PCP BSA R10 Mk 2

I know that there are other BSA R10 Mk 2 owners out there. What did you get for shot count and did you try adjusting the hammer spring? If so, did you find that the adjuster was turned all the way in also?

I have tuned my R10 Mk2 to shoot .177 to shoot 10.3gr pellets at 917fps avg, 12fps ES and a 1.31%ES for 62 shots on the small aluminum cylinder. I have completely rebuilt it, and added a Huma reg set at 130bar.
I've read and heard folks say the original reg is good, but I fought mine so long, I almost got rid of the gun, and then had to make a decision, put in a Huma, or sell it. I'm sure glad I put in the Huma, it is a TOTALLY different rifle and now with the correct pellet it will hold a 6fps ES for an entire string. To say it shoots like a laser would be a huge understatement. The R10 is simply an amazing rifle.

This is encouraging. I have an interest in owning a BSA, but have yet to make the move.

Stephen heard at the IWA show that the R10 is being replaced by the R12 so availability may be limited in the future. R12 is a side lever.

If you find an R10 Mk2, used, I'd jump on it. I made a stupid mistake when AOA had a very nice used one on sale for $5xx, and I almost ordered it and then changed my mind, thinking I had too many pcp's. What a bonehead move!
I tell you they are fantastic with the Huma reg. I could care less if it's bolt action or side lever they're great guns. I get 62 shots out of the small aluminum cyl, tuned to shoot just over 900 fps, I can't imagine how many shots you'd get if it was tuned down. A 12 fpe tune would have to yield something like 200 shots. My R10 is so accurate, that I'm thinking of making a forend block to fit a rest and using it for airgun benchrest.

I had one and it was a great rifle. I quickly put in a Huma reg and was shooting around 920fps with 10.5 grain Crosman Premier Heavies. I believe I was getting around 80 shots. I bought a 280cc bottle and was getting 135 shots. It loved 10.5 CPH pellets with L lot stamped on the brown box. I ordered a bunch more brown box CPH pellets and Crosman switched to M lot. Didn’t like those as much. I found the L lot pellets were pretty consistent around 4.50 head size and M lot pellets were around 4.53 head size. A friend of mine shots FT with the same R10 Mk2 and his likes Barracuda Match in 4.50 head size. I know, 2 random R10’s, but both liked the 4.50 head size. Worth looking into.
