I own 2 Omegas and I am curious where al the QLA animousity comes from. Certainly my guns are plenty accurate to consistently drop deer at 200+ yards. Half an inch extra barrel is not going to do much for your velocity, so what's the deal?
Andy,
I know several people that own Omega's, they shoot saboted bullets very well. The problem with the T/C QLA's is that many are not concentric to the bore. I am not exactly sure of their process, but it is not very accurate. Any time you add another process into the mix, you have a bigger potential to make something worse than it was. Lets face it, QLA's as well as ported muzzles on muzzleloaders are not there to increase accuracy. I was hoping that the X7 "King of the Mountain" would come without the QLA, I would own one if they had. I thought T/C was finally making a Colorado conical chucker, but that was not the case. Several have had their QLA's removed from the barrels. It is not a big secret that gunsmith's are chopping off QLA's, re-crowning barrels, and shortening the ramrods on T/C's.
The conical, as you know rides directly on the rifling and does not have that plastic cushion like a saboted bullet. The QLA definitely has an effect on them, I don't know if it is blow-by, but it upsets the accuracy. The sabot base expands as it leaves the bore and doesn't seem to be as effected by it.
All I can say is, get some good conicals and try them yourself. Some of them will shoot them OK, but my bet is that it will be less than half will do it well. Only you can know if yours will shoot them well, by shooting them and finding out for yourself.
A good clean true crown is going to give you the best accuracy, anything else (porting, false muzzle) only has the potential to take away accuracy IMO.
