[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.[/FONT][/FONT]
