I was looking for boolit for my 44 Rugers in 300-310 grains weight range, and as far as I could see, there is no active or pending GB. Since we are talking about heavy boolits, intended for large game, IMHO, LBT with large meplat dia and gas check for better accuracy and to eliminate leading is the way to go. Yeah, we love our SWC designed by Keith, and we shoot these more than all others combined. However, they are not the only game in the town. I would strongly suggest to read this thread first http://forums.accuratereloading.com/eve/forums/a/tpc/f/2911043/m/2391097721/p/1 and look what bfrshooter (he is our member here, 44man) had done with right boolit.
Now, pay attention to something interesting on his boolits; he incorporated into nose design a conical area that has the same angle as forcing cone on revolver barrel. The point is that our standard Ruger, S&W, Colt, etc. revolvers do not have perfect cylinder-to-barrel alignment, and noted cone on the boolit helps to align it while entering the barrel. Since Rugers have 5° (included angle) forcing cone, I started thinking about LWN boolit that will have same forcing cone angle. I am aware that 11° is accepted as the optimum angle. However, in less than perfect revolvers for us ordinary mortals, 5° angle might have the edge if right boolit is used, because in the most critical moment, when boolit hits forcing cone, contact surface more than doubles when compared with 11° one, thus reducing boolit deformation.
Here is my version of noted boolit for Rugers:
http://i1096.photobucket.com/albums/g337/Onty50/44-310-LWN-GC-1.jpg
Nominal dia; .432
Weight; solid FP using WW, with GC: 310 gr (suggested)
Meplat dia: .340
Crimp to meplat: .445
OAL, with GC: .845
As for the weight, I would not go less than 300 grains, however, if majority thinks we should go bit more, I am open for such option, as well as for change of any other design feature.
I am thinking about both, solid FP and HP Cramer mould versions, in brass blocks. Miha agrees to make these ones.
Please, take a look and let me know what do you think, should we go for it? I hope that 44man will chim here and let us know what he thinks.
