155 or 160 gn. .45 cal bullets.

I have given thought to changing my .45 target ammo to the 155 or 160 gn. bullet. To do this I would need to buy a mold. This is simply due to the fact that it takes 25% less lead to cast bullets plus lead is getting harder to come by.  I have noticed 2 or 3 bullet profiles/weights for the lighter bullets. Is there a mold number associated with the preferred lighter bullet? Should the bullet have a long skinny nose to mirror the feeding of a 200 gn. SWC? I have noticed both long and short noses. TIA

I have some of the Dardas 160s, but not a lot of success with any loads past 25yds.
Any top secret recipes?

 I have found them to be very accurate at 50yd.  4.0-4.3 of WST is what I have used in my guns. 
4.1 is a little more accurate but not by much.  Seated to 1.62-1.64 OAL. Measuring from the shoulder is .928-.930.  
I tightened my crimp just a little, .466,  to build more pressure for reliable function at the 25 yd line and no ill effect on accuracy. 
 
I really like them.  No leading what so ever in the barrel.  Used to use the Zero 185 LSWCHP and loved those too but always had a ring of lead. Never seemed to affect accuracy but was still there when came time to clean.

You do have to make sure your not deforming or shaving the bullet as you seat it

Christmas came early. Thank you Gentlemen. I have been looking at that box of bullets for a while. Knew they had much more potential than the time I gave them.
Have a Very Merry Christmas.
