Background: I started a thread in the Rifle Forum about .243 versus .257 Roberts because I don't like the recoil from my .270 using factory loads. Based on that thread, I decided to try downloading the .270. I started a thread in this Forum seeking advice on which powder to use. Consensus was 4895. Today I shot my first centerfire rifle handholds.
Results: Encouraging, I think. Interpolating between loads from several sources, I used enough powder to get me into the 2700-2800 fps ballpark with the Hornady 110 grain bullet. This target was shot at 100 yards using my hunting scope, a Leupold 1- 4 set at 4 power magnification. I was at a conservation department managed range and had to shoot fairly quickly, so I think the vertical stringing is probably due to barrel heating. A 5-shot 2" group is acceptable for hunting, but I think I can shrink the groups by tweaking the load. Recoil was a bit more than I expected, but noticeably less than the factory loads, easily bearable.
Now, don't laugh. I got an estimate from Dillon Precision that it would cost about $150-180 for the parts needed to convert my 550 press to produce rifle reloads. I love my 550, I love Dillon, I am a customer for life. But Midway had the Lee Loader ("whackamole") on sale for $25 so I bought one, and these test cartridges were produced with the Lee. I am impressed that I could get this kind of consistency with that tool. I expect to be a very low volume reloader for this caliber, and the Lee will probably suffice.
Next step is following Olympus's outline for working up the most accurate load. Here's hoping I can post a better group before long.
Thanks to all for your comments. It has been fun reading and learning.
