I read one other user's review of it and he didn't consider it a tackdriver either. But you know what, a rifle doesn't need to be a tackdriver to be enjoyable to shoot. And eventually, you should run across a load that will perform admirably enough.
Some guns are just a pleasure to hold, carry and shoot with intrinsic qualities that just can't be quantified.
If the rifle fits and balances well, that alone can often more than make up for a lack of MOA shooting accuracy. That's what I define as being a gun's "shootabilty factor".
To me, a gun that is shootable is more desirable than a super accurate one that isn't as shootable.
Whether it's the barrel bedding or the load, the trigger or the sights, it really doesn't matter. As a matter of fact, sometimes the worse a gun shoots, the more like an original hand made antique muzzle loading rifle it usually is!
Reminds me of the Remington Model 12 pump action .22's. Some of them might not be the most accurate .22 pump guns, but they're classic and they work, so they're still very enjoyable to shoot! I'll just concentrate on shooting them at closer range targets, that's all.
Just keep experimenting until you find the most respectable performing load.
Don't you just love it that much more now?
