I've had very good success with these bullets in other guns and will by trying them next week in my Ballard rifled 1895 in 45-70. I'm tempted to try them in my mirco groove Marlins just to see how they do. I have a 336 (30-30) that I would very much like to try lead bullets in.
Anyone tried the Oregon Trail Laser-Cast or TRUESHOT bullets in their Mircrogroove barrels yet?
In the Laser Cast Reloading Manual (excellent) it states "Micro-groove rifles might take some load development for accuracy."
The bullet I'm considering is the 170g RN FP .310".
In the 44 Remington Magnum I'm consdering the 240g RN FP .431"

I've tried them, and they shot well, but not great. I'm sure with a little tweaking they'd do better, but I shoot mostly jacketed stuff anyway, and didn't feel like putting any real time into it. But I love their bullets, in hard-cast lead that's about as good as it gets. Both bullets you mentioned sound like good choices, but even though they're over normal groove diameter, I'd still slug the barrel to be sure.
"The gun has been called the great equalizer, meaning that a small person with a gun is equal to a large person, but it is a great equalizer in another way, too. It insures that the people are the equal of their government whenever that government forgets that it is servant and not master of the governed." (Ronald Reagan)
