[QUOTE="Skimbleshanks, post: 1789550, member: 22552"] The weatherby cartridges and chambers were designed with the oal and freebore lengths for a reason. You are discovering that. Back off to starting loads at or below book max coal and I imagine your blown primers and pressure will go away. You dont have to be near the lands for it to shoot well. Some like being close to the lands some like a bit of a jump and some NEED a bit of a jump. 7RUM had like .400" freebore if memory serves. The rifle will tell you. Being new to reloading isn't the time to push things to the max. 300 weatherby loaded to the book isn't something to turn your nose up at. Try and be happy with what it is and don't blow your face up trying to gain 50fps. If you absolutely HAVE to have more velocity then you might want to look for a 300 RUM, or some wildcat based on the Lapua case. [/QUOTE]
