I shot both my softer bullets and my linotype bullets again today. They are Lyman 31141 sized 0.310 and gas checked. Lubed with NRA 50/50. It was windy but I had my wind flags today. Groups with Linotype were no better than before but I did not change anything so that is no surprise. I was hoping for fewer fliers because I was more careful loading them, I think maybe it is a problem with my bench technique. These rounds have more recoil than my other bench rest guns. We are talking 172 gr. at 2000 fps. I am thinking of moving away from free recoil.
The softer bullets (COWW with 1% tin) shot better at this higher velocity but some still show a bit of keyholing.
I am not reporting the groups sizes as they are not much changed but they are mostly between 1.5 and 2 inches except the group with the wild flyer.
