Thread: .303 loads

I have a 14.6 inch barrelled carbine that delivers 2018 fps with a 194 gr paper patch bullet over 44 gr AR2209. Paper patched bullets are faster than jacketed.
My 1902 Lee Enfield fitted with a No4 barrel gave me 2395 fps with Speer 180 gr RN over 38.6 gr MR200 (Somchem powder) and 2690 fps with 150 gr Hornady spire points over 40.9 gr MR200.
I load my No4 to around 2400 fps with Highland 180 grainers with 46.3 grs AR2209. This is a very accurate load in my gun. Pressure is mild.

AR2208 should deliver between 2650 and 2700 fps with 150 gr bullets and AR2209 should deliver up to 2500 fps with 180 grains.

I never get case head separation, even with full power loads.
