Very nice and most useful rifles here Gents.
Mine is a little RB Rodda top lever hammer rifle with rebounding locks and 26.5" fluid steel barrels chambered in 303 British, 215gr Woodleigh Weldcores at 2168 fps have shot through every deer or pig I've pointed it at, extremely accurate, point and shoot to a dead 100 yards.
IMHO every double rifle needs a solid load, with none available for my rifle I did a little experimenting, FL size your 303 British brass with expander ball/button removed from the die, seat 210gr CEB flat nosed #13 copper solid to just below front driving band on preferred powder charge, crimp case mouth over front drive band.
I have fired five 215gr Woodleighs from the right barrel front trigger and have yet to have the solid slip forward any at all under recoil, that bullet runs 2220 fps with the same charge of powder for the 215 Woodleigh and also regulates beautifully.
The CEB flat nosed copper solid will shatter any bones it hits at the hip/pelvic region of any large African Antelope/Zebra/Wildebeest etc, the bullet will then punch the liver, range on up and through the lungs, on through the heart and most likely exiting the chest/neck of the animal, and all that's after the animal turns to run from taking a slug hole punch from the little 215gr Woodleigh first shot.
I shot that 210gr CEB solid dead straight through a standing and live 18 inch red oak tree here at the farm at 20 yards, in and out, unreal penetration, animal tissue, bone, hide, fat, etc can't catch that one.
Not to sidetrack the thread, just wanted to put this out there in case any other 303 British fans are reading.
