Working up a new load

[Forester]

I was able to acquire some 124 grain hollow points and my plan is to build a load to be as close as possible to my defense loads which are 124 grain Gold dots
Both projectiles have a similar profile.
My plan is to reproduce the same OAL and velocity.
Powders available are
Tight group
Red dot
And W231

I would appreciate any suggestions or input on other variables to consider.
Thank you.

Are you planning on loading these for self defense or practice?

I plan to set them aside in the event that my supply of SD rounds get liquidated and I can't replace in a timely fashion.
So it's a backup plan for self defense

Have you reloaded a lot?

I loaded up a bunch of 124 gr V-crowns with a hot load of longshot, they shoot really well out of my vp9.

So with a bulet that is a close match, what you need is a powder load that gives you as close to the same speed as the factory load gives.
Do you have or can you borrow a Chronograph? If so Chrono a couple of factory loads for a base line, and go from there. DR

PS relying on factory data or book data will only get you so close. DR

This kind of task is one that I take my loader with me to the range. Prep up some brass, prime them, and take bullets and powders along.
Load three to get an average reading, shoot them and make adjustments from there!
If you get to the high end of a powders data and are not getting the velocity you need switch to a slower burning powder. Good Luck, DR

Have you reloaded a lot?

I've loaded about 30K over the last three years.
All 9mm
So more than some. But still have much to learn.

I have a chrono.I will find the average speed and use that as my target.

Thanks, I feel much better about any suggestions because 30,000 rnd means you know what you are doing.

Win 231 is my favorite powder for non magnum loads. When I see it as one of your choices I feel confident in recomending it.

What machine are you reloading with and do you case Guage your reloaded rounds?

Sounds like you are prepared for any variables in the powders you've chosen.

Post your results as I'd be interested. I have a bunch of tight group and red dot itching to be put to use too.

Using a Hornady LNL
I use my barrel to drop test each round.

Good equipment so it looks like you will be fine. My book says 4.5 is max load of 231.

Which firearm will you be useing.

M&P 2.0 compact
Shadow systems MR920
Both 4.0 barrel
4.5 is what currently use with a round nose polymer coated bullet
1.135 length

1050 FPS

In my opinion you are good to go. Let us know how it works out.

Ten 4.
It may be a while but I'll let you know where I end up.
thanks.

What brand are those 124 grain hollow points?
I doubt very much they'll match 124 grain Gold dots in performance no matter the velocity.
You should find the velocity where those particular bullets perform the best and then load them thusly.

RMR multi purpose round.
Good thought, I'll see if they have any suggested velocity
Thanks

9mm 124 Gr. RMR Jacketed Hollow Point (Multi Purpose Round) Bullets | RMR Bullets

We’ve been testing them for a while in calibrated ballistics gel and results have been very promising. It is recommended that you shoot them at 1150 FPS or more to get reliable expansion for self defense or hunting purposes. This bullet also makes a great target round. Check out this video of...
