Guys, if you’re switching from say Winchester 55gr FMJ to Hornady 55gr FMJ,

would you work it like a new load, or will my workup on the Winchester be just fine for the Hornady?

This is strictly for plinking, not precision shooting.

Thanks

If my load was close to the max for that particular round then I would start over and work my way back up just to be safe.  If it was just some middle of the road "plinkin' round" then I would load a few of them up the same and see how they shoot.  If they shoot to your needs then start crankin' them boys out.

You will see much better accuracy with the Hornady 55 gr FMJBT over the Win.

If you gave your load with Win bullets, I could give an answer on switching bullets.

Just don't know how hot you load.

Drop back 10% from your existing load and work back up is the safest way.

Reduce the old load 5% to start.

Sometimes bullet ogive shape or jacket construction will cause pressures to increase with smaller charge weights.

I don't use that powder, but the Hornady's are worth the time to work up a new load.

I use a similar load and have not had any trouble switching between bullets.

You should be fine, as long as the case, primer and powder charge stay the same.

YMMV
