TC Maxiball In CVA Inline

[mardrobe]

Hi.  Walmart was clearing out TC Maxiballs for $1.00 a box, so I bought 10 boxes of the 320 grain.  Does anybody know the diameter of these things or tried shooting them in a CVA inline like my Buckhorn?  All I have used in the past were Powerbelts.  I know you're supposed to use .490 roundballs for a 50 caliber, but I don't know on conicals since they don't use a patch.  I also believe that they need to be within .010 inch of the bore diameter to be legal.  Thanks for any info.

Is yours a .45?

i had an Winchester X-150 50cal that shot the 350g maxi's all day long. It loved the things.

I stopped using them due to 2 lost deer and no blood.

I tried using them in my Encore 209x50 with no luck. Not sure of the twist rate in your barrel, but mine was 1-28.
Just couldn't get mine to group. Looked more like a shotgun pattern at 50 yards.
Won't know till ya' try.

I don't know the twist of your CVA but the key to shooting maxiballs in a fast twist inline is to use light loads.  Ideally you would want a 48 twist barrel but if you slow them down (70-80 grain charges) maybe even lighter they will normally do alright.  The problem with the fast twist barrels is that the lead is too soft and when driven fast thru a quick turn barrel the bullet actually gets shaved by the lands instead of imprinted and you loose stability.  Slowing them down usually solves the problem.  I shoot the 370 maxiball in a couple 28 twist inlines with good results but I'm shooting them over 60-70gr of pistol pyrodex.  Also the maxihunter is softer lead than the maxiball so if that is what you bought it may need to be slowed down even farther.  Those conicals were designed to be shot thru a barrel with deeper rifling than what is normally found in todays inlines, they can work but it will probably take a little experimenting.

That totally explains why mine wouldn't work. I always tried to push them with 100-120 grains of RS.

No im sorry TN_JUNK but your problem was your rifle.  Have the QLA cut off and you will more than likely be able to shoot conicals with good accuracy.  A White rifle will shoot a conical beautifully and it has a 1:24 twist, Some i believe were even faster.

1:28 twist is excellent for sabots and conicals.

TC just cant fix their QLA problem and they suffer greatly when loaded with an all lead projectile.


Buckhorn has a 1:28 twist.

Not all T/Cs are this way I would like to add. Some T/C's with the OLA shoot conicals very well but the majority don't. If I were you I would try the lighter load but you will get mixed results. I wish T/C would offer the OLA as an option for those of us that want to shoot conicals.

The white rifles are actually designed to shoot conicals, their rifling is deeper and their bore diameter larger than the T/C.  Most T/C inlines have tight bores, I have 2 that slugged .495 and .498, most whites are .503-.504.  Couple the larger diamerter and better rifling and the conical obturates into the rifling upon firing and since the rifling is deeper its less likely the bullet will skip or shave.  The shallow T/C rifling especially with a tight bore results in bullet deformation and slipping/shaving and the faster you run them the more likely it is to happen.  White and T/C are not an apples to apples comparison, and there is more to consider than twist rate between the two when shooting conicals.

My winchester slugged .501 along with a cva staghorn i had. Both shot conicals excellent.

Now have  a .45 Apex thats doing well with conicals. I just keep running out of bullets before i find the right powder/charge it likes.

12 shots the other day with pyro select all to find out that it prefered pyro p!
