Furthermore, it is quite possible to drive 120 grain bullets at 3000fps and the 140 grain bullet weight at 2800fps from 24” barrels with long case life, using either of the above powders and careful load development. There are a vast range of projectiles for the 6.5mm fan to choose from.

29 Δεκ 2011 · Back your loads down to 2800-2850 and have a long barrel life and exceptional accuracy while doing that. Those bullets have plenty of BC to get you out there competitively at those speeds with no problem.
23 Ιουν 2020 · In order to determine the accurate barrel life of a rifle, we can use a barrel life calculator. The most widely used barrel life calculator on the web today is known as Mike’s Spreadsheet , which uses five variables to provide a good accurate barrel life estimation.
Re: LAPUA 6.5 X 55 Ranger1183, What sort of barrel life are you getting? A good shooting buddy runs 6.5x284 in one of his F-class rifles but only expects just over 1000 rounds as a barrel life for the prime accuracy, normally has 2 or 3 barrels made up at a time.
11 Ιουλ 2024 · 6.5×55 vs 6.5 Creedmoor: Barrel Life. This is always guesswork, and probably the best estimate is 2,000 to 3,000 rounds of first-class accuracy for both cartridges.
