The Barnes bullets are much too long as are the 350 gr. Sierras and such. I did use the 325 Speer SP, but nothing heavier would fit and leave any room for powder. I believe the 275 Barnes would be too long even if it was seated to the bottom of the case.
I didn't shoot any jello and was only able to keep the gun for a short time.
