[QUOTE="codyadams, post: 1446108, member: 87243"] I use reloder 26 exclusively now in my 29" barreled .260 AI, and it is giving outstanding performance, significantly more than H4831sc. I never tried Reloder 16. I pressured out with H4831sc at 2980ish fps, somewhere about 48.8 to 49 grains. However, with Reloder 26, SRP Peterson brass with cci br-4 primers I'm getting 3040 fps, 9 fps E.S. and 3.8 fps S.D. using 49.5 grains with it seated to 2.930 OAL which is .010" off the lands in my rig. I have got up to 3100 fps with 51 grains with the beginnings of pressure signs using Lapua brass, but I havent worked up loads to max in the peterson brass. With the 140 Bergers, I was using 49.1 grains and they were going 3070 fps, and worked up to 3150 fps before pressure signs appeared. This is in a fully broke in (1200 rounds) 29" krieger 4 groove 8 twist barrel. To the OP: THIS IS IN A .260 AI. Do not duplicate my loads. From what you said, I would stop around 48.5 grains. Any time I have had any kind of bolt lift or any other signs, primer pockets don't last much longer, and your hivh pressure. Besides, 2875 fps in a 24" standard .260 is dang good, and I would say your at or just below max there. In a 28" barrel, you would be going about 2950-3000. That is a hot load.... [/QUOTE]
