Not a Happy Chappy!

[muffett.2008]

Took a couple of rifles to the range today to zero the scopes.

Running a soft load that equates to aussie milsurp ammo to get them squared away, MF56 with an average of 2430fps.

My loads were 38.5gr AR2206H pushing a 174gr. Sierra matchking, in the No.4T they put out ...

1. 2420 lo 2420
2. 2443 hi 2447
3. 2444 av.2438
4. 2438 es.26.91
5. 2447 sd 10.77 group 1.691

The No.1 HT gave me a slightly slower speed with an annoying spread.
1. 2350 lo 2332
2. 2351 hi 2474
3. 2474 av 2382
4. 2332 es 14.20
5. 2402 sd 57.76 group 1/2 wide but vertical spread of 2.5in. in keeping with the varying velocity.
Still in all I was reasonably satisfied, will just need to up the load a bit for the SMLE.

But that's not my swearing point, 2nd last shot with the HT, the optics looked like it had a light oil spray, ignored it and pushed the last round downrange, now I had a more defined crazing pattern on the rear lens, not oil after all.

So a better look when I got home looks like rear lens seperation, I hope thats all it is, but there is a bit of crystalization that may be shattered/chipped inner lens, will not know for sure until I strip it.
The rear lockring is supertight, this will be fun, My fancy scope ring tools don't budge it, I may have to knotch the edge and use a collet type spanner........any suggestions?
