The bolt on the Model 710/770 is not like a conventional bolt action rifle. For the last 100 plus years, bolt action rifles have all basically been made the same way; the locking lugs on the bolt lock up into the receiver, while the barrel is screwed on. The Model 710/770 is a completely new way of thinking. The bolt locks directly into the barrel, and the barrel is hydraulically pressed into the receiver. Also, there are three locking lugs instead of two. This gives the rifle exceptional strength and accuracy.
Since the bolt locks into the barrel, the receiver now simply guides the bolt. The receiver of the Model 710/770 has a self lubricating synthetic insert to guide the bolt into the barrel. With this insert, and the three locking lugs, there is a completely different feel. When pushing the bolt forward, there is a different feeling than on the Model 700 or Model Seven. This is because of the contact of the metal bolt and the synthetic insert and is normal. The "feel" is different, but the quality and performance of Remington is still there.
