Will find lots of opinions on most any subject on forums.
I certainly do agree with
Kmcmichael on sights & eyesight deficiencies. Many sights on repros are ideal for short range hunting but way too coarse for shooting tight groups on targets at 100yds & especially if your eyes are not the best.
During my 60+ years of owning & operating M/L store fronts & even more years of hunting & competing it was great fun testing almost all brands of factory mfg. repros that surfaced from the 60s & on.
Most customers starting out reserved purchases of more costly custom firearms with higher quality barrels & components until they became hard core .
During that period I principally collected, hunted & competed with original rifled English & European hunting & target rifles & pistols mfg during the 1700-1800s because the quality of steel & tight group accuracy obtained by their barrels & the deeper & faster rifling styles were tough to beat.
Most of the original & most accurate rifles & pistols I've shoot have close to one-turn in the length of their relatively short barrels.
Example; my orig. tack driving .70 cal. Jaeger has as I recall has .014 deep rifling with 7/8 of a turn in it's 29" long swamped barrel.
With it's fairly fine & forward set express sights & 80 grs. of 2F it has no problem providing excellent one shot kills on big game @ 200 yds.
When TC first came out with their version of the Hawken Rifle it was a big hit as they mimicked the 1in 48"rate of twist found in many original Hawken rifles.
However due to much shallower rifling depth of about 008 & less that is also found on many of today's modern factory produced MLs, these barrels require a slightly oversized RB dia. & thinner patch combo to shoot well & prevent having the ball skid & patch cutting especially with heavy powder charges..
As most vintage forum members will recall Thompson Center & lee Molds in the early days recognized this issue & came out with various bullet mold designs that worked very well in barrels with shallower depth rifling for hunters in states that allowed ML hunting with bullets.
All forum members are correct in that ML barrels with longer rates of twist & shallow depth rifling are less picky to get to shoot reasonably well.
Those of us who strive for top notch accuracy & the tightest groups are usually any firearm forum's trouble makers .
The makers of barrels for our Civil War our era mini-ball shooting rifles & carbines were sharp cookies.
They choose shallower depth rifling for shooting bare projectiles because the shallower depth rifling produced less fouling & more rapid loading & led the way to development of those un-mentionable cartridge firearms
