Just an " FYI " for anyone interested in tinkering with " .22 Rimfire Bullet Modification ;  Hollow Point/ Flat Point / Cup Point /..." ?  

I'm currently living in an apt, .. space is a bit cramped, which restricts many of my " Tinkering Projects ".

OK, I admit it.  I'm stumped.  Why do you need to change the nose configuration of factory-loaded ammunition

Well, most folks try testing several different brands of .22 LR Ammo, in their " Rifles ", to see what groups best ... ?

Others ,  might like to use the same accurate ammo ( Rnd Nose ? ) for " Hunting ",  with a modification , possibly as a  " Hollow Point " ?

And then , there are some folks hoping on improving a " Marginal " ( Less Expensive ) Ammo , into something better, by " Tinkering " with it a bit !!

" ME ",  I just like tinkering with them.. It's a " Hobby ".. nothing more, nothing less

Please review the above link, which provides a pretty good description of " What & Why ".. better than I could...

p.s; I also have a " Paco Tool "

neat!

Thanks!  Every once in a while, I accidentally learn something new.  

When I shoot those bullets out of that yellow box of aguila in my 10/22 they already all make a 1/4" moa group at 50 yards. Is it really worth messing with them?

Well, this is the closest thing to " Reloading " for Rimfires  !!

IMHO: It has alot to do, ... with " Consistenly Resizing / Reforming "  the Bullet Diameters .. on less expensive Ammo.

Hey, it's not for everyone .... ?

I currently only play with " Bolt Action Rifles ".


It might not work well for semi-autos (Oversized Bullets ,  & chambering issues) ... ?

Believe me, I'm not one to question why hunters/loaders do much of anything as any reason is good enough. Kind of like adding a new gun to the arsenal. No good reason for it but what it hell...why not!

Do keep us informed on what you find out!

BTW what rifle/barrel/twist etc do you use and what prompted you to take on this project? What do you hope to achieve?

Hi.

Just for a clarification: There's really no sense in trying to improve " Expensive Match Ammo " or ammo that is extremely accurate in your partiicular Rifle.

However,... if you already have a particular "  Match Ammo " ( Accurate ammo ) you could Modiify it for " HUNTING " ; i.e : Hollow Point / Flat Point .. ?

I intially started off tinkering with a " Paco Tool ", after reading an article a few years back. It lacked the fine tuning: Adjustments/ Length.

I also have a " Neal Waltz Tool ", which I really liked.. But, I somehow misplaced the two forming Rods.. I feel like a

I'm hoping to re-locate them ..?

I decided to order the " D Rock Tools ", as a replacement, & it has more " Forming Rod Options "..

Here's another informational link, comparing the Three Best known, Modification Tools.

Neal Waltz, Paco Kelly , D Rock:

I now own all three  

My personal agenda  :  I was attempting to " Modify " ; Aguilas SSS 60  ( Shorten / Reform ) enough to reliably stabalize , using one of my standard 1-16 twist Barrels .

I also hope to achieve  some measurable improvement in accuracy (?)  , trying to stay under " Subsonic Velocity ".. ?

I'll trim the Bullets ( Aguilas SSS 60 Grn :  -5  / -10 grns ) with the " SGB TOOL " ( File & Shorten )  , and then attempt to  reform ( Swage ; Diam / Reform Tip ) the Bullet using the " D Rock Tool ".


TEST RIFLES  : Rem 40X / Win 52D / Rem 540 XR / Rem 513T / Savage NRA 19 / H & R M12 /  Martini 12-15 / Kimber 82G / Savage MK1 FVT.

I've been playing with this project, on and off, for over a year , as a casual Hobby
