I have some 300 jacketed and 265 jacketed and 240 jacketed and 180 & 240 XTP and 310 lead and Lyman gas check 245 & a Lyman flat base 258 grain. I just opened the back up on a 245 LEE mold with a .436 reamer down to the lube grooves to make a little heavier bullet and ordered a .432 sizer to fit the throats in a RUGER S.R.H. and have a flat base. It is supposed to be here the 17th. I like the fact you can down load 2400 and Unique without a problem or mag primer but I do have mag primers for 4227. Here's one I opened up to .436 on the base and can size to .432-431-430-or .429 for better fits. This mold dropped at .429 but I elected to open up over sending back. This bullet has 2 crimp grooves and if it leads I can add grease to another groove or pan lube or powder coat. Lots of options. It works great in my buddy's Freedom arms as is but I am waiting on the sizer to try in mine.
