I have run into a pressure problem (bolt sticking) working up a load for my .338 Win Mag.
Data: 225 gr Barnes Tipped TXS bullets
IMR 4350, one grain increments ranging from 63.0 gr to 67.0 gr.
Mod 70 Win with a 21" stainless barrel
Rest: Lead sled... to reduce the effects of the weakest link... me!
Problem: The rifle loves the 65.0 grains powder, 0.6" groups at 100yds. but the bolt sticks occasionally but not always. The manual gives a load range for IMR 4350 of Min 61.0 gr to Max of 67.5 gr.
I am looking for any suggestions, I know dropping the powder charge will eventually do, but the groups open up to 1.25" at 100yds with 63.0 grains... kind of defeats the purpose of handloading....
