357 Mag Accuracy Problem

I reloaded up about 24 rounds of 357 to shoot out of my older style vaquero. the load:

Rem 357 brass
158 Lead FP
5.7 grain Unique
Federal Primer
at COAL 1.575

The crimp was set with the setting up of my Lee seating die.

I wanted it to be a cowboy action load. I shot at 15 yards and couldn't put 6 shots in a 5.5 inch shoot and see target. With factory Winchester 110grain ammo put all six in the target. Am I a bad shot or re work a loaded?

I shot 6grns of unique under 158grn lasercast rnfp yesterday and they shot quite well.I to am trying to find a mid range load that shoots as good as myfull power 2400 loads.If these bullets are soft you could be crimping them to much and scraping material off the bullet apon firing.lasercast bullets are quite hard. trailboss is also a good cowboy load powder.I could not get the accuracy i wanted using 38spl brass.found 357light loads better with diferent powders i have tried .Hope that helps.gspman

Heavier mag bullets usually like slower burning powder like AA 2400, but you do not want to use that for cowboy action shooting (you will take the target right off the stand, and they will be ****** at you).

At that distance, I would go back to the 110 grain bullets with a starting charge of Win 231 or trailboss powder. I like the Win 231 since it is easier to set FPS based on the amount of powder used.

Just my 2 cents
Jim

Actually I'd load up some 38 spls for that.

Seat and crimp using separate dies; crimp with the superior Redding Profile Crimp die.

Back off the Unique to a start charge weight and see if you can hit anything.

Thanks for the help.

sorry no more information I got the bullets about 1000 of them from my old man neighbor who doesn't own a pistol anymore. They are in a box marked 158grain LWFP and he wrote 357/38 special. I got the unique from him un-opened with a newer looking gander mountain price tag with a newer powder price on it.

I didn't mean I was shooting cowboy action I guess that was a poor choice of words I just want to go to the range and shoot here a bang and see I hit the target.

I will have to get a separate crimp die hopefully that helps.

Didnt see or get much lead last night while cleaning, going to go today with a bigger target maybe I am just a bad shot.

If you have calipers, measure the bullet diameters for both the lead and the 110 grain jacketed (pull those with your bullet puller). If you find that the lead bullets are smaller diameter, you'll have found your problem.
