Talked with a rifle builder the other day about sabotless muzzleloaders. He knew all about the Bad Bull rifles but said, if he were building a sabotless rifle, he would build one in 7mm because of the high bc of 7mm bullets vs the poor (in his opinion) bc of .45 and .50 caliber bullets available. He said, he can make the breech plugs, loaders, ram rods, and could build me a custom 7mm ML if I ever wanted one. Have to admit, it sounded kind of cool, especially, since my state is probably the most liberal in the country and has no regulation on bore diameter size for a ML.  I know, the pressure would be high but figure it could be done with the right components. Just curious, have any of you guys thought of having a custom .30 caliber or 7mm ML made for yourself ? |

Which state?
I'd guess the interest to be limited because I thought all/most states had some caliber minimum. Most are bigger bore than Arkansas. Ours is .40 cal minimum.
As a gun, sounds highly intriguing. But you'd be limited to using it during CF rifle season here.

I live in the Bluegrass state where there are few regulations on anything. Hell, there are no poundage regulations for compound and recurve bows here anymore.  Anything goes for Muzzleloaders including calibers, powders, most accessories, and components. |

I am having a Swinglock muzzleloader built in 6.5mm and my state of Virginia has a limitation of .45 for muzzleloaders but I can hunt with the 6.5mm during regular firearms season. It is ok with me that I will use my Savage 10ML during the regular muzzleloader season because this custom rifle will be used for target shooting and only long range hunting which I get very little exposure to here in the thick forests in Virginia mountains.
A 7mm muzzleloader should be cool as beans!

Just as a side comment, I think the 7mm caliber (.284) ballistically returns more bang for the buck than anything else on whitetail deer. No, I don't want to defend that statement.

If my state allowed it and assuming it worked as expected, I'd be all over it  Wouldn't want to be the one developing the loads though... |

Harley Harley, The 7mm caliber has always been my favorite by far and a 7mm ML would be awesome, jmo. BTW, what kind of dog is that in your Avatar ? |

I first fell under the spell of the 7MM when I asked Kenny Jarrett to build a custom CF. He kept pushing the 7MM-08 Ackley Improved. After I gave in and had him build it I became a convert.
AHA, Sag, now we're talking about something significant: Harley is a 65# WireHaired Pointing Griffon. He's what's known as a "versatile" hunting dog because he points and retrieves, on land (quail, doves, pheasants) and on water. He's smarter than I am (or even used to be). Not a mean bone in his body; his only flaw is that he allows my wife's miniature Dachshound to bully him away from his food bowl. I had him flown in from Calgary, Alberta, Canada; I don't know of another one in my part of the country.
Thanks for asking.
Harley

If I were building a 7mm ML I think that I would have some sort of a powder chamber.

8-)The 7mm barrel might work if you are trying to shoot 270 bullets. Might have to have some sizing involved.

Harley, Have to agree with you on significance as I love dogs !  Thanks for telling me about yours, he's a cool looking dog. Yeah, guys, I know it's off topic but dogs are great. |

Sag, if anybody thinks dogs are "off topic", here's a picture of Harley helping to dress a deer killed by a Savage Muzzleloader:  Harley |

I like the sound of a 7mm muzzleloader too. Guys correct me if I wrong but it seems I remember RB talking about pressures increasing the smaller cal you go hince problems with breech plug/ventliner wear extremely increases.

Guys correct me if I wrong but it seems I remember RB talking about pressures increasing the smaller cal you go hince problems with breech plug/ventliner wear extremely increases. I did? Hhhhmmm! Maybe I did, but I was wrong. What I was trying to say is pressure can be made easier the smaller the caliber. That should not indicate that pressure must be made in small calibers. If that were the case the 22 LR would be a high pressure case. What you have to be careful of is not trying to transpose anything you use in a large caliber to the smaller bores. If for instance you assume Imr-4759 is a fine powder in 7mm because it worked in the 50 you're in for a surprise: if you live. A 7mm rifle can be made to shoot most any pressure. This is true of all calibers but specifics must be met to shoot a given pressure with a given weight bullet. Shooting outside the range of specifics will lead to trouble because unlike in 45 or 50 caliber faster burning powders WILL NOT work unless you are willing to shoot very small charge weight. To get the charge/bullet ratio correct for the targeted pressure the correct powder burn speed must be chosen. This would involve a powder much slower than ever thought about in 50 or even 45 caliber. But worry not it can be done if the shooter knows how. |

Listen to RB. The powder that blew my .375 was too great a charge of 4759. It did not blow my face and for that I am thankful but it did a great deal of hurt on an otherwise good Krieger barrel.
The powder itself did not cause the problem, it was an overload of the powder done by an unthinking operator, ME.

Harley, I'm envious; I could use a dog like that to help me dress my deer. Great pic ! |

DB and DW, I remember that deer very well. I was hunting what we call "the pasture". I shot her on the far side of the field. Our rules are that no motorized vehicles can run over that pasture, so I dragged her all the way back. I remember thinking that they were going to find us both dead out there. Because of that experience I bought a plastic snow sled that I expected would make dragging easier. The one time I used it I thought it reduced dragging effort about 0.001%.
