[QUOTE="Tragik, post: 2823035, member: 105059"] What do you estimate the muzzle velocity to be for 20 VT with 55s? On that note, I had a website that I saved a week ago that had 221 fireball lapua in stock and now it's sold out. Bummer considering it's discontinued. And after the research I've done, 20 BR is too overbore. I may circle back to the 20 Beggs which is what I originally had planned on when I first started researching this a few weeks ago. I'm seeing load data of 25 grains (VV N133) with good results, which is less than my 204 ruger runs on. Granted it's a much heavier bullet I'd be using with the Beggs that will negatively affect barrel life. Obviously barrel life has many factors at play but I'm just looking for a very rough estimate for a 20 ARC or 20 Beggs. I generally shoot in 40 degree to 70 degree temps and take about a min. between each shot (but every dozen rounds or so I try to shoot 3 or so as quickly as I accurately can with a bolt action). After the 9th or 10th shot, I usually pause for 5 min. Rinse and repeat. And we'll shoot eggs anywhere from 250ish yards to 600ish. We shoot paper to 1K. [/QUOTE]
