Well, I've read two very opposite reviews of the Limbsaver doohickey.
For those who haven't heard of it, it's a rubber donut that you slide along your barrel until it dampens the harmonics. It's a clever idea, it's inexpensive - and it's both bulky and ugly as sin.
It also didn't seem to help in at least one writer's opinion.
I think if I had bstern's rifle, I'd find a good load about 5% below max and call it good enough.
What's good, and how do I find it? "Good" for THIS rifle is a load that has low extreme spread across a lot of velocity readings, and shoots consistently into 2" or less (this is a deer rifle). Since this is a lightweight, skinny barrel gun, I'd shoot three-shot groups mostly, with longer shot strings being done in very slow batches of two shots at a time - lots of barrel cooling time between the twofers.
Why 5% below max? Because accuracy is more important than raw velocity, because recoil does matter, and because slightly reduced loads are often more consistent.
