9MM load development 4 gun challenge FAIL a work in process

Today I am working on a new 9 MM load. I am going to do plenty of testing because a I have a large quantity of these Seirra 115 grain JHP bullets that I am going to load. Thanks for watching please subscribe. For agriculture related content please check out my other channel. 10 cow ranch

Thanks for watching

I have shortened 9mm to better enable them to "turn the corner" to enter the chamber. I always use a Lee Factory Crimp die in a seperate step. Mine is a Beretta 92B. Love it.

This bullet does require a little shorter OAL Thanks for watching

[@vaughnpotter1462]

I found the same thing in regards to oal. Had to seat them to a 1.03 oal length in order to function in all my guns . I cut the powder charge accordingly

[@chrisevansgunshorsesranchi699]

After filming the video I made some changes to the load . 1.03 OAL same as you I cut the powder charge to 4.5 gr of TG. I will do a follow up video in a few days. I am surprised at the velocity. I think I am about 100 fps faster than expected. I have you seen the other channel?

[@vaughnpotter1462]

I have seen some of the other channel 👍🏻
Seating deeper increases pressure a lot. I remember a old article saying pressure can double depending on how much deeper the bullet is seated

[@chrisevansgunshorsesranchi699]

Thanks for supporting the other channel. Yes seating depth is definitely something we need to be thinking about. I am excited about these bullets. I hope I can get them dialed in. What is your best 9mm powder??@@vaughnpotter1462

Greetings. Have you heard of the so-called 'plunk' test? With the barrel out of the pistol, drop a loaded round into the chamber. It should fall freely into the chamber. On a cartridge like the 9mm that headspaces on the mouth, it will hit with a plunk, hence the name. With the cartridge fully in the chamber, the case head should be a bit inside the end of the barrel hood. If it doesn't plunk, or fall in freely, there is a problem, whether it be too long cartridge OAL for the bullet profile/chamber shape combination, or insufficient sizing, or maybe even crud in the chamber. You are right, in a cartridge like the 9mm, with such a small powder chamber, even small differences in seating depth can make a big difference in pressure, especially with certain powders. The 9mm already operates at a fairly high pressure, so it is easy to exceed max pressures without much warning. I have noticed a wide range of case volumes in different brands of 9mm brass, and even in different lots of the same brand. The 9mm can be a little tricky to reload and get consistent results, like other small cases.

Yes I did the plunk test with the Taurus. I will posting a follow up video maybe tomorrow I hope with more success. Thanks for the great comment
