Sighting in a rifle with different cartridges

Postby Dkydog » Sat Jan 12, 2008 6:02 pm

If you sight in a 30-06 with a 180 gr. cartridge will it be sighted in for a 140 grain cartridge?
Realize this may be elementary question but I just need to know....
thanks in advance, :huh: :help:

It will be fairly close, but will require some fine-tuning.

Bullet weight, type, BC and the powders used and the rifle twist
all play a factor in the bullets drop once it leaves the muzzle.

On my 06, I never know where the new bullet will puch a hole,
one reason to sight in !!

100 yards can have as much as a 3" impact area, or more.

It is always nice to KNOW where a certain type of load hits.

Put it on paper. :thumbsup:

also, many guns react differently to different bullet weights. my fathers 243 will print 55's in the black but 87's are 4" right, then 95's are 6" further, then the 105's are a full 16 inches right and low. its odd, but alot of guns shoot different bullets to different spots. just shoot a few to find out how finnicky your gun is

Most 140s will have a higher BC, and will not shoot even close to what 180s are shooting. You can shoot different bullet types in 180gr and still not have them group in the same place.
