Strongly disagree. The original Model 1903 rifles fired the 220 grain bullet with proper load without problems, and they did not even have a single stock bolt. There is no reason why such loads would cause damage to an otherwise sound Model 1903. See 148Infantry's comments, above.No and No. Sure you can do it but its not the issue ammunition for that rifle and you will damage the internal bedding of the original stock on the rifle. A box of proper 150 gr bullets is but 30 dollars at best ...far cheaper than replacing a wood butt stock. So the answer is Yes you can but its dumb as dirt to do so.
