Got a question about load data and the lyman manual

[7hatGuy]

Ok so i finally got my lyman reloading book and have spent the last hour or so reading. I am looking at the load data at this point for 223. I purchased a 62gr sp-bt(soft point-boat tail) projectile to use. It was all that was available because of this mess happening currently.

anyway looking in the book it has load data for a 62gr FMJ. Where do i find the data for this particular bullet or can i use the data thats given in the book for the FMJ?

So just went and checked the link and it doesnt have an option for a 62 grain bullet

accurate lists a 62g bthp

ok so what do you do when you have a bullet and are using a powder that doesnt have load data for it? I have hodgdon h335 on hand.

According to Hodgdon with H335 it lists this.
BULLET WEIGHT62 GR. SFT SCIR
Manufacturer Hodgdon
Powder H335
Bullet Diameter .224"
C.O.L. 2.260"
Starting Load
Grains 19.3
Velocity (ft/s) 2,678
Pressure 47,500 PSI
Maximum Load
Grains 21.4
Velocity (ft/s) 2,887
Pressure 53,600 PSI

Start low work your way up test every load as you go up.

If one is to use unknown components then use closest pub data and chrono a few and examine case, extraction, etc. The happening in hand loading mysterious components and trying to shoot them out of homemade or substandard guns is the perfect storm for an accident.

I would start 10% below the suggested load and work my way up .2 grains for 10 rounds called a ladder test.Do you have a cronograph?velocity is how you get your load

Don't forget about case preparation. It is important too. Using the same bullet weight for a jacketed bullet, but different design, i.e. fmj, sp or hp, is what I do. Otherwise I dig around and find the data from another source. Most reloaders own more than one manual. Always check immediately for pressure signs when working up a load.

I am going to get Some of the other manuals out there I’m just not in a rush currently still need to buy a chronograph but thanks for the info!

I've been reloading for over 45 years. I have never owned a chronograph. It would be useful, though in trying to hit target velocities when working up loads or if I were concerned with getting the minimum power factor for certain pistol competitions. I always have been striving for accuracy and having "borrowed" loading data from knowledgeable reloaders, I've had good luck.
