Tl3 shouldered barrel slop

[plinkin]

Just curious if anyone else's barrel to action slop is as much as mine. At one full turn off the shoulder the action moves 1/8" at the end, when the shoulder is threaded half way off the action ( roughly 3/8" space from the shoulder to the action) the end play slop is 3/16" close to 1/4" of movement. Does someone have any experience with this? Thanks.

My prefit bbl threads for my origin were looser than I would have liked/expected.

Shoots great when torqued down though.

It's alot more slop than I would have guessed and care for. I'm afraid the threads are going to start "folding" or wearing ruining the action.

Where did your prefit come from if you dont mind me asking?

 

[ZEROGUY]

Yeah I didn't have that worry with mine.

Maybe something is up with it then.

Do you have calipers handy?

 

[plinkin]

Yes

PVA, CBI, Savage Factory bbls, all have been on my origin, all had about the same amount of slop as I recall.

Barrel threads are 1.058 to the outside the action threads are 1.007.

I don't know what the ID threads of the TL3 should be, but the action being out of spec is extremely improbable.

1.055 is the diameter of a small shank savage, I would think you have enough bite on your threads.

But I'm not an expert, hopefully one will chime in.

this "slop" is more apparent in 20TPI actions. ive taken our pre-fits made to a minimum 3A standard and screwed them in a receiver that's in spec and there will be more play than a fitted thread. Ive not been able to make a correlation between thread fit and accuracy, but if you think its a safety concern then you should get it double checked. perpendicularity trumps thread fit in the accuracy dept

Thank you for taking the time to post, do your prefits feel like what I'm describing? This is from a reputable company but like anything that's new to me I tend to pick at things that stick out. If it's normal I'm fine with it. Also on a side note if you were to make a shouldered prefit for the tl3 in a standard 308 Winchester would it be able to chamber 175 fgmm? This is another issue I'm having with this barrel action combo. I have to set a 175 smk at 2.730 oal or else it in the lands.

You’ll probably be fine OP

my old savage just got its third barrel and it’s sloppier than a pornstars butthole after a 50 man gang bang is it torques up fine.

Those barrels threaded up bank vault tight in my nucleus so it’s the receiver and not the barrel tenons.

I think your deflection amounts sound normal to me, but realize that for me, figment is a feel , not a measurement
Pretty sure you'll be fine
Both 168 and 175 SMK are 2.82 -2.83 On the lands with my std reamer. Check your measurements, 2.73 is way too short

Ok thank you, regarding the 175s that's what I was thinking.

I agree with Bugholes, you’ll be fine. If you want to check it yourself, and learn a bit about V form threads, buy yourself some thread wires, and learn to measure pitch diameter. You’ll need a micrometer for this. It’s the critical dimension for the thread, not the major diameter( which you already measured).

Go to YouTube and look for “measuring pitch diameter over wires”.


A thread wire set can be had super cheap.

Spife will probably be along soon with a nice diagram.

Ive never thought there was too much “slop” in any of the shouldered TL3 pre-fits Greg (Bugholes) has spun up for me...~8 barrels now!

That slop is actually thread clearance. There has to be some sort of clearance or you'd never get them together.

I torque mine up to 80-100 ft lb and they never, ever move.
