Diffrence Between 165g and 180g ammo ?

[Dozer]

Can someone chime in on this . I understand the projectile is heavier and the effects on the target. How about perceived recoil , accuracy , wear on firearm?

none none and none

Dozer:

You might feel a little difference in the recoil (IMHO). Otherwise, I wouldn't worry....

HOWEVER....

Some loaders will put lighter powder loads behind lighter bullets for "target loads". THAT will decrease recoil and wear a little. My favorite .45 is a 200gr lead SWC instead of the usual 230gr, and it's loaded about 20% lighter. Not a lot of change in the point of impact for me, and the full-bore loads aren't particularly punishing/surprising, but it's a little easier on my daily carry gun's very limited service recoil spring.

(The gun weighs about exactly the same as my other two 1911's. They don't mind anything I put in 'em.)

some people say different weights affect accuracy i have not noticed this shoot them both and see which one you like more

Care to expand on this? What are you carrying? what caliber? etc...?

My usual daily carry is a Kimber "Compact Custom". That's a 4" all-steel 1911 clone (.45ACP) on an "Officer's" frame.



I've added night sights and switched to a Para magazine with a finger rest instead of the bumper pads. The grips and arched MSH are also "mine".

Kimber recommends replacing the recoil spring at about 800 rounds. Wolff makes a somewhat better spring that'll take a bit more abuse. The 200gr SWC's seem to help there too.

rogerxd45: What you're referring to is probably more "point of impact" than accuracy. Projectile weight and shape, as well as the amount and type of propellant, all tie into this. I have one supplier who loads the 200's so light that they almost feel like squibs when compared to the 230's. I had the opportunity to fire a few in a Springfield Micro Compact. Smooooth.... The other suppliers loads are a lot heavier. Non-issue in my Kimber, but they felt a lot snappier in the Micro. The Kimber is small, but not tiny, and weighs about as much as my other two rather more full-sized 1911's. (Come to think of it, one is a full sized GM clone.)

If you take the bullet weight and multiply it by the velocity and then divide that by 1000, then it will give you a "power factor". Now... A 165 grain bullet and a 180 grain bullet reaching the same power factor, the 165 graain load will have a snappier recoil. That being said, you can use a faster podwer and a lower charge to reach that power factor with the 180 grain bullet and reduce the amount of gases that are generated during the firing of that bullet. This reduction in gas reduces the amount of recoil thats generated.

Bullet weights have nothing to do with a gun wearing out faster or slower. Its the power of the load that generates recoil and batters the gun. Faster bullets will accelerate wear in the barrel but at pistol velocities, you will never notice a difference.
