After having some issues with my CVA 35 Whelen, and deer season right around the corner. I went to sight in my 35. It does fine at 25/50yds, but it is all out of wack at 100. While i was there, my cousin brought out his 44 mag. Myself and my G/F shot it and was instantly hooked! Found one this past wednesday and plan on sighting it in sunday (with a 3-9/40 Nikon Prostaff) that i am going to take off my 35. I was just curious as to where you all are putting these o-rings and if its that important. I would really like to go sunday and out shoot him right out the box,lol. This gun is brand new and i plan on shooting it before i go to his house. Thanx for any info ;o)
