.303 British
Anyone have a favorite load for this cartridge?
Is there a parent cartridge that this was derived from? My "new" son in-law just picked up a pristine .303 from an old timer who was walking into a local gun store to trade in his WW II souvenir.

I have this 150 Gr load for you. The factory loads were for 174GR FMJ FB but you can't find FB bullets in 174/180gr except for RN types . Some Enfields (mostly with 2-groove barrels) don't like BT bullets so I go with 150 Gr flat bases for my reloading.
The case is unique, but if you need some brass I can probably point yo to someone with some to sell, not me, I'm collecting, rather than dispensing. 150 Gr Hornady HP-FB # 3120 PPU case 38.0gr IMR3031 Fed 210 primer 2500 @ 10'

I would strongly advise that the bore be slugged to determine what the bore diameter is on that gun so you know what will/won't work as far as bullets go. Enfields are rather notorious for variation in bore diameter. For brass, try Midway.

Hi,
I bought new winchester brass a few years ago. The old original brass has the two flash hole primer that make reloading difficult. I used blc-2 powder behind a 135gn hollowpoint made for the .303 (which is actuallu .311) |

My pet load is a 160 grain hardcast lead slug (http://www.midwayusa.com/viewProduct...tNumber=339539) which throws a little large behind 16 grains of 2400 with compressed grits as filler. Smells good as you shoot it .
All the jacketed bullets I have bought I have measured with my digital calipers. Sierra, Speer, Remington and Hornady have always come up slightly undersized, .309-.310. The only bullet that measures correct (.311) is the Barnes all copper bullet. |

The .303 was developed in 1889. To my knowledge, it's an original design and not derived from a parent case. However, this may be debatable as there were many rimmed military cartridges when nations first adopted bolt action rifles. Interestingly, the American .30-40 Krag is based on the .303 British.
