i have about a 10 year old tc omega. Shoots great. I use 2 pellets 777 and a 250 grain shockwave w/sabot. My question is. Is it normal to have to push very hard on the rod to seed that sabot. I have marked my rod years ago when it was full seeded. Now I have to tap the rod with some thing to get it to the seed mark. I even run a brush through it between shots. I have to push on rod very hard to get it down to bottom mark. Or can I leave it about 1 inch off.
