Accurizing the 336

I have a nice old Marlin 336A (long barrel) in 30-30 which shoots just OK for what it is I think. That means I can count on it to stay in 2 to 2 1/2 MOA with loads it likes. I've seen other Marlin lever actions do much better, such as one in 45-70 that stayed in about an inch with the bullet weight it likes. Is there a way to accurize the 336? Except for proper functioning checks and load development all I've done is to use metal foil under the forearm to remove a bit of wobble. Accuracy and consistency were unchanged. It would be fun to do, and maybe even rechamber to a peppier round. Any ideas gratefully accepted.
 
I will recommend the book "Accurizing the Factory Rifle" by McPherson. It has quite a bit of info about lever actions. Strengthening the buttstock attachment with a through bolt probably makes the most difference.
 
Thanks dbldblu

That sounds like a nice stocking stuffer.
A related question: Will the older actions (1950s) in 30-30 caliber accept higher pressure or larger caliber barrels? Also, what level of accuracy can be expected from the 336 with a good barrel and accuracy job? I hear boasts of MOA 336s, but have seen only one and that was in 45/70. Maybe that caliber isn't a 336?
 
"...2 to 2 1/2 MOA..." That's nothing to be ashamed of. Consistent accuracy is more important than anything else. Do a trigger job first. Then work up a load with different components.
 
A cannot answer your question about 1950's lever action and higher pressure rounds, I just don't know. McPherson claims that a lever action with the major flaws remedied should be as accurate as the average bolt action. I would not settle for 2-2 1/2 moa but then I like projects. I had a Marlin 45-70 that would put about half of its rounds into a 1 to 1 1/2 inch group and put the rest of them into a similar sized group 4 inches away. The buttstock attachment is what was causing that.
