I am begining to start working up a load for my Browning X-Bolt in 300WSM using the 190 Berger VLD. I am going to start at 61.6gr with IMR 4831 and end at 64.6gr. The longest my magazine will allow me to seat the bullet out is 2.900. This gives me .110 jump to the lands. My make up will vary the loads by .3gr for a total of 11 rounds. At 64.6gr the load is compressed 102.6%. Is there a problem compressing IMR 4831 2.6%?
Thanks Tom
