How many grains are most using in their .58?

[Kevin Tinny]

Hello:
Agree w all of the above based on my two.

But, am using between 43 and 47 of SWISS 3F.
Must test one-half grain ABOVE and BELOW to fine tune grains.
A half-grain can make a visible difference.
Q-Tip coat insides of plastic tubes with any talc powder to reduce static cling.
Try to achieve light to moderate bullet pressure on powder.
Banging rod on bullet changes lots of things and can raise impact an inch or more at 50.

One thing, when benching: "benching" infers front AND rear bags.

Be sure the bench AND FRONT REST, IF ANY, have NO movement.
KEEP CHEEK AND BODY PRESSURES ON RIFLE LIGHT AND CONSISTENT.
Wind can deflect up to an inch or a bit more at 50, so shoot same flags.

Please report results.

Respectfully,
Kevin Tinny
