Trouble catching raid boss

Today I caught a 1595 Psychic (hidden)/bubble beam Suicune that I'll max out soon as I'm done typing this

Just solo KO'd a Magneton (took it out with one mon). Not too hard when he has Zap Cannon. Only had to dodge two of them to make it without getting KO'd.
Caught him just fine, although it took a few great hits to get it done (pinap).

No. I soloed a Machamp. No problem. Sometimes the random number generator gods just don't like you. Tomorrow will be a new day. And the RNG gods may like you tomorrow. Just keep playing. Success goes to the persistent, but especially the persistent with talent (which does not include me).

Just soloed a Scyther, and yeah, caught it with an excellent curve throw.

it's all chance. I'm 8 and 21 with Entei while using Golden Raz and Excellent shots at least 50% of the time. I'm 6 and 6 currently with Suicine and I have not used 1 berry.
