(See note on Powders below or read all about various Powders.)
Bullet is .277″ diameter. Due to different barrel lengths, type of bullet, seating depth, primer type and other factors, you may not get near the FPS charted. It is just a guide and the reason you should start under these charges and work up.

Discussion: The .270 and 7 MM are fast, flat trajectory bullets and loads. IMR 3031 is a faster burning powder than IMR 4895, so you use less of it for similar volocities. I have listed powders of Hodgdon, Alliant and Accurate also. Use which ever you have handy. Slow burning powders generally work better in longer barrels and heavier bullets. .270 Cases will stretch, especially with hot loads, and you definitely need to check each in a case length guage and trim off excess brass. Of course, discard any cases that show a split anywhere on the case. For hunting at long distances with an unobstructed view, you should choose the spire point with a soft lead tip. For hunting at shorter ranges in brush, as is common in the woods of Alabama, you should choose a round nose bullet. They are less easily deflected and/or deformed by brush that you may be shooting through. The .270 is really better for long-range, open country and not so much for the brush and woods. But any clear shot with it is deadly.

There are a number of other high performance bullets on the market. The “boattail” is a very good long range target match bullet. It has very good wind performance. If you are shooting for precision, you should weight each powder charge and put exactly the same amount in each case. Each case should be exactly on specs and the bullet should not be crimped into the case. (These bullets don’t normally have a crimp ring anyhow)
