[QUOTE="HuntnPack, post: 1893386, member: 42721"] I’ll offer the following info to address your 70-120 rnd. “New barrel speed up”only question. I’m not recommending this as any specific break in process. That’s a different topic. you could try the following: 1) Shoot 100 factory rounds, (you may see a wider or erratic velocity increase with poor quality factory ammo.) don’t worry about accuracy too much at this point. Focus on Velocity. Document each shot. Or load up 100 starting loads with Preferred Brass or Quality Custom ammo to form. Take your time Here. Chronograph is helpful if you have one, to watch velocities increase, look for a leveling out around the 100 count, may require more or less. Do preferred break in / cleaning method, (If you so choose.) get familiar with the new rifle, make some scope adjustments, check that everything is snug. Then on to Load Development. 2) Do preferred break in / cleaning method, (If you so choose.) start load development right out of the gate, and address any bbl Speed up issues as you go, by tweaking your loads as you go (aka chasing your tail), until you see speeds Stabilize, If your barrel doesn’t speed up early on, Then you can continue with development. In either case be mindful of odd changes. You may find you end up at the same point at the end of either proactive or reactive process. I wouldn’t consider either as “wasting bbl life” but simply identifying & addressing certain variables. “Useful Load Development”. It may be a good idea to periodically Check where your velocity is running. make necessary adjustments. ( IF a barrel speeds up 100+ FPS you’ll have to address it somehow at some point ) here’s a sample chart of my 6.5 velocity 1st 80 factory rounds thru.
