Until a few days ago I had never fired either round. Me and the grandson fired the new to us Tikka T3X Superlite in 6.5 Creed the other day an it was more fun then the other rifles we fired. Like my 8 pound custom .338, the 6.5 lb. Husqvarna 30-06 and the 7 lb. 45-70. Any way we enjoyed the Creed from the bench.
From what I have read both the .280 and 7-08 will kill any North American animal all day long and I see no reason for more power then a short action cartridge puts out for Texas hunts. Texas deer ain't huge, so why go big with a cartridge?
