I have Nosler 5th edition, Sierra edition V, Speer 14th edition, Lyman 48th as well as Hornady 6th and 7th editions. I also have a Hornady 3rd edition, but it is so old, the 35 grain bullet was not invented yet, even the 40 - 50 grain V-max was not out yet. None of them list a load lighter than 40 grains. I am not sure why. Hornady and Speer makes bullets lighter than 40 grains, but neither list any thing lower than 40. I am not sure if the bullets will not hold together, you get undue throat wear, or maybe the bullet is so light, that the powders suitable to get high velocity will not fill the case enough that it causes dangerous pressures, just not sure. I also have some of the 34 grain Mid South bullets, I have used them in my 22 Hornets and 221 Fire Balls, I have not tried them in one of my 223's yet and do not know if I will. They are not the best for BC so long range shooting will be better if you use a 40 V Max or 40 Nosler ballistic tip. If you have access to a Chronograph you could workup a load yourself. Start with 40 grain data and work your way up little by little. If you can get to 3900 - 4000 fps out of a 24" or 26" barrel, I would call it good and stop. Just remember you are flying by the seat of your pants. I have no idea how the powders suitable for the 40 grain bullets will react with a bullet 15% lighter. You may get excessive pressure long before you get to 3900 fps and will not know it. There are some software programs out there where you can calculate loads, but they are just ball park at best. Please be careful. Good Luck and Good Shooting
