I went out tonight and did a bit of bullet testing into wet newspaper. I had 5 bullets on hand to try out of my 7 RM, 140g Btip, 150g core lokt (factory), 162g SST, 168g VLD, 175g grand slam. Now my testing isn't the best, but it sure gives me an idea to say the least of what to expect. I soaked newspaper and put them into a cardboard box and shoot into at 100 yards. Theres my glorified bullet testing. Well I had a bit of a problem. The idea was to shoot the 162, 168, and 175 at one box, and the 140g and 150g into the other box. I wanted to see how they penetrated each other. Well after the first shot, the box split open and all my papers fell out. Great I thought. I rigged it up to where I could still shoot into, but it wasn't compressed as good so I thought maybe I would lose a couple bullets out the backside. The 1st bullet I shot was the 168g VLD. It lost the core, shed most of its jacket and weighed 47.5g out of 168. Thats good for only 28% weight retention, about average for what I am use to seeing with target bullets. 2nd bullet was 162g sst. It held 76.5g for 47% weight retention. It mushroomed quite nicely and the lead core was still intact. The 3rd bullet I shot was the 175g grand slam. Well remember how I said the 1st shot messed up my whole process, well this bullet must still be sailing somehwere because the newspaper didn't catch it. The 4th bullet was the 140g btip at 3250fps. It retained 63g which is good for 45% weight retention, about normal for btips. It lost its core, but was nicely uniformed mushroomed. The last bullet was the 150g core lokt at 3100fps (crono'ed). This bullet actually surprised me. It held 91.5g which is good for 61% weight retention. It expanded more then any other bullet except for the 168g vld, but held its core surprisingly. In my other core lokt testing with 120g 25-06, and 180g 300 WM, they did not fare to well, but if memory serves me right, back then I tested bullets at 50 yards, thats a lot more stress on any bullet. Here is a pic of the 4 bullets recovered, from left to right, 140g BT, 150g CL, 162g SST, 168g VLD.
