Bmt85, Hoot, and everyone else... Thanks for the reply. Sorry it took a minute to respond. Unfortunately, I have to work to pay for this little hobby.
I took my calipers and did some quick calculations of 50 spent casings I have. The average length was 1.683 with a mean of 1.683. The shortest was 1.677 and the longest was 1.687. Being new to basically all of this, let me know what you think. I have bought everything to start reloading, but I am still in the process of learning as much as I can before I begin. Based on the feedback from this post and my limited knowledge of twist rate and this gun, I am thinking that I could use a smaller bullet with the minimal powder and start working my way up to see if it helps with my issues. I am a little confused since I have read some other posts about using the Hornady 225g FTX, but Hornady doesn't list it anymore for the 450 BM. I will be the first to admit I am new to this, but I am pretty OCD. I have a lot of experience with QA, and I believe reloading is definitely doable, but I hope everyone is understanding when I say that I am going to need some feedback in the early stages as I am fully aware of what stupid mistakes/assumptions can lead to...
Mike
