Loading 300 HAM'R compressed loads - 02/26/24 10:39 PM
I am new to the 300 HAM'R.....just used a Wilson Combat barrel to convert a Aero Precision 5.56 that I just did not shoot. I have been shooting and loading 300 AAC with no real issues. I have a question regarding some of the loads I am seeing being floated around. I am in the process of setting up my Dillon 550C and the first thing I notice is the case capacity. I am planning on using CFE BLK, have had good luck with it on some loads with AAC, particularly heavy subsonic.
When I look at the range of bullets recommended to the HAM'R, the lighter rounds like the 110 Hornady Max are running up to 29 gr of CFE BLK. I am using Starline brass and at about 26 grains, the case is filled up to the bottom of the neck. I don't have any experience with compressed rounds but it sure seems like that is going to be very compressed with 29 grains.
With heavier bullets, in the 125 range the loads get down around 26 gr.
My questions are this: With lighter bullets, would I be better off using another powder. Can you really get 29 gr into that case and not compress it too much. I have no idea how much is too much.
The 300 HAM'R has not really caught on in Montana (where I live) and none of my shooting/reloading friends have any experience with that round. I am the group guinea pig on HAM'R
Thanks for any advice on this..........
