I am quite sure that I could bump up to full house loads without an issue, the only problem is that there will be some major impact differences and re-zero would be a must. Not normally a problem but for some reason him and I shoot P.O.A. about 4-5" different with this load meaning that I would want him to shoot the load too. Now that it gets dark an hour after school gets out that is pushing it. I am really kicking myself for not thinking of this but he is REALLY accurate with the current load and I want to be comfortable with his accuracy and would want him to shoot the new load.

Anyone know how the energy would compare with the 100 grain .243 sierra my daughter shot her doe at 100 yards with being pushed by 27 grains of IMR 4198?
