[QUOTE="Fiftydriver, post: 459015, member: 10"] I tested 20N29 extensively in my 338 Allen Magnum and with 300 gr pills, I fully agree with Joel, no real improvement over H-50BMG. That said, when I moved up and tested the custom 350 gr ULD RBBT from the old Wildcat Bullets Company, it worked EXTREMELY well producing 3200 fps easily out of a 33" barrel length and groups at 200 and 500 yards often in the 1/4 to 1/5 moa range for three shots. In good conditions, 1/2 moa at 1000 yards was not uncommon. So for 300 gr bullets, I agree, no real advantage with it over H-50BMG, for extremely heavy bullets it shows more advantage. [/QUOTE]
