Need help with jacketed rounds

[Jal5]

I finally got a chance to try out some 9mm I handloaded during the snow storms! Got a winner with Bullseye and Speer FMJ using CCI sm. primers.  I only have a few of the Speer projectiles left but I have a lot of Berry's plated in the same weight 115gr. can I exchange these or do I need to back off the powder and work up again?

I hope I get as good a result with Berrys in any case because those rounds were excellent for me!

Thanks

I'd use the same data. If accuracy falls off with the Berrys, I'd try reducing the load a little and see if the groups tighten up. If you're loading plinking ammo there's no advantage to running them hot. I've run the Berrys over 3.8grs of BE with good success on targets. This load is well below max in any reference source I've found. As always, use good judgment, and verify all load information through a reliable source before using it.

I recently fired Remington MC, Plated bullets, and Lead of the same weight using the same charge of PB.  From an accuracy standpoint they scored Remington, Lead, and last Plated.  The Plated was okay and price will be the determining factor.  The last purchase cycle I bought the Remington because they were only two bucks more than the plated. 

Published velocity for the near maximum load was over a 1000 fps.

Plated bullets occupy a position between cast bullets and jacketed bullets. They are soft lead, but have a hard outer shell on them. When loading plated bullets we have found best results using low- to mid-range jacketed data in the load manual. You must use data for a bullet that has the same weight and profile as the one you are loading. Do not exceed mid-range loads. Do not use magnum loads.

I have found that too heavy loads of plated bullets can cause the plating to flake off and accuracy goes to pot.

Dand:  Good information!
