HI All,

I talked with Marshall today as my initial foray into this forum.

Marshall: Richard Baxter, Puritan "...better than I deserve but not as good as I hope for."

To bring everyone up to speed I asked Marshall how to get a projectile for fire lapping a 25 caliber muzzleloader that I am building up. Marshall had a brilliant idea: use an airgun pellet!

Well, it turns out that there is an interesting pellet out there that might be an idea fit with a simple modification. I would like to know what you 'fire lappers' think.

Here is the website:

Thanks Marshall and all in advance for your insight/opinions.

Coram Deo,
Brian

Hey Brian, welcome here.

The rules are simple: be nice and join in!

I can't say I know anything about firelapping, but it seems as good of an idea as any. I actually didn't know airgun pellets came in any size other than .22 or .177. :$ Don't hold it against me though, I'm Canadian.

Again, welcome, and I'll see you around the forum.

They would be pretty soft but if Marshall recommends it, I don't see any downside. Good luck!

Here is a link that is somewhat related. I was reading somewhere about .25 muzzleloader barrels being sold but sure cant recall where. if I come across it again i'll let you know. A barrel liner might be another idea.

If the barrel had a rifling rate of twist for lead roundballs (whatever that would be in .25 caliber) you would have to take into account that bb's dont use any patches ( bb gun barrels are smoothbore) thus they would be an off size. Interesting but I should not have replied because i dont know much about zimmerstutzen rifles at all. If you used a bit smaller pellet with a paper patch that might work but seems incredibly meticulous since they are so small. Random thoughts.... I'll be quiet.

BBs are .177 caliber. Pellets can be .177, .22, or larger. Pellet rifles are almost always rifled, not smoothbore. But rate of twist might indeed be an issue, depending on weight differences.

A 25?? Sounds like an interesting and unusual caliber. Should be a fun little shooter!

 

[@bullseye]

There are .25 caliber lead balls (bb's). I looked them up in the search engine. What kind of barrel are you using? Groove depth is a factor to consider too. I seriously doubt you could use paper patches on air gun pellets because of their shape. I dont know about sizing them. I'll leave comments to someone more knowledgeable. It is very interesting.

A #4 buckshot is .240. One shotshell of #4 buck will give you 24 round ball to shoot. You can also buy #4 buck in five pound bags ..... one bag would give you years of shooting ammo.

Good idea. Patch thickness calculations are here.... http://members.aye.net/~bspen/math.html

Hmmmm, sorry I misunderstood the question. You want a projectile to fire lap the barrel. I think there is a tutorial on fire lapping in another Beartooth section. Don't know if it would be applicable for a salon bore barrel though. You could maybe pour a slug to hand lap but again I don't know because of such a small diameter and shrinkage and all. I would think that hand lapping with steel wool or scotchbrite or whatever is used might do the trick since it is such a small scale. I kind of think lapping should not be done unless it's really needed. I appologise for my ignorance. I knew I should have kept quiet.

The projectile shown in your link doe's look suitable for paper patching. Man! I really should pay more attention.
