The Whitworth thread

@freedomintheskies - Sir, I note that like many of the world's cleverest, most innovative and inventive, as well as good-looking and incredibly modest people, you are a leftie. Strange to relate, so am I.

You appear to be wearing eyeglasses that offer minimum protection against flying cap fragments, and shooting one of the most intensely high-pressure BP rifles know to man while doing so.

FGS get a pair of wrap-arounds and wear them when shooting this, or any, caplock rifle.

So far, medical science has been able to make pretty good replica rubber hands, ears and noses. However, all attempts at making a rubber eyeball have met with abject failure.

So please, do yourself a favour.

For those who wish to see the bullets that have been cast for the rifle, here they are. Fairly self explanatory. Larger lube grooves and longer bullet length on the Pedersoli mold and heavier too, at 520gr vs. 475 with the Lyman.
I've not shot the Lyman bullets yet, but may have a chance tomorrow. Actually, I have not shot enough with either bullet to offer up a comparison- Yet. The only thing I can speak to is the quality of the molds. Both are excellent quality and worked very well right out of the package. I used a tiny bit of graphite spray lube on both molds to aid in the release of the newly cast bullet though. Other than that, it took about 4-5 pours to heat the mold enough to get a proper fill out of lead and then it was just awesome sauce!

He makes amazing paper patch molds but the Whitworth was a singificant challenge for him to program the hexagonal twist on his CNC. I haven't seen the mold or the bullets yet but Mike is raving about it and he has bought a lot of very expensive molds from elsewhere and wasn't completely happy with those. Here is Rick's buisness card.

The hexagonal bullet that Balasz Németh is shooting is either the from Leo Kranen three-piece mould, around $400US ten years ago, or the equally pricey Romero mould from somewhere in the Eastern part of the USA.

You can save yourself a load of trouble -IF you want to shoot hex - by making contact with the Polisar Brothers in New Mexico. Their 500gr swaged flat-base bullets really are too good to shoot.

Sir, there is a gentleman of my acquaintance who is in exactly the same position as you are with regard to shooting a new Whitworth. He lives over near Peace River in BC.

Would you like to make contact with him?

Today I received the test tubes I had ordered a while ago. They will go in the "Rodney Dangerfields' range box" to make those snappy 1 1/2 minute reloads go even faster! (LOL)
The tubes are plastic and came with itty bitty corks. They look sort of cool and will hold 10 ml or about 110gr of black powder. Hoping to get out this Saturday to 200 and 300 yards with the Whitty. I'll also try to get the chrony out to see what sort of mind blowing speed this thing will develop.

[FONT=wf_segoe-ui_normal]A quick update on the new bullet mold from Rick at Kal Tool & Die:

[FONT=wf_segoe-ui_normal]Hello Dave:


Yes, I do have a "Polygonal" bullet mould for the Whitworth rifle. Single cavity, "Base" pour design, 550 gr. (97% Pb / 1.5% Sn / 1.5% Sb) 0.440" across the Flats, 1.375" OAL.
And, it does have the correct 1:20" Helix.

These bullets are designed to be Paper Patched to 0.448" - 0,449", using 0.0018" - 0.0022" patching material.

After a year and a half (off and on) and a lot of sleep less nights, I finally have everything at a point where I will be offering these moulds for sale. But, I doubt I'll have any available for another month or so.

Price has not been set at this moment. It will be affordable, there's a lot of CNC machining involved with that design. And I need to do some more "Time" studies before I come to a final retail cost.

Give me couple of days and I'll take some picture of the bullet and forward them on to you.

Regards.

On the home front, I had the rifle out to the range yesterday and fired 20 rounds from it at 100 and 300 yds., firing both the Lyman 475 gr bullet and Pedersoli 530 gr bullet.
The nod definitely goes to the Pedersoli bullet, but to be fair, they have probably calibrated the sights to work with it. At 300 yds. the difference in point of impact was significant, with the Pedersoli bullet impacting pretty much as point of aim and the Lyman bullet impacting about 3 inches low. The powder charge was 65gr BY WEIGHT or 70 gr. by volume. Charges were weighed to the .1 grain. The powder was Goex 2F.

More to follow.

Just wanting to provide an update.
First of all, I was able to get my paws on some GOEX FFF powder. I measured (weighed) out some charges of 60 gr. The load is enough to get your attention when it's touched off. It is also pretty darned accurate. Also of note, the point of aim at 100 yards was pretty much matched to the point of impact, so that's another bonus.

I also took a couple minutes and dug around in the backstop for a spent bullet. Happily, I was able to come up with one and it did indeed show signs that it bumped up to take on the hexagonal shape of the barrel.
