[QUOTE="Deleted member 46119, post: 1121699"] :P LOL I have 2 300 RUMs at the moment so experience goes with the data and opinion. To directly answer the OP question, you will loose ~25fps per inch. That is well established. In actual, a little more a little less. Depends on the barrel and some other details. If you load something like a 190 Berger Hunting VLD, which is dead middle of your range over Reloader 25 your efficiency, as in powder burned in the barrel will say quite reasonable. As short as a 22" barrel is capable of 3100fps with the above combination at the same pressure a 26" should be more like 3250. As Jokester (just pulling your leg, keep smiling) points out and I whole heartedly support: make, take, bake what YOU want. [/QUOTE]
