While there may always be "room for improvement" not every improvement may be an advantage to the human operator. It's nice to bed the barrel, and worry about the stock rubbing, or pressure from the ramrod..., on a 1000 yard gun that would really be a factor. Are you shooting it that far?
The only accuracy "advantage" in an inline is the ability to throw the projectile accurately over a longer distance than its traditional ancestors (imho). The best method for this is the sabot, but if you are limited to modernized conicals a-la the CVA powerbelt..., you are now closer to traditional range, OR you are mounting a tang peep sight or mounting a mil dot scope (or perhaps messing with scope adjustments when in the field).
The Civil War rifles threw heavy conicals over long distances,
with adjustable sights, at standing human targets. Before I'd worry about improving the barrel accuracy, I'd get a load that was accurate close, and a sight system to extend that accuracy beyond a football field. When I got it close to 250 yards and accurate enough to hunt, then I'd worry about bedding, and stock pressure and ramrod pressure.
Otherwise it's an academic exercise, which can be lots of fun I admit
, but are often not practically applicable. (OK I will also admit I have tinkered with many a long arm to see how accurate I could really get it to shoot, and I wasn't competing or anything..., I was just curious.
) Meaning, I know a fellow who uses his own loads for his rifle, and at the range he can put bullet after bullet in the same hole at 200 yards..., but he can't get anywhere close to that shooting it without the bench and a stool. Put him in the field, and all that "accuracy" gives him fits (barrel heavy, stock doesn't fit him right when he's all that is supporting it, high magnification scope "dances" all over the place, and he's not used to a tight shooting position in the field).
In fact he doesn't use his bench rifle for hunting.
Another person at the local club has a Remington bolt action carbine in .308. Pencil thin barrel, and it doesn't group well at all at 100 yards. BUT the first shot from the barrel is extremely accurate. (Additional shots heat the barrel and he throws a "string" on the target)
He could worry about the wooden stock changing pressure on the barrel as the humidity and season changes, he could free float the barrel and bed the action, he could have a better barrel installed, and he could have an after market trigger (maybe a Timney) installed. AND he wouldn't take more large game than he does now, for all of those modifications really make a difference at a match nor at very long range..., not necessarily on the first shot for most folks.
