What/where are the engraving requirements for a lever action SBR? Also, if a suppressor is welded in place after being threaded on, is it a permanent attachment? Making the SBR tag not needed? (supposing the overall length was right)
 
There's nothing special about a lever action SBR as opposed to any other SBR. The engraving requirements are the same. A little googling should get you the answer on what is required--I don't recall right off the top of my head. I think it's manufacturer (you), city and state, and there are certain height and depth requirements for the letters. You can engrave on barrel or receiver.

If you have a detachable silencer, you need two tax stamps: one for the SBR and one for the silencer. If your silencer is integral and the overall length of the barrel including silencer is greater than 16", you only need to pay a tax stamp for the silencer.

Does that help?

What is an SBR? Should everyone know what an SBR is? Am I the only one who doesn't? Is this a military abbreviation and is that why you guys are familiar with it? I'm a late bloomer to the shooting sports, interested for the past 15 years or so. And I've been very frustrated with the number of times I have no idea of what is being discussed around here. I guess I'll just have to keep asking.

I like lever guns. They're easy to carry and great looking and have a great history. They also suffer from having ammo issues because of the end to end loading. There, that's all I know. I dont' know what SBR is.

Minimum barrel length for a rifle is 16"; measured breech face to muzzle. Anything less than that makes it an SBR and subject to special regulations.
Putting a full-length stock on a Rossi Ranch Hand, for example, transforms it from a handgun into a short-barrel rifle (SBR) and illegal without the tax stamp.
 
I know this is a case dependent question, but if anyone cares to tackle it I'd be grateful.
What kind of energy loss in muzzle velocity can be expected out of a "standard" 30wcf cartridge like Remington's Corelokt out of a 14in barrel vs a 10.5in barrel?
 
150-170gr bullets drop to approx. 1750 fps in a 10" Contender barrel and generally won't expand. It's enough of a difference that Steve Herrett and Bob Milek created the .30 Herrett and achieved the same ballistics with a .434" shorter case.
 
Interesting round reference dwfan, I've never heard of that. Another question you may be able to answer...
I see the avg twist rate for a 30-30 is 1:10-12ish. Do you think this will cause stability issues at subsonic velocities, paired with a short barrel?
 
Going by what folks use for the .300 Whisper, I'd say that's marginal for heavier bullets at subsonic velocities. The Contender uses a 1:10 twist in its Whisper barrel while J.D. Jones advocates a faster 1:9 and even 1:7 twist for subsonics. He designed the cartridge; he should know.
 
Whalerman, the nfa in an extremely interesting subject and you should google it and learn more about it. I was pleasantly shocked when I found out about things I could legally buy just by paying a $200 tax stamp and getting a background check.

As for people using terms (nfa terms) that you are not familiar with, you are currently on an NFA thread.

Interesing nfa topics.

destructive devices (DD)
Silencers (mufflers, suppressors, moderators) of which I own two
machine guns
short barrel rifles (sbr)
short barrel shotguns (sbs)
..........one of the interesting subjects here is why is my Taurus judge (.410 shotshell pistol) legal. Answer, the barrel is rifled.
any other weapons (aow) penguns cane guns etc.

Another interesting angle, is that they don't care how long of a barrel I put on my Contender pistol. If the barrel is 22", its still a pistol. However, 12" or longer, then Tennessee no longer recognizes it as a hand gun for carry purposes.

Some states do not allow some or all NFA firearms. Fortunatly for me, TN allows all NFA firearms. That's more NFA terminoligy, a silencer is called an NFA firearm.

I don't have the data to say conclusively, but one difference is that the 150 and 170 gr. flat point bullets are shorter than the 220 and 240 gr. spitzer boattail bullets that JD Jones was trying to stabilize (at <1000 fps.).

The OP will also have issues with loading density in the cartridge case. The small amount of powder needed to reach 1000 fps. will be about equal to a .38 Special, and will get lost in the larger 30-30 case. He'll have to use some sort of filler to keep the powder back near the primer.
 
S. Hill, I don't have the data either, so you could be right. It might work. As far as loading density, Trail Boss is the answer. According to Hodgdon's, 9.0gr of Trail Boss gives 1197 fps in a rifle-length barrel with a 160gr bullet. Velocity with a 170gr bullet and a 10" barrel should drop well into subsonic levels. Personally, if the velocity was much below 1000 fps, I'd use a cast bullet to avoid the possibility of sticking the bullet in the barrel.

The fact that it's lever action or an SBR doesn't make any difference. All title II firearms must have the maker's name, city and state engraved in a visible location on the firearm (i.e. not under the handguards or grip or something), with the letters being a minimum of 1/16" in height and .003" deep.
