Bit of a dilema, I have got a load for .243 using 100gn hornaday btsp bullets, 41.5 gns of IMR-4350 and federal match primers. my rifle has a 20 inch barrel. when put over the Chrono they come out at 2749 fps. which is just under the legal limit for deer. If I increase the load by .5 of a gn the group opens form just over .5 of an inch to about 2 inches. i need to get approximately 40 fps extra to make it a deer legal load. My friend shots with a 22 inch barrel and the load is well within the legal limit for his rifle. Any suggestions or loads would be appreciated.
Thanks in advance
