I go up in .5 gr. increments.

.5 grain is where I draw the line also.

For handgun loads I vary my charges by .3gr. Get to shoot more that way while finding the perfect load :wink:

When I was working-up a load for my Ruger SBH in .44 Magnum with 240's, I loaded H-110 from 19.3 to 25.8:

GRAINS GRAINS
19.3   22.7		
19.6	23.1		
20.0	23.4		
20.3	23.7		
20.7	24.1		
21.0	24.4		
21.4	24.8		
21.7	25.1		
22.0	25.5		
22.4	25.8

ricciardelli...You go about 2 grains higher than either of my books list. What load works for you?SGB

 

[ricciardelli]

Bullet: Sierra 240 Grain Jacketed Hollow Cavity
Powder: 25.8 grains of Hodgdon H-110
Primer: CCI-350
Case: Remington
Firearm: Ruger Super Blackhawk 7-1/2" barrel
Optics: Ruger open sights
Velocity: 1607 FPS @ 15' from muzzle

Firearm: Original Ruger .44 Carbine
Velocity: 1919 FPs @ 15' from muzzle

These are "warm" loads and I DO NOT suggest that uyou jump right in on them!

I also work in .2 or .3 gr increments for pistol work-ups. .2gr for faster powders and .3gr for slower powders.

Once I find a load I like, I load that plus & minus 1 tenth to see if there is any improvement. Then it's done. Now if it was a rifle load - THEN I would play with OAL some at that point to see if I could improve it anymore.
