Thread: 303 wildcats??

I have one, I made a few years ago, 35/303 I used a 35 Whelen reamer, it was reamed into the 303 case length, all work was done at True Flite, fitted red and green fibre optic open sights.
I cut the bottom off the 35 Whelen die to match 303 case length, for reloading started with .35 win loading data, I use cast lead bullets for fire forming, load with Hornady 200 grain FTX and Speer 250 grain.
It took about half an hour to adjust the magazine feed lips and spring to get it to feed reliably. This has made an awesome bush rifle,

Whats your final loads like??

Rough speeds? I was thinking AR2206H should be a good powder for one?

At 50 yards with open sights was just over half an inch, yes I used 2206H, 44 grains for the 250’s @2250 fps, 48 for the 200’s @2500 fps YMMD
I guess a 358 Winchester reamer could be used as well with the 303 brass to make a rimmed 358 Winchester
