PVA is still perfect for a worn out centre. I'm imagining the OP drenching his boss with water in the house
LOL. Crazy I may be, stupid, not too much (I hope)
I live alone, so shooting in the house is not as stupid an idea as it may sound and allowed my to get my archery fix through the cold, dark winter nights
It's not so much the center of my target as the sides. I shoot from the kitchen extension, out through the kitchen door towards the hall door. A distance of 9m. I shoot recurve and pull 41# on my fingers. I shoot at a 3 spot and shoot rounds of 6 arrows, 2 per target. I do however shoot for groupings. I am as my forum name implies new to archery (3 months) and being able to group in the yellow is how I judge if I am improving. My 3 spot would be to the right of center on my boss.
My boss is an Egertec and was only bought just prior to Christmas. I rotate my boss for each session so I don't constantly shoot at the same spot each time and I shoot between 120-180 arrows per sesion and would shoot 3-4 times per week (along with 2 club nights). I am finding my arrows coming out the back now up to 3 or 4 inches.
I notice that at the back of the target, it looks like the straw rope has broken. Imagine you took spaghetti with one hand on each end and bent it. I also notice that after a session there is quite a bit of straw on the ground and it seems more than I see under the bosses at the club on club nights, and the club bosses could have 2 or 3 folks shooting at them, some with high poundage compound bows for 2.5 to 3 hours/twice a week.
As I said for the past 2 months my boss has been inside the house in the kitchen, and though not right beside the radiator, it's not miles away from it either. The club bosses are also stored indoors, though in a storage room in a schools sports hall. The club bosses are the same Egertec model from the same supplier. So I am wondering if the heating might have adversely affected my boss and the best way to prolong it's life.
Weather is not too bad today, bright & sunny, so I might bring it out the back throw some water over it once I finish shooting for today and see if that helps.
Thank you all for your responses so far
