How to start conicals perpendicular so groups don't have flies

[Steel Guitar]

Hello Pards (You Guys),
I'm having fliers because I can't start the bullet square/perpendicular to the bore and yes the t/c maxis are a little larger than the bore. What do I need to do or get to fix this.
Thanks

Are you sure that is why you are getting a flyer? Have you tried a wad under your conical to see if that corrects the problem?

Interesting! No I have not. My experience, limited at best is wads and/or cream of wheat only makes me hungry. But please explain how that will help, and I really what to know. Thanks.

Supposedly seals the bore better and prevents gas-cutting of the bullet base.

If you’re casting them make sure the base is filled out. Then weight them to find out the heaviest one, that is the one with the least flaws. Then only use the ones that match that weight. Any internal void will be off center and can throw the shot. I cast a bullet that weighs 526 grains and only except the ones that are +- one grain.

Is the base of the maxi larger than your bore?
If so, that's a booger for sure.

 

[Steel Guitar]

Yes the base is larger than the bore, AND can I use the felt wads used in 44 cap n ball pisttoles ??

 

[fleener]

Yes, try the wads from you pistol first.

You could use a sizer to get them closer to the size you need.

How many thousands are they over?

You don't want to size maxi-balls unless you're gonna paper-patch or something like that. And if your gun is a 45cal the pistol wads will likely work as good as any. If your gun is a larger bore then the wads would likely just give you another problem.

I have been using oversized wads if using wool. Not lubed, 45 wads in 40 caliber rifles, 50 wads in 45’s and so on. The idea is that by sealing the bore you prevent erosion of the base of the bullet which is a critical component for accuracy.

Sizing a grease groove bullet is not a problem and is very common.

Luber sizers size the bullet and lube it at the same time.

[bubba.50]

Whatever. But sizing a maxi-ball defeats the whole purpose of it.

 

[The Crisco Kid]

Roundballs solve all these problems.

A block of wood with a hole in it that the bullet will barely fit threw could be placed on the muzzle and the slug pushed into the bore. This could act as a guide to use with short starter.

The base of a maxi is always larger to seal the bore and as long as it starts fairly straight it will correct itself when you push it down

 

[rmark]

I think it’s the reverse, the maxi balls are similar to the Lee REAL in that the lower part of the bullet should be a slip fit into the bore with the top band oversize and engraving on the rifling ( the Lee REAL in .45 has bands starting from the ba.452 .457 .462 .467).

OP’s bullets are too big at the base to slip fit and may not be loading straight in the bore. It may be best to try a different bullet before spending money on the tools to resize your current bullets.

Historically elongated bullets of bore diameter were used in target rifles so resizing the current bullets to bore size may work, probably best with a wad under them.

 

[rmark]

I suspect oversized front bands somewhat replicate the old style two part bullets, where the resistance from the harder front section allowed the softer lower section to expand into the rifling.

I'm with Fleener on this one, try a wad under the bullet. It protects the base of the bullet.

Another thing you should put in your post is the load data, bench rest method and bullet alloy. As for a bullet being a tad difficult to start, that doesn't always result in flyers. My competition musket minies don't just slip down the bore and they take a bit of pressure to get them started. The results however-

Size your Maxi Balls down to bore diameter. They will go down straight. Cast them soft. Use soft lube.

 

[Grenadier1758]

The base bands of the T/C Maxi ball should be the diameter of the land-to-land bore diameter. The top band should be the groove diameter of the barrel. Have you measured the land-to-land diameter of your barrel? Have you measured the groove diameter of your barrel? Have you compared these measurements to the measurements of the Maxi Ball? The base bans should slip fit into the barrel to align the Maxi Ball to the bore. The top band should engrave on the lands to prevent gas blow by.

Who is the manufacturer of your rifle? Some are just not optimally designed for use with Maxi Balls or REAL bullets that engrave on the rifling.
