I got 200 of matts 300 grain hollow points 44 mag ,before he discontinued them. They need to be loaded between 900 and 1000 fps is what his info was on them because they are pretty soft. I used info out of Lyman cast manual and started off with the min load for h110 for a 300 grain cast . Way to much on first 3 rounds I got 1150ish out of a 5 in barrel magnum reaserch bfr and all rounds were tumbling .
My question is what would be a good manual. Or place for reloading info for these . Need to identify some different powder and starting load for this combo. Also why would the bullets be tumbling at 25 yards . Looked like a buckshot pattern.

Sir, if you are shooting a BFR and the bullets are hitting the target sideways, then you need more than a different reloading manual. Something is wrong.
Lots of guys here will help, including me, so consider calling me tomorrow. I have a list of questions.

I'd be looking to smaller charges of fast burning powders.
If those bullets are that soft, they probably aren't holding the rifling.
I definitely would get away from any of the Magnum Powders.
Unique, Universal and others are great choices. Lyman Manual probably has a great selection of data...

Agree with Encore, unique, Titegroup, Universal, etc. I’ve used the bullets myself and pushed them at about the same 1150fps with no issues. I did get some leading quickly and that’s what made me stop using them.

I haven't had the gun long . Going to clean it up and shoot some factory ammo threw it first of next week to make sure nothing is actually wrong with the gun. Have to work all weekend. Thats first ammo I have shot threw it actually. I have several bfr haven't had any issues with any of the others so not really thinking anything wrong with gun . Hope not anyway. I was just thinking lead was to soft for higher velocity. Not made for mag charges is what Matt told me higher end 44 special loads.

Did you actually get key-holeing? Sideways holes in the target?

This thread highlights one of the things I've missed.
I've never measured the rifling land heights in a BFR. I've measure lots of barrels on revolvers (and other guns) and found lands ranging from .004-.007" high.
All have shot well with the right combination of bullet size, hardness and velocity. Clearly, the taller lands would grab the bullets better.
I would suspect the shallow lands would not play as well with undersized or soft bullets or those that were pushed too fast.

There is either something off in the gun specs or you have an ill sized bullet that doesn't fit well. I would start by checking cylinder throats, barrel thread choke, and slug barrel to see what size it is. If the gun specs are on the money, it is an ill fitting bullet. Soft lead is not the problem. You would be amazed how soft a bullet you can shoot if everything is sized to fit with each other.

I dunno...when a manufacturer posts the velocity warning then discontinued the bullet, it sets my alarms off.
We've gone from an occurrence to a documented pattern of problems.

Pull the cylinder, look in your barrel, and tell us what you see…

Presuming this is a brand new BFR .44 Mag, my first target is with a KNOWN LOAD----whether factory oil handload. Accuracy, in order of importance1) Revolver. 2) Bullet. 3) Load. David Bradshaw

Looked at the cardboard last night all the bullets are hitting nose first. But are turning onece they hit. They may be trying to open up already as shoft as they are. Wont het to do anything with it till maybe this weekend if a goes well. Going to try slug barrel And see,never done it but should be learning experience. Lol. Also whats best way I can measure chanbers. Never done that either. Can it be done with calipers.

To measure the throats, you cane take a soft bullet, tap it with a hammer slightly to bump it up just a little bit, then drop in the chamber and drive it through with a hard wood dowel. Then measure. A micrometer will give you a more accurate reading, but a caliper might get you close.

Be absolutely sure to lubricate the barrel and a little on the bullet to help it go. I got a bullet stuck once, then broke off the wooden dowel that was driving it flat with the end of the barrel. "Sucks" does not even cover it. I bought some bronze or brass stock that was under bore diameter and use that now for pounding slugs through.

Haven't had a chance to measure yet but took the gun apart and cleaned it up really good . It actually had shards of lead in chambers and some lead build up from the 10 or 15 rounds I fired . (I did pick up the bullets they are so shoft that I can scratch lead off with my finger nail.they are sized at .430 they won't fall threw on ther on in chambers but with a little bit of pressure on rod I can start to push threw.) But any way I cleaned it up and took and shot some factory white box winchester 240 grain soft point threw it . Probly 20 rounds at 25 yards shot in a nice little group no bullets holes looked funny . Even shot 5 or 6 out to 75 80 yards at a 8 in gong. 4 out of 5 hits very happy with that for me.
