What are you looking to do with it? Mainly a LR hunter or for longer range fun. Any way the stevens 200 can be bought for right at 300dollars and is just the old model 10 metal works add to that a Rifle Basic SAV-1 for 85 bucks with a 1lb pull weight or a SAV-2 for a 4oz pull weight and 146 bucks dollars . Then a stock upgrade as or if needed.
If a range gun the 243win can shoot with a 6.5-284 out to 1000 yards and give that barrel a AI chamber for a better preformance at a minimum of cost.
If its a hunter get that 7mm RM. Also good for 1000 yards with high SD bullets in lighter weights than the 300WM.
To bad they do not offer the stevens in a 6.5 cartidge like a 260.
