In your short barrel they may actually be slow on the bottom end of the load range. It's longer than the ELD and weighs more, so those loads will be safe, but possibly fast in a 16" barrel. In your case, depending on powder used, I would substitute data for a 230 Berger, I know both Accurate and Hodgdon have data for it. The reason for doing this would be knowledge gained, giving you a better idea of how this all works. You can use the data and load as a single shot, working the cartridge length down, watching for pressure signs. Une cartouche Hornady® Subsonic n’émet pas le.

Une vitesse de 311 m/s à l’impact entraîne une pénétration de 41 à 46 cm dans un bloc de gélatine balistique et 90 ou plus de rétention du poids de la balle. If the COL, like in your case, is longer than magazine length by doing that, the load will be safe to shoot, as long as it does not seat into the lands of the barrel. Les performances du 300 Blackout Subsonic atteignent ou dépassent les exigences du Protocole de balistique terminale du FBI. I have a little twist in Rebel's method that allows a pretty quick conversion of bullets in data.Ĭase length + bullet length - COL= seated depthĬase length + bullet length - seated depth = COLĬonfirm that the bullet is not seating in the lands of your barrel. Accurate's load data divides it into sub and super sections, so you can actually see what a max pressure load is. If it is related to pressuure, start in the middle. Keep in mind that most data for 200 grain plus data is for subsonic velocity, not max pressure, pay attention to that, it gives a little wiggle room for loads if max is related to velocity. You're on the right track comparing lengths, weight and seated depth. Easiest is to join a forum and say "give me load data for this combo". Start high and work your way down to subsonic. Since you will be developing subs, the deeper the bullet the more pressure i.e. Not sure what powder you have, but if using 1680, you can check recommended sub charges and quickly ensure you are not compressing.
I would make a dummy case to 2.25, measure base to ogive of another eld bullet, then measure cartridge base to ogive and subtract the case length to determine how much bullet you have in your case. How should I go about starting to develop this load? I will be shooting out of a 10.3" AR with a pistol gas tube. Most of those offerings are supersonic, but Hornady does offer a subsonic 208-grain A-Max load for the. 450 Bushmaster load fires a 250-grain FTX bullet. The 7.62x39mm load uses a 123-grain SST bullet, and the.
A 220gr SMK is recommended at 2.260" COAL. 308 Winchester are also both available with A-Max bullets.

The 9th ed Hornady manual has load data for a 225gr bullet, but upon researching it, the bullet is 1.558" long. Got o looking afterwards, and there is zero load data available for the 300 BLK with this bullet. I picked up some 30 cal 220gr ELD-X pills at cabelas.
