    158 grain bullet

    Is it safe to use data from my reloading books on a 158 grain bullet design that weighs 160-162 grains?

    If you don't go full max it will be ok. But keep a close eye on what you are doing.

    Did I ever mention that I hate to trim brass?

    I think of load data as guides rather than recipes since we rarely use identical components in identical firearms under identical conditions that were present in the lab. Probably why different manuals have different results and recommended maxes.

    All that being said, the 158 gr data should be a reasonable starting place for load workups.

    Just like the Manuals say; use the starting load and work your way up.
    Happiness is a Warm GUN & more ammo to shoot in it.

    My Experience and My Opinion, are just that, Mine.

    The short answer is yes if you follow the above advice.

    Can you give a little more information? Which cartridge, which gun, which bullet?

    Pay attention to bullet bearing surface and seating depth. If they are comparable or the same as book data you mention, you'll be fine. If not, adjust load data accordingly.

    My experience comes from using 158 grain data for 165 grain lead SWC powder coated boolits in a 357. The starting loads were fine. When using powders that produce higher velocities, the brass was hard to extract at the top end. With those powders, I backed off until there were no extraction issues for my max loads.

    +1 on what was said.
    You need to try different powders to find
    the one that works best in your gun.
    The guys and gals here can steer you in the
    right direction as far as powder.
    If you give us more info on the gun, cal,and what you are
    doing with it.

    I am shooting a 158 grain rf lee boolit,it is coming out of the mold at 160-164 grains.I am shooting it out of a 357 smith.I think pj and a few of the others have put my mind at ease that it will be safe to shoot if I start with the starting loads with 158 grain data.I am currently using a 105 grain lee section that is coming out of the mold between 105-111 and the 105 grain data is working fine on medium loads.

    My 158 boolits tend to weigh 165 just start low and take care .

    Yep, as noted above by the members, just start with starting loads. Your alloy prolly has more lead in it than the "158" weight designation with Lee's alloy (I have a nice Lee mold for 45 Colt with the advertised weight of 255 gr, but my bullets are running 264 gr. average, with my 20-1 alloy...

    One last question....my Lyman book says c.o.a.l. For 158 grain is 1.575 and that’s what I am making it but I noticed the 160 grain right next to it is 1.590,so am I right to go at 1.575 for the overall length?

    The boolit with the 1.590 COAL is a round nose with a different nose shape than the SWC you are loading. Each boolit will have it's own COAL based on which crimp groove you are using if the boolit has more than one, and the shape of the nose.
    Your boolit has a crimp groove, yes? Just crimp the boolit in the crimp groove and go with it. You are going to work up from lower charges anyway so there will be no problems show up until you get to near max loads if any problems show up at all.

    I do it....my favorite 38 cal mould is a NOE 360-160-WC (Lyman 358432 160 gr. recreation).
    you have to start somewhere. There's not a whole lot of published data for 160 grain boolit's ....Trust me !
    Two grains in boolit weight isn't that much of a stretch , I can get that much with just a change in alloy .
