Reloading The .243 Winchester Rifle



(FN=Flat Nose, SP= Spire Point, HP= Hollow Point, RN= Round Nose) JHP= Jacketed Hollow Point, FMJ=Full Metal Jacket)

Loads for .243 Winchester Rifle:

(Note: These are near maximum loads, you should use 10% less to start.)
(See note on Powders below or read all about various Powders.)
Bullet is .243" diameter. Due to different barrel lengths, type of bullet, seating depth, primer type and other factors, you may not get near the FPS charted. It is just a guide and the reason you should start under these charges and work up.

Discussion: The .243 is fast and flat. I have listed powders of IMR, Hodgdon, Alliant and Accurate. Use which ever you have handy. Slow burning powders generally work better in longer barrels and heavier bullets. .243 Cases will stretch, especially with hot loads, and you definitely need to check each in a case length guage and trim off excess brass. Of course, discard any cases that show a split anywhere on the case. For hunting at long distances with an unobstructed view, you should choose the spire point with a soft lead tip. The .243 is really better for long-range, open country and not so much for the brush and woods. But any clear shot with it is deadly.

There are a number of other high performance bullets on the market. The "boattail" is a very good long range target match bullet. It has very good wind performance. If you are shooting for precision, you should weight each powder charge and put exactly the same amount in each case. Each case should be exactly on specs.
