[QUOTE="Buffalobob, post: 90456, member: 8"] Bullet warmer I am using RL22 in my 7Wby and it was developed in 75-80 temperature. As Sewhat says at 100 degrees I had to hammer the case out of the chamber with a cleaning rod. Last week it was about 40 degrees when I was hunting, I keep rounds in my tee shirt pocket for long range and I got bored and dialed a rock at 796 yds and pulled out a warm round and quickly fired. I did it again because it was so much fun. Both rounds were exactly on. Today was about 25 degrees and I just got home from hunting. What I did for today was take a brown cotton work glove (you know the kind that cost $1.99 and lasts about five minutes) and poked some holes in the wrist cuff and ran a boot lace through the holes to make a necklace. I put one cartridge in each finger and two in the thumb of the glove and dangle in inside my shirt next to my skin. For close range I have a cartridge in the chamber and some in my pants pocket. Just my guess but the ones in the pants pocket are at a temperature of about 55 degrees, the one in the chamber at 25 degrees and the ones in the glove next to my skin are about 85 degrees. I worked on this temperature issue a bit today. So I think those estimates are good enough that you should not believe that bullets in your pants pocket area "warm". Once you put a warm round in the chamber you must fire fairly quickly or it will cool off. I will post a picture of my bullet warmer when I get the roll of film developed. To avoid patent infringement I suggest you can use a sock. I had a buck chasing a doe at about 840 yds in a scrub brush field next to the river but he was intent one chasing and was in and out of the brush and never got still and finally the light gave out and I had to give it up. There were some resident Canadian geese down on the river at ranges from 700 yds to 1050 yds and I was so badly tempted I could hardly resist. Seems like all of the fun stuff is illegal. Good luck tomorrow . I hope to get back out on Thursday or Saturday. [/QUOTE]
