work or are my squirrels running rampant

if your using loose powder.  You could probably play with the powder to keep up the velocity.  Howerver. keep in mind that with the lighter bullet.  You may not get penetration that your looking for on game. You may also have to rezero the gun just like you would with a centerfire with a different bullet weight.

I have been battling a cold. You know, runny nose, cough, and chills. But I really wanted to shoot. And yesterday I felt pretty good. It was 28 degrees so it was not cold out. Very little wind. And the trash needed burning. So this was the perfect opportunity to shoot as I could monitor the burning trash (something I always do) and shoot also. I wanted to shoot the optima again. I wanted to see if the Cabela's Powder Horn scope would give up the ghost like the last one. Nope.. it worked perfect. The old one really broke in a minor manner, but broke is broke.  So the new one took its place.






This was how I defeated the sun light today. The sun was at just the right angle on the horizon that looking through the scope, it washed out the lens because I was peering into the dark woods. Yet when I shaded the side of the scope, all was well in the world. So I decided.. lets create our own shadows. Worked like a charm.



I started out at 25 yards. I remembered from the last outing with the new scope that it shot high at 25 yards but really high at 100 yards. 

Shots 1-3 show that at 25 yards.. the rifle was dead on, Group wise. That is the three shots directly above the bull about two plus inches above dead center. About where they were the last time I sighted in the new scope.  The only difference this time was I increased (at the suggestion of a forum member) the BlackHorn 209 powder charge to 100 grains instead of 90. I really don't see a big difference and it made little difference on the range either.

So I ran the target back to the 100 yard barrier. Range finder told me it was 91 yards. That is because I moved the bench up further towards the back door of the house, out of a snow pile. Then I shot 4-6 . The reason you don't see shot six is it was a POOF and I mean as soon as that rifle went off my mind thought.. what the HELLO... is going on here? That bullet hit approximately ten inches low, a little to the right and key holed. I had used the drill bit after the third shot, just to be fair to the distances. For those that are not aware of the characteristics of BlackHorn, it likes to carbon up the plug.  So you take a 1/8th drill bit, put it in the breech plug and turn it by hand.  This scrapes the carbon out of the fire channel Shots 4&5 sounded fine. But #6.. as soon as it went off, I knew that something was wrong.

But I had a pretty good idea that at 91 yards the rifle was hitting 4 plus inches above dead bull. That is way too far out of control. So I made an adjustment to the scope. I want this to shoot good at 100 yards. I never counted the clicks.. I just knew at that distance it had a lot of clicking to do.. and I guessed.

Shots 7-11 showed me I made the right amount of adjustment. For 91 yards a under 2 inch group, I will take any day of the week. This optima is really starting to show its true accuracy colors.

I then saw my shooting sticks resting against the house and decided to try them with the few bullets I had left in the box. So I brought out the sticks and rested them, still seated at the bench, but against the bench table. Which is an old weight bench I kind of customized to make a nice shooting portable platform.

I had 5 bullets left and shot five times. They are marked with just a slash. Funny that I shoot a little to the right off shooting sticks, but on a good solid bench rest they are in there. Well I guess if you really want to examine the bench rest shots.. the are a little to the right also. It might have something to do with trigger pull, different body posture, who really knows. But for off sticks I was happy. And out of bullets I might add. So I decided to call it a day. I am wondering that because of the change in posture, and the unstable platform of the sticks VS the bench, I might have crowed the trigger.  But I was still pleased with it.

Why #6 went POOF I still do not know. And to key hole to boot. Funny was, I never used the drill bit, but just kept on shooting the next ten shots and never had a problem at all. Also I never swabbed the barrel the entire time.

From what I'm seeing on the target.  You have a good group going on.  What I would do is.  Ok, when your out hunting.  Your not going to be shooting off the bench.  But,  You'll probably going to be shooting off the sticks. If your hiiting where you are right now off the sticks.  You'll probably do it when shooting at game too.  I would probably adjust my scope 3 or 4 clicks to bring it closer to center.  Off the bench.  You'll be 2 to 3 inches to the left.  But, off the sticks you should be right on.  I hope this makes sense to you.  I do the same thing sometimes.
