.357 Max rifle ballistics?
« on: November 29, 2007, 01:25:10 PM »
I see quite a few folks here are into the .357 Maximum as an easy rechamber for .357 Mag. Handi Rifles and I am interested. However, the only load data I've come across, and that ain't much, is from handguns, I'm wondering what you get from a 22" barrel?

I was getting 1900fps from mine with a 180gr cast bullet.

Velocity  2100

So,
According to the chart you could sight your rifle high 2" high @ 100yds and be  on at 150 yds ? Could you also assume that 1/4" inch high@ 25 yds would also be zeroed @ 150 yds?

I'm just trying to make sense out of the table.

Ballistic software just gives you an idea, shoot it to find out what will actually happen. ;)

Thanks Tim,
I hope this helped Coyotejoe as much as it helped me. Because you have the scope mounted above the bore, you really have to understand what is going on with the bullet path and not just the drop of the bullet out of the muzzle to understand the "zero" of the projectile.

Thanks again,

Yes, scope height above the bore will affect the predicted results, that's why shooting it at your intended range will help the most, no surprises then. ;)
