I’ve also had both an the R10SE was nothing but hassle. Under powered at around 10.2 with most pellets, constantly leaked, nowhere near the shot count BSA claim (I got about 100 per fill), several parts needed replacing under warranty and all this was in just 6 weeks of owning it.

During that 6 weeks it had 5 trips back to the shop and on the 5th, I asked for a swap for a new HW100.
The HW100 is better in every single area other than looks.

I would never touch another BSA product again!
