430Man,

Nice shooting! But those are perfectly good AA hulls you're ruining! (Those were my favorite to reload in 12 and 20 ga - best hull life and crimp consistency)

It looks like you've got her dialed in - What load are you shooting out of the JRH?

I use a 440 gr boolit I made a mold for, 29.5 gr of 296 and a Fed 155 primer.

Nice shooting.

That particular load probably zips along at 1,300 to 1,350fps.

I would think you've probably been successful at keeping the rabbits away from your wife's flower garden with that load.

You might want to try 375 gr. Xs. My .500 S&W Raging Bull shoots them in unbelievable groups. Took a brown bear at 129 yards with them. 350 gr. Speer FPs are a good mild recoil round than is wicked on deer.

Did you have Leupold add that target Turret to that 4X -M8

If so how much was that??

that's "scary good" Whitworth. How's the recoil and what length barrel?

This is what we found.

Dang Jim - you really ought to work on those cast bullets of yours. It appears that your bullet sheared completely in half!

My BFR 500JRH has a 6" barrel and when shooting a 440 grain boolit at 1,350fps it chews on my trigger finger 1st knuckle pretty good with iron sights. Putting on the scope base, rings and a Leupold 2.5X8 scope will tame it down some, so I don't get chewed on, but it's still plenty stout at that velocity.

Jim, does your 440 grain boolit have a shorter shank than most other makers? I find the 440 grain boolit to be about max length for the JRH case due to case taper but just a slightly shorter shank would really help out in several ways (I think). Most of my 440 grainers have a 0.507” shaft. Maybe I need to shoot plain base and leave off the gas check?

A 500 grain Hornady XTP chambers like a charm and will keep rabbits out of the flower garden.

No, that scope must be close to 50 years old and came with the turret. I wish I had one for windage because I have spin drift. Sighted dead on at 50 and boolits hit a little right at 100 and a little more at 200.
I remember driving from Cleveland to Akron to buy it at a distributor with a retail store in back and a dealer store up front. Been a LOOOONG time.
This gun will get an Ultra Dot soon.

I have had cast boolits age expand for my .475 to .478". I size .476" and had trouble chambering after they expanded. I had to size the boolits again. See if it is the boolit going into the throats or the brass.

If you & Whit use that load for “plinking” my hat is off to ya – after about 40 rounds at that velocity I’ve had enough and back off a little. Great hunting load for rabbits but my trigger finger takes a whopping at those velocities.
