I'm considering getting a lead sled but I see recommendations by posters that having over 25 lbs of lead can cause damage to the firearms & scope. I can understand how the stock could be damaged because the recoil of the barreled action is pushing where they are mated to the stock and that push goes through the magazine well and grip as it pushes against the buttplate. So that if the buttplate is held quite solidly, the force will be to compress at the weakest points which would be a splitting of the magazine well and/or grip. I understand that, but how could the barreled action being heavily supported cause damage to the scope? It is along for the ride with the action and if the action is held firmly I don't see how it can be damaged. However, just because I don't understand something doesn't mean it isn't so- So, those more knowledgeable of the issue than I, please explain. Thank you.
