good afternoon;
Overly optimistic? Need 375Weatherby cases. Given a very large number of 300h&h cases. Game plan was fire form 300h&h to 375h&h then fire form the 375h&h cases to 375 Weatherby.
300h&h cases, used 5.5 grain bullseye, filler to keep powder at base of case, fill case to mid-neck with grits, tight fitting plug of toilet paper. Fired in 375 Weatherby, case dimension did not change.
Any suggestions? Powders on hand: Bullseye, Red dot, Green dot, 2400, 4198, 5744. Have a Lee 150 grain bulleting casting mold.
Thx again for any input.

cases were annealed before hand. did use a 1\4 sheet of toilet paper to keep powder in place. tried resizing to 375 but did not work, even using a rcbs rocker press. did not compress grits
