My m70 featherweight hasn't ever been a great-shooting rifle. It doesn't much care for 180's. It doesn't shoot different weight bullets anywhere near the same location. The barrel heats up quickly and it doesn't group with a hot barrel. Load development has always been a struggle.
Up until recently, 200 grain Accubonds with RL17 at about 2725 fps have been the only load that groups consistently well. I had just about given up and decided to buy another box of those bullets and just have one load for the rifle. But I went ahead and re-bedded the rifle and tried some 165 Partitions that I found an old partial box of. Loaded up some RL15 and H4350 and hit the range. The top H4350 load, 58.5 grains, stacked all three into a perfect cloverleaf. But they only went 2780 fps. I only had 20 left and didn't want to waste the rest of them chasing more speed, so I came home and loaded them up.
So, I'm wondering, am I really ever going to notice the 100-150 fps I'm leaving on the table? I've also got some 168 Ballistic Tips left. I've pushed them to 3,000 fps with RL17 before, but never found a load that grouped very well. Do I try to see if they also group better at the lower speed? And if I'm gonna be shooting 165-class bullets at 2780, would I be better off just shooting 200's at 2725? Or, again, am I really ever going to even notice?
