Any good load data books for boolites?

[tayous1]

Trying to reload for my 300 BLK and I'm having a hard time finding load data for lead boolites . Does anyone have any advice?

Nothing about cast in print. hornady #9 has whisper/blackout data as do all the manufacturer's websites. Also there is dedicated forum 300blacktalk.

Have the Hornady but the OAL when reloading is always way to long that they talk about in the book. Or I'm missing something? So it's touch and go with the 300 BLK? Any advice on how to convert jacketed ammo to lead when looking at load data?

Use the Google search function here, and plenty of info will show up. Also there is a bunch of data at 300blktalk.

I have had to modify 300 whisper data for cast loads in the b.o. in the past.

these are for jacketed stuff and wasn't a lot of help for me when I was looking for slower loads.
I dug around some and had to make up some of my own data based on some older whisper stuff I found.
my first load was 9.0 grs of AA-#9 with a 165 gr boolit giving me 1300 fps from my bolt gun.
the second load I come up with is 3.5-4.0 grs of 700-x and a sr primer with the LEE 230 gr boolit.
hornady has some decent data you can make useful, and accurate has some better data on another website that could be helpful.

Funny part has been the COL that Hornady gives it's way to long they say for a 150 gr FMJ 2.235 so I did it and the round would not load so I bought some factory rounds and found there COL was 2.052 now my rounds will chamber. It would be sweet to do load data for a living!

I'm sure you thought of it but use caution, that smaller oal will reduce case capacity and make pressures higher.

I have but the oal of what I'm told in print so far is way to long to be used in a AR-15 type rifle.

Because of the many different designs, ogives, radiouses on projectiles, you have with each one different OAL's that have to be determined by the magazine fit and throat. Most rifles your only bound by the throat but with the AR platform your also bound by the mag.
If your loading for the 150's, 2 tenths is not going to be as detrimental to capacity and pressure like a 240gr would be.
If it were me and I had good data in your instance I would decrease the start load by 10%-15% and work back up watching for pressure, until your ar cycles.
I have a 300bo pistol, and at the height of the powder drought found myself in the same situation. But I had it twice as bad because I didn't want to burn up my typical powders plinkin. I had in fact picked up Alliant 300mp which has almost no data for anything. I had to take and compare powders of same burn rate and make my own data. I started real low and worked up until I had a full cycle. I never could get the lee 230's to cyclewith out extreme pressure signs, but the lee 155's were much easier. By the way alliant 300mp is a excellent powder.
You can load one case at a time, with each load, until you get the magazine to catch the bolt. Then load multipules and check for feed. After the mag catch works reliably you shouldn't need to increase charge anymore. Watch for pressure, be safe.
