[QUOTE="tacomHQ, post: 2071352, member: 67159"] A daily fan of this site and always quite insightful. God knows I have no wish to argue the Wrapped Barrels.... Though I will challenge what a steel barrel is. The term 3D has been used (like a club) and we think in 3D. To those who do not know us - TACOMHQ- along with long range optics we produce a type of barrel. It is not in competition with Proof or any wrapped barrel. It is not a light weight barrel and certainly not a mountain gun. However, if a barrel 32 inches long that starts at a weight of 6.2 pounds, is pound for pound significantly stiffer, well over 300% more cooling surface interest you -look us up. WE do cool the chamber and barrel by both a huge surface area (>300%) and active air flow thru the barrel. Our 300NM does not show heat signs until well into the deep teens in a shooting string, cools very rapidly, shows consistently less group drift, less SD drift, less velocity drift than standard barrels... and longer life. You will see the only existing videos of complex computer simulations of a barrel whip and vibration. While we are typically known in ELR for our optics, teams are well into testing of our barrels along with 3rd party load development people and all - all - to date have noted that our barrels are an outstanding product. "The real deal" per Cal and Precision Rifle Blog (see video). Loading development- 3rd party person after person note our barrels are among the easiest if not the easiest/most forgiving barrels to load to due to their stiffness and ability to shoot large width ladders and bullet weights. The term .416 Bench gun has been used to describe the accuracy achieved- and he has shot CF extensively. You will also find our recoil event is different/less due to reduced vibration/whip.
