[QUOTE="KH_Outdoors, post: 3094691, member: 123559"] Great question! The 250's are going to be listed as a 1:9 minimum. And the 225's will be listed as a 1:10 minimum. Initial testing with the 250 grainer's were done with 1:9.3 & 1:9.4 twist barrels and they in fact did stabilize. That said, mono's typically like being spun hard. I just ordered an 8 twist Carbon Six barrel to have a custom throated 338 Norma Barrel spun up. Guessing that will be done this fall for a winter project. [/QUOTE]
