You know I love the completed A-Bolt. But I love a mod70 action much better than a browning. I like the CRPF winchester has out and wouldn't hestitate to say it would perform as good as a push feed with spring loaded extractor from browning. All the ones I have shot in WSM hasn't had an issue. And I have been looking for it on the winchesters. Accuracy is so so on US repeating arms in WSM. Some are incredible, some are horrible. Seem to come in two different varietys only. All had rough barrels. I have not loaded for a A-Bolt in WSM. But can't see a reason why the action won't cycle the sharp shoulders.
