I’ve been a reloader for over 40 years. I have never run into this before and have reloaded thousands of rifle cases over the years. Maybe some can tell me if this is normal.
My rifle is a stock Savage Model 11.
The new 260 Remington Starline brass length was correct straight out of the box and the first loads fired were mild. After firing, I set my sizer die to bump the shoulder back .002”-.003” so it would chamber easily. After sizing, I checked the case length and it had got .003- .004” longer. ( I know cases will get longer over time and need trimming. )
After each firing and sizing, the cases continue to get .003-.004” longer and I have to trim after only 2-3 firings. All loads are well below max according to all the manuals I have read and no signs of high pressure. Load is, 123 gr Scenar, 43.1 grs H4350, CCI 200, 2.280” OAL, 2890 fps avg.
I tried bumping the shoulder only .001” and neck size only but the cases still get longer. Trimming after only 2-3 firings on a case seems odd. Is this normal with the 260, or is it just with Starline brass?
