My latest silencer project

It isn't, I bought a nearly-new LH heavy-barrel .308 from Bjorn, swapped the barrel from my HH, replaced the smooth barrel nut with a splined one, and put on a heavy LH bolt handle. I also installed Leupold QD scope mounts and bases so I can pop the scope off and use the handy suppressor-height sights that Savage put on the HH barrel if I want.

Sounds like a great setup...well, 'cept for the lefty part.:D

Oddly, I write lefty but, most other stuff is done right handed. I could write right handed when young but, it feels foreign.

Have you found accuracy degradation or major poi shifts to be a problem?

Honestly I haven't done a direct can on/can off poi comparison with supersonic loads and this particular can on either rifle. What I can tell you is I made no sight adjustments on the M1A with the can and it seems to be shooting right where my notes say it should last time I shot it with this ammo. With subsonics in either system, bullet drop is 5" at 75 yards from the bench, straight down with no windage shift. Believe it or not, accuracy with the subsonic loads is BETTER with the suppressor, go figure?

My choice of 'sided' when shooting boils down to being left eye dominant. I'm naturally left handed but like most southpaws do many things right handed due to living in a right handed world. From the bench I much prefer RH rifles because I can see the "works" without having to roll the rifle over in the bags or climb over the stock. I built the Hog Hunter as a LH because I wanted a bolt-action woods rifle, and while I generally find most RH actions to be no particular bother to operate LH, a bolt-action rifle is one thing that is tough to work from the shoulder in the field while keeping an eye in the glass. This is one reason I like leverguns so much for hunting, they work just as well from either shoulder.

Ian, more than a year late, but fantastic thread. Your detail information on the workings of the suppressors, cone design, etc. was great - thanks much for sharing with all of us :)

I am also left-handed, and since I primarily shoot rifles from the bench, I also find the RH rifles better/easier to use. Centerfire semi-auto's not so much (specially suppressed!) since I get so much dust/debris/crap right towards my face!. The only exception being the 10/22 which is not so bad ;)

You're welcome, Will, hopefully what I tried to explain will assist your endeavor. I took down the utoob vids and deleted my channel because of the policy changes there.

Send in your paperwork with $200 and when it clears in a few months, I think I know someone who might lend you some shop time....

Uhh, well.. to go the trust route & use an attorney(hopefully more smart than me, about that), THEN I could send them off for what I'd like to make. So, lookin at 2k ish all said & done. Learning some of this in advance is priceless, thanks for that.

Hey Ian can you post a better picture/s of the step clip design that you use? I am familiar with the U-clip and have even used a square before (similar to some pistol caliber cans I believe?) but clipping is pretty new to me in general and I have yet to enter a situation where POI shift would be significant so the idea of what you're using^ on my F-class is obviously attractive. Thanks for sharing everything/taking such time to explain- #opensource4life

Sorry, it's all together right now, that's the best picture I have. Its a combination of small u-notch and step clip, works best with a cone of the angle of about 50⁰ plus a beveled stem extending up slightly, and really makes a difference to suppression over either style alone.

Ian, were your clipping similar to mine here:

"when it clears in a few months...."

I have had paperwork in for many months, not exactly sure but I think about 8 or 9 so far.

:headscratch::sigh:

A friend told me that there were FIVE total staff at ATF working on suppressor paperwork.

That sounds nuts, but I have no idea if it is correct. If true, it sounds like intentional obstruction
to me.

I think there are about 20 examiners with a few more having been put on to help handle the 41P backlog a few years ago. However many they had was sufficient for 30 day turn arounds until the demand bloomed along with gun sales and component/ammo shortages following the executive branch party shift in 2008. 41P couldn't have come at a worse time for the already massively overwhelmed and underfunded agency department. Their e-file program is do old I thik it's written in DOS and there is no budget to meet the demand. Typical bureaucracy unable to cope with drastically fluctuating workload and little support from anyone holding pursestrings. The ATF's nfa examination room is far from the only underfunded and overworked .fed department.

In a nutshell, 2-3 week turnarounds in 2005, essentially the same system and staff today as then but look at the workload increase:

They need more people. This is absolutely ridiculous.
What is "the 41P backlog"?

there was a time about 2 years back when they placed a deadline for some new rules they implemented.
about 2 billion people sent in applications right before that [post office stamped] deadline back logging the whole system.

I remember clearly. Two years ago they were going to implement a change to make it a little more difficult to use a corporation to file for an F1. Now, you have to have finger prints of the person acting in behalf of the corporation, so a little more work for sure, so people wanted to get their papers while the could under the old rules.

I was one of those - I spent a lot of money ($1000) doing 5x F1 permits at the same time to take advantage of the no finger print earlier rules. It took them around 10 months for me to get the stamps back. Since there is no expiration date - I can build those 5x F1 any time I want. So far, I have built 3 of them: 22cal (for now in my daughters custom 10/22), a 45cal which I used with my 45/70 or my 460Rowland carbine, and the latest being the 308 cal that I use in my 308 bolt rifle and now in the 300blk pistol I just completed. I still have two more to built :)
