Forget where I saw it - RECENTLY - but Andy Larsson (Skinner Sights) just (begrudgingly) wrote a tips and tricks to accurately shooting a lever gun. It was spot on. I wish I could remember where I saw it, but if you are interested, let me know and I can ping Andy and get the article. They can be a trick sometimes. I also have the Rifle Accuracy book and it has a lever gun chapter, and tells how to relieve pressure points in a lever (can provide info if interested). And, as mentioned above, worst case, remove all the front end stuff/single round/hand on bag (not rifle)/cold bbl, and figure out the best load and then go shoot. Once had a 336 35 Rem that would group the first shot/cold bore/time after time/same target - into a 1" group. But if you shot 3 rounds, it would walk them 6" high by the 3rd rnd.
