Just thought I would share this with you. I have been testing loads in the new rifle and have thus far shot several good test groupings. I have found at least one bullet and some primers that it doesn't like. Anyway today was a new experience. The target I will try to include was actually fired off the bench with a bipod attached. It appears to be only two shots but it is actually three. I fired a couple more good groups off the bipod and then the .300 started getting the best of me. My shooting partner was also shooting a couple of his .300s off a Caldwell Lead Sled so he offered to show me how it works. I took my rifle over and inserted it into the cradle, got the crosshair adjusted on the center of the target and lo and behold, I received no more recoil than from my .22. Now that is the way to test your ammo. This is the way to find out about bullets, primers and powder. It takes out all the variables---mainly me. The .300 is sort of mean to me off the bench and bipod, but that Lead Sled turned it into a ***** katt. I guess the main thing it will eliminate is the flinch when testing a bunch of ammo. I will have one tomorrow. I know it is not the way to develop marksmanship ability, but it sure does help when developing loads and getting a scope perfectly zeroed. I just finished loading my next test run and will try them Thursday on my own Lead Sled. I will be shooting 165 gr. Accubonds over 83 grs. of H1000 with CCI Large Rifle, CCI Magnum and Winchester Magnum primers. The WLRs and Fed 210s did not shoot good groups. I will also load some test rounds with 180 gr. Accubonds and 80 grs H1000 tomorrow.
