That a big problem !

And I fear "regular" ophthalmologist won't be of any help but a shooters specialized ophthalmologist.

For example in Paris, there is an optician for shooters (http://www.lunettes-de-tir.com/). I will see him for a better understanding of my problem. I won't come along by myself.

In addition, lights (gallery, target) could be very tricky ...

Where I'm practicing shooting, targets are outside and the indoor shooting gallery is badly illuminated ; not so easy to see the gun sights, in particular on our muzzleloading guns !

As you say, the best would be to get a full set of brand new eyes !

I'll keep you advised of the solution I'll find with that optician. Hope it would not be too expensive !

Philippe,
Have you ever floated a ping pong ball over a hand held hair dryer? Round ball is easier to make accurate out of a percussion revolver just like a ping pong ball centers itself in the air stream over the hair dryer. When a flat based bullet is used the problem of achieving alignment comes into play. A very small amount of misalignment allows the bullet base to create a sideways jet of gas, an imbalance in thrust that sends bullets in random directions. The spherical backside minimizes the effect.
When "conicals" were in common use target accuracy was not the main concern. The military needed revolver bullets that would go through thick clothing and still inflict adequate damage.
Making a flat based bullet accurate requires that it be fitted to the revolver. Misalignment has to be minimized. And that can be a problem when most available percussion revolvers are made with chambers smaller than the groove diameter of the barrel.

Yes, I understand that ”¦ but ”¦ my shootings inaccuracies are not while using round balls but heavy conicals ”¦ with my Dragoon at 50 yards.

Round balls work pretty good in all of my revolvers (R&S, Dragoon and Remington NM 1858). :wink:

Conicals work just as fine in my Dragoon until 25 yards. But not until 50 yards as I do suppose the spinning movement has lessened.

So the chambers diameter is probably adequate to fit the grooves ”¦ even if I have made no measurements (what I should do one day nevertheless).

But as I said in my previous post, my eyesight is decreasing badly ”¦ so I must solve that first before attempting anything else. Not to be sure of the aiming point because everything is fuzzy is not a good starting point for further trials ! :idunno:

When my shoots will be in a 5 inches circle at 25 yards, I'll probably look forward for improvement in using the most perfect round balls I will be able to cast.

From another hand, I'm always trying to make my RBs as round as possible ”¦ but not perfectly. I know I would have to weigh them too ”¦ but that takes so much time ”¦Â !

So to summarize : before going further, I should find appropriate shooting glasses ! :shocked2:

All the best.
