I have owned and hunted with a 1963 built M88 in 308 WIN chambering for the past 25-26 years. It is one of my favorite deer rifles, maybe my favorite. I have not messed with the trigger, but it did take some time to get to know it well. Two bits of advice from my experience - get an extra magazine or two if you can find one - amazing the difference a new mag can make if your rifle doesn’t feed well. Secondly, mine won’t shoot a 150 grain bullet (factory or hand load) worth two cents (3 MOA) but with one hand load will consistently shoot 1 MOA with a 165 grain Interlock (I use IMR 4064).
Wisners will sell you a replacement magazine forModel 88's in .243 or .308 Win.for $50.00. For $60.00 you can have one with the Winchester logo. He used to sell followers and mag springs and I bought and used a couple but they are no longer listed.
If memory serves, he bought the original tooling from Winchester.
