I begin today’s report with a large correction of Part 1. I said the Smooth Twist X barrel is not rifled until the end of the barrel. That is true of the original Smooth Twist barrel, but not the Smooth Twist X. The Smooth Twist X is rifled all the way up the bore. I have read many reports of stunning accuracy from this rifle — actually from the entire Dreamline series — and I hope the test rifle will be one of those.
Start velocity test
Today I will look at the velocity of the test rifle. Now we know that there are three adjustments on this rifle. The regulator is adjustable, the air transfer port is adjustable and the hammer spring tension is adjustable. While the manual sadly lacks pertinent information on how to adjust any of these things, reader Yogi posted a link to the FX drawing of the Dreamlite that shows the hammer spring adjuster is a rack and pinion gear.
