New Load

[tward1604]

What do you do when you want to work up a load and no data exists for your cartridge/bullet combination?

[Scoobyh]

What cartridge/bullet data are you looking for? Someone might be able to help.

I'm a shotgunner and I deal with this constantly. There's rules you can use on that side of the coin. As far as metallic, it gets a little sketchy when going off of no load data.

What are we talking about here cartridge wise?

Starting point might be another cartridge of similar case capacity and bullet weight.

Pick a different combination. There's likely a good reason there's no load data for the combination. That said, what combination are you looking at? Perhaps one of us can help. I have almost every current load manual published.

Post up what cartridge and projectile. Most likely need to know your barrel twist as well.

In my experience, when there's no load data for a desired bullet/powder combination the problem usually is that the desired powder is either too slow or too fast for the cartridge and/or bullet weight.

Quickload is your friend. You may have to build a custom case profile but it will give you the data if case dimensions are known.

This is assuming you are talking about a wildcat cartridge.

If not PM me and I'll see what I can do with Quickload.

This was common in the early days of working up the Grendel.

Powder burn charts and use the limited data.....then start low and use a chronograph to find pressure spikes before the brass shows anything.

Then stop when you see a spike.

What case, powder and bullet. The GS may have answers to the questions you seek.

its actually for the 30-30. The only data for the company is for a bullet 15 grains lighter. There isn't a similar bullet that is near the weight and length for it. The bullet weighs 165 grains but is longer than every other 30-30 bullet out there. Actualy the 150 grain Nosler E-tip is the only bullet longer.

I'm looking to load the 165 grain Peregrine bushmaster over varget in the 30-30. I have a marlin 336. All the specs work out just fine there just isn't any data for it. like i said they have it for their 150 grain just not the 165.

Before anyone says anything about cup and core bullets being sufficient for the 30-30 i know they are but what good would it be to be a reloader if i'd be content with whats on the shelfs.

170gr bullets with variety start at 22.9gr then go up to 33gr. Data per Hodgdon.

I would run with that data if I was in your shoes.

Run a test ladder then run for accuracy.

I was kinda thinking 10% of a 170 gr load. I'll try 22.9. How much will a ladder test really help on a 30-30 lever gun? My only gripe with the ladder test is you go through a lot of bullets and they aren't cheap. Especially having to order them from south africa

[Outbreaker]

I would shoot 1 bullet 1 gr apart from 23-33.

Modern lever or old lever? If older do 23-30.

Safety over cost.......or it could cost you a lot more.

My dads 7mm mag stuck cases at minimum powder charges with some bullets.
