I apologize to everyone for not contributing much lately to this forum. Hopefully this winter that will change and I will be posting more on my paper patching with 416 Taylor. Last spring tried 66 grs of 3031 under a 330 gr round nose cast .410 of wheel weights -dropped into ice water, wrapped with 2 layers tracing paper dipped in water with a little Weldbond white glue added. CCI 250 mag primer. Necked down .458 wm brass, then fire formed with regular jacketed load, then left un-sized for reloading. Placed over powder wad of circular disc cut out of writing tablet paper -- diameter of inside of brass below neck. Then placing small tuft of cloths dryer lint over to protect base of seated bullet, and slightly compress powder. Not sure if I needed the small disc of paper to help keep powder/gases from base of projectile, will try some further loads without. It is a pain trying to not badly wrinkle or damage the disc of paper through the neck of the brass while seating over powder. At a full 100 yards my first 2 shots were 1 1/2 inches apart -- the third shot opened up-- third round was seated a little deeper. Should also point out my 416 Taylor has a muzzle brake. My guess rounds as being approx. 2500 to 2600 fps. --from 27 in bbl. before brake. Hopefully someone familiar with this round will add their best guess to fps. All comments welcome. Also add I use the traditional beeswax-vaseline lube on pp.
Will try to get some more testing done shortly. ps --Mr moderator if you could please add 416 Taylor to my title as appears I cannot edit title myself -- thx Bob.
Again everyone thanks for their tips/experiences shared over the years.
