Oh, I see what you're getting at.

My pistol is a G20SF, so I got the single extra-power spring unit for Gen 3 RSA.

Yes, all replacement springs were sourced from Wolff.

The mag springs that I used were the Wolff 10% extra power springs. Got the package of ten 'cause I have many magazines.

Reliability with single-handed operation required that I move to a 24# recoil spring, but also required the use of the extra power magazine spring to get there. Mag capacity was reduced by one, much...

After reading your thread, I have spent the last few days ferreting out the issues discussed earlier.

Eventually, I managed to get the Glock 20SF to fire 100 ''trouble free'' rounds.

This...

Everybody has to be good at something. ;)

Thank you.

I'll take this under advisement and look into that thread (and what your findings were) as one possible avenue of attack.

One thing is for certain. 10mm Glock pistols are...

President Ebrahim Raisi's helicopter didn't crash itself? :cool:

Like you're reading my mind...

At the risk of thread hijack, for which I do apologize, I've experienced far too frequent failures to return to battery even though I've increased the rating of the recoil spring from factory (17...

Yes, Chuck. Good question. Since air is a fluid, albeit one having both very low density and viscosity, the same rules (Bernoulli) apply. The flat surface (meplat) produces a relatively large...

Hmmm.

That is interesting. I've got a Glock 20SF that is giving me fits. That discussion helps. Thanks.

Well, this is welcome news.

I hope that it is signed into law, but won't be surprised if it isn't—weird times.

My annual qual is next month, nice to see improvement in the law.

Same thoughts as you; I s'pose that I need to be "convinced" that this is one that I want/need*.

Those damned forward serrations though! Ugh.

Are we still doing the Cooper 'press check'?

Interesting application of fluid dynamics.

The Hornady design uses a flat nose (which produces a larger/stable stagnation point) which results in the formation of a more symmetric/consistent...

Thank you for the condolences, Shotgun.

Though Hektor was with us only for a short time, his effect upon my kids during that time was a blessing.

Cats?

Yeah...they 'rock'!

Once we've...

GTL basestocks, like those found in Pennzoil Platinum, are highly respected for their resistance to high temperatures and friction reduction.


If I need to use motor oil as a firearms lubricant,...

Those reasons have also factored into why I prefer them. Reckon that I just like an "under dog". :)

Thanks to you and everyone else for the "likes" and sympathy. :cool: The responses and kindness are why I favor P-F above all others.

Love those black cats, man. Gotta 'thing' for black...

Thanks. I appreciate the thoughtfulness. It's hard losing a pet. Harder when so young.

May you see nothing but 'smooth waters' with yours.

Hektor passed away this morning at 8 months of age; feline infectious peritonitis, probably had it when we took him home from the shelter.

Our time with him was far, far too brief. Missed...

I've never been into the AR platform, but were such a ban to occur in my state, I s'pose that I would probably grab two high-quality ARs (I really like the piston-driven HKs), twenty 30-round...

Yes, I agree that his format is rather disorganized. That's a common issue with most of the amateur ammunition testing found on YouTube and other social media.

The short answer to your question...

Thanks for posting the video.

It is nice to see that some YouTubers are beginning to realize that the Clear Ballistics Gel goo is absolutely worthless as a test medium.

Here's another video by...

An interesting application of AT (Alekseevskii-Tate) hydrodynamic model is that the diameter of a projectile's temporary cavity in 10% ordnance gelatin can be predicted using the approach described...

All five bullet penetration equations are available—some at no cost—while others will require a purchase.
