Ok. How about this?

.22LR Whisper? An inside-the-case 75 grain spire point lead bullet in the .22LR case.


:D

Aguila has their sixty grain bullet that has quite a drop to it already ..... ah ... what's another fifteen grains ? Add it in and see if it will stabilize .

Oh and don't forget to recut the chamber and a few other things ;)

At 75 gr., the standard rifling twist isn't going to stabilize it. You already see this with some rifles and the 60 gr bullets. Velocities using SAAMI pressures are also going to be pretty slow, with pressure curves that may well restrict this to manual operation rifles only, as well.

Where would you find bullets of that diameter short enough to fit into a .22 chamber at 75 gr.?

All very good points.

But I'm the idea guy (not too many good ideas though) and leave all the details to the smart college guys.

:D

Ahhhhh. Thinking that you might have better luck resurrecting a Whispering .22 Hornet, or a .22 WMR Whisper. Longer case, with higher pressures under SAAMI. Still have to change the twist, though.

Hmmmmm. The .22WMR JR Whisper in 75 grain. Perhaps the .22RC Whisper?

Yes. Yeeeeees. I can see that as being a real thing. I'll get on it.

Red Dot!
Dang, Van! :?: That's a fast powder for a rifle round. It sure leaves a lot of room in that case too.

Sustinemus
9.5gr gave the most consistent f.p.s.
We could of reduced the fps down to 800, but at the expense of accuracy.


Muzzle 1000
(YARDS) VELOCITY (FPS)

....25 ...........986
....50 ...........972
....75...........959
....100.........947

Susti , it might not seem like much when you look at the weight of the powder . It is though rather bulky or "fluffy" if you will . I used to use quite a lot of it in loads for the .308 Winchester .

A lot of people seem to think it's the ideal all around powder for reduce thirty caliber(ish) military rounds . I don't remember who it was , maybe Jim Carmicheal , that said 13 grains of Red Dot was "The Load" for that type of cartridge .

I use a goodly bit of 700-X in my .223 Remington "gallery" loads and it bulks up good too .

"Approach these loads with caution as you would any off the net loading data. These loads may seem low power to us but they are very close to many black power and muzzleloader that brought a lot of game in their time. They are also super economical as to powder used if you have a mold, lead and primers"




Low & Slow: reduced loads
1. .308 Winchester
a. 26 inch barrel with a 220 grain NEI .308 cast bullet over 3 grains of Clays is almost silent
b. 24 inch barrel with a 150 grain RCBS bullet, 3 and ½ grains was needed and it was like a loud cap gun.
c. 150gr cast bullet* load 13 grs. of Red Dot in .308 or .30-06 at about 1600 fps
d. 170gr, cast bullet* 13 grs. of Red Dot in .308 or .30-06, about 1500 fps
e. 200gr. cast bullet* 13 grs. of Red Dot in .308 or .30-06, about 1450 fps
f. play with powder levels of Bullseye or Clays for silent loads...but you are not going to get there with 180 grain cast slugs and under.
g. 170 thru 190 grain cast slugs
i. 5 grains of WW231 or HP38 will go around 1000 fps
ii. 8 grains of Unique goes 1250 fps.
iii. 20 grains of 2400 or 18 grains of SR 4759 goes 1800 fps .
iv. * Note: Jacketed bullet velocities are about 120-150fps less than a lubricated lead bullet of the same weight
2. 3006 Springfield
a. 150gr cast bullet* load 13 grs. of Red Dot in .308 or .30-06 at about 1600 fps
b. 170gr, cast bullet* 13 grs. of Red Dot in .308 or .30-06, about 1500 fps
c. 200gr. cast bullet* 13 grs. of Red Dot in .308 or .30-06, about 1450 fps
d. 210 grains cast bullet
i. with 10 grains of Red Dot or Green Dot 12 grains will go 1200 fps (without recoil & very quiet @ about 700 ft-lbs of muzzle energy) good to 100 to 125 yards for training or small game hunting.
ii. 13 grains of Unique will go 1500
iii. 28 grains of 4759 will give 2000 fps with over 1800 ft-lbs of muzzle energy
