So I'm working up loads for a 300m competition, close to the ocean so winds are expected. So far 69g smk were good for a 500m shoot, however just yesterday hit a sweetspot with 80g nosler comps. Now the barrel is a 1-9 twist, 25g of r15 is pushing these suckers out at 2850 which is fast and pretty high pressure from what I hear. Problem is they pattern cloverleaf at 100. Now there is no range within a 3 hour drive that offers 300 m distance and the bush around here doesn't give more then 200. Any thoughts or experience if these will destabilize by 300 yards? Should we just abandon those and go back to the 69-75 weights to keep the spin correct at 300, or just pound a bunch of 80s out and hope for the best after the drive? Primers showing minimul pressure signs, bolts not sticky but sure showing burn on the cartridge mouth. Thoughts?
