Latest BP project

1884 trapdoor, .45-70 in a Hawken stock.

That looks pretty good!

A Gemmer! I LOVE those things. I was eyeing a barreled action online to make one of those, but I hesitated too long. Nice job!

Beautiful rifle ... all it needs is a ramrod -er- wiping rod to be complete.

 

[EvilGenius]

Just ONE picture!?

 

[BHP FAN]

I know, right? Leaves ya hungry, and wanting more!

 

[Archie Otto]

Well, I didn't want to overwhelm the site with a bunch of boring pics.

 

[Panzerschwein]

I like it!

 

[bannockburn]

Pretty neat conversion. I like it a lot.

 

[kBob]

That there is right nice looking.

Really well done inletting it looks like as well.

Don't look too close at the inletting :banghead: I struggle with the real close lines. Pictures from a distance are best and if I can keep the gun moving while ya look at it that helps a lot too. But I'm trying......

 

[Patocazador]

Personally, I think it's a mistake to try for an exact fit when inletting. The different materials expand and contract at different rates with temperature changes plus wood absorbs water to a degree which makes it expand. When hung above a fireplace for decoration, the wood dries out, shrinks, and cracks.
Very close tolerances exacerbate any problems.

Well it is nice to see you had all those photos ready to go in case we asked.

Way beyond this nimrod.
45/70 will it be loaded as a 45/70, that is 70 grains of black.

The full length pics were already saved but I went and took more of the nose cap and lock. With a cell phone it only takes a few minutes to take pics, send them to email, upload to photobucket.com and then copy them to forum. When I can copy directly from my brain to the internet then virtual ubiquity and pansophical awareness will be achieved and the ethereal universe will be mine, MINE I SAY! BWAAAHAHAHAHA!!

My load uses 62 gr. of FFg and a 500 gr. cast boolit (.45-62-500). I believe the original load was .45-70-405

Must kick like a Missouri mule.

The extra 95 grains of lead take up the space with the reduced powder charge or it doesn't matter? Hear a lot about "air space" with BP loads, can't figure out why as it makes no difference in smokeless.

Very nice!!

Archie, good job!

Main difference is the original used balloon-head cases, vs modern solid web cases. Airspace allows the pressure wave to move faster, slamming against the bavk of the bullet. If it hits before pressure has built to the point the case has expanded to release the bullet... ringed chamber. More prevalent in muzzle loaders as there's no case releasing the bullet.

So bottom line, no airspace brass cartridge or chamber. I have observed that general rule without knowing why.

I got the loads from SPG"s primer by Mike Venturino and see no need to change. The lighter bullet loads do use more powder.

To me she don't push all that hard using black powder loads. My .54 muzzleloader with maxi-balls and 100gr. of FFg has a noticeably heavier recoil and neither of those comes close to heaviest .45-70 smokeless loads for the Ruger #1.

I don't know the science behind the "air gap" warning but I am willing to take the "experts" word on that issue, for no other reason than to avoid the possible catastrophic results.
