I ordered a Redding Full Length Type S bushing sizing die for my 300 Win Mag. To select the proper sizing button they suggest getting one that is 0.001" smaller than the loaded round neck diameter. I am using Lapua cases and they are measuring 0.3355 to 0.3363". So I got the 0.334" titanium bushing. But in checking my loaded round neck diameter I decided to measure some bullet diameters and found that the box of Nosler 200 Accubond bullets that I have on hand were 0.3075", not the 0.3080" that I expected. Does this matter much or would they still obturate adequately to avoid any gas blowby? Would them being undersized cause any accuracy problems? Thanks, Rufous.
