Standard pellet to a HOLLOW POINT ... it can be done !

[darkcharisma]

Scott, your waiting on slugs, and i'm waiting on NOE to make molds. 

Grrrrr!!!

Me too Mike, been waiting for the 223-38-RN-CC1 to become available. I wonder who else is making a similar one?

[Motorhead]

Woo WHOOOO ….. just received a few 100 pre-production NSA slugs off the high speed machine.  12-15-18-21 grain hollow points ALL with dish bases.

 

but it's hot "dang" HOT right now and not sure when I physically can endure being out in this heat and do some testing …. too be continued

[KnifeMaker]

Will be watching!

I used to take RWS Super-H Point pellets in my 1377 and LIGHTLY nick the tips with a razor blade. Maybe 1/32 to 1/16 inch deep, just deep enough to score the flat section at the base of the hollow point cavity.

When fired from my 1377 into Grackles & Starlings that constantly stole my grandfather's dog's food, they would open up into 4 "arms" with sharp tips (a lot like the Talon ammunition for firearms). IF they exited, the exit wound was always at least 3/8" and the pest was always planted hard with a single hit.

I want to try the same in the soon-to-be-mine 392 on the chippies that are tearing up my mother's garden.

I'd love to see/ read of more results with the DIY hollow pointing and slitting! 😄 

Thanks for the ideas and thinking outside the box! 👍🏼👍🏼 


I guess I have 2 shooting scenarios where I'd like HP to expand better than they do. 



🔶 What we have:
Many HP require very high velocities to do so (because their HP cup is narrow, or they are made from harder lead).

Your methods of deepening the HP cup by drilling it deeper and/or cutting slits in the cup sounds feasible — but I cannot help but think that the precision must somehow suffer... 😟

So, I'd guesstimate that DIY-deepened HP pellets and DIY-slit HP pellets will only shoot with reasonable hunting precision out to say 20y.



🔶Shooting scenario 1: 
In my 30FPE gun (.22) — at that range — I'd get most of the HP to expand anyhow. So, no gain there....

➔ But wait! I always wanted to "explode pigeons with a puff of feathers"! (words forum posters — not my own... 😄). 
So, your methods give me hope that I could achieve this — at 20y ranges — and without using slugs that will fly on for a dangerously long mile in case I miss, especially on angles shots(!).



🔶Scenario 2:
I also shoot a sub-12FPE gun (.22). And at that power level I have resigned myself to never get any HP expansion — ergo, I don't shoot HP with it.
Now, if I did take a very wide HP (like the H&N Crow Magnum), and did the slit treatment and the HP deepening treatment... 🤔  ➔ It might actually expand some.... 😄 

Of course, again only usable for short ranges, say under 20y.

And it might not expand — because the MV is abismally low — 540fps — and much less on impact....



➔ Oh, well, the 20 yard feather puff is still something I'd like to try. Thanks for thinking outside the box and posting about it.
I need to find some time to go to a cow corral for some P/TESTING. 😄

Tried something new. A blatant copy of Eric's work at hollow point mold services. For my own personal use, sono infringement.I will call Eric and send a pic of two.


Mike

[KnifeMaker]

Results at only 690 fps. 60 yards.

[KnifeMaker]

Dropped from 39.8 to 35.6-8 grs.

[Back_Roads]

 Those look like they would be wicked  I was thinking of trying that on a Lee 357 mold, after getting some of NOEs versions with single HP option.

[HunterWhite]

Dang those look good Michael!

Hunter

[bear air]

Those do look wicked Knife. And to open up like that at such low velocity... wow. Good luck testing Scott. I hope the 15gr ones do good since that's the ones mine likes. Although it is completely different than their hand crafted ammo.

[Motorhead]

Well ... with H&N just recently DISCONTINUING the Sniper line up there becomes zero point in continuing to work at this further. 
TAPERED / DIABLO skirt conventional pellets are too difficult in holding, so thinking we're done !
NSA has there .177 cal slugs now off the high speed machines as of earlier this week.

[KnifeMaker]

Wow! that's a shame. The heavy Sniper is my favorite factory pellet for hunting scorpions with the pp-700. But I shoot slugs and now cast pellets in it as well. All are accurate.


Sure wish I knew what magic they used on those barrels!  

Mike

[K.O.]

That really does  bite both my BSA Buc and  Diana Storm .177 love the Sniper Magnums..  

I should have stocked up...

[Frank in Fairfield]

Just wondering....
Do these “slugs” cost more than .22lr High Speed Hollowpoints?
Just wondering...

[mrbulk]

Bored ... waiting on NSA to make affordable .177 slugs 

Been shooting the .177 Bottle-Rauder the last few days after Rabbits .... 2 so far.  Issue is at @ 1050 fps the H&N Sniper magnums go right threw like an Ice pick !!  While head shots anchor them well enough, Body shots DON'T !!

So for a few hours today fiddled around on the LATHE being able to HOLLOW POINT modify some pellets 
The lathe jaws allowing holding pellet by the waist while using a starter drill to make a hollow point into the domed head.

Starter drill makes an .080" hole while drilling down .100" to make an aggressive hole that should open up nicely !!
After doing the first 10, loaded up a mag and shot them at 50 yards ... no accuracy change all falling inside 1/2" easily.  Thats GREAT !!
So spent some time making up @ 50 and going to find some live game to hit then with and see how the kinetic energy transfer is while seeing if i can mitigate pass threw shots.

In testing the speed, checked the weight ....  Stock H&N Sniper magnum .177 cal @ 14.9 grains & shot at 1050 fps.  Hollow pointed weight at 13.8 grains and shot 1070 fps.

Anywho .. what we got 

Scott S

Scott, I didn't read carefully at first and thought those were .22's. When I realized they were in fact .177s then that sure is some impressively fine detail work! Let us know when you perfect the mass production aspect and they become available for sale...

[Motorhead]

Staying with making hollow points .. or better ones anyways
Did some experiments on how well the STOCK NSA 12.5 did for expansion being shot into water in the low 900 fps range.

Then made a small nylon fixture a slug hand presses into where i could squarely drill the hollow point larger.  Went incrementally larger until at a drill size of .073" it drills the HP to @.075" being the leads so soft.  Tested in water ... POP it opens right up where the factory spec slug did nothing.


Shot my first ground squirrel yesterday with a "redrilled tip"  12.5 NSA at @ 42 yards, shot at @ 910fps.    Hit him on the diagonal behind the front shoulder where exit should have been approximately opposing side mid gut .... NO EXIT !!

This was telling the slug opened up.  Similar shots with 10.3 or 13.4 JSB are always pass threws like an ice pick.  Not with these modified slugs they don't !


Scott S



BTW ..... Do Not ask Nick at NSA to open up the HP hole size .. already inquired being told the High speed machine and requirement of extraction limits this HP being any larger simply can't be done 

[Back_Roads]

 Hmm I may try that with the 15 gr. , been only shooting the 12.5 gr. so far, ragged hole at 50, with a pretty much factory Marauder, with UTG Bubble level scope, and could be better if I were not the loose nut behind the trigger today

[KnifeMaker]

Well done Scott! For my uses, a hp that does not open is useless other than a way to have a lighter projectile without changing length appreciably.
Its biggest advantage is increasing sales. LOL.


I am still experimenting as well. Finished the second cavity of the NOE mold yesterday morning. Accuracy is superior to the non HP version and expansion is very good indeed.  4@76 yards, .185"   
The group included a slug from each cavity, None weighed or sorted in any way other than all are sized to.2228".


Stoked!!!
(Will have pic up in a few minutes)
Mike

[KnifeMaker]

Yes, I chickened out and stopped at 4 shots. Just can't trust the wind around here. 


4@76 yds, .185"-----
