First, i usually wait until after my first range session until i use JBs or any bore polish. UNLESS the bore is really tight or rough and i don't have any sabots that fit well. I might also use it sparingly as just a cleaner on a new bore. Maybe 20 passes and then finish off with Hoppes, MX or a good
non Teflon CLP.
After my first session or two and sabot inspections i usually give it about 50 passes if i feel it needed it. Out of all of mine only 2 have not had any polish because they were fine out of the box and i like the way they load/shoot.
I do use MX conditioner on all of them. Im still on the fence if its the best but it ranks VERY high imo. After about the 3rd shooting and cleaning sessions the difference has been very good to excellent. I mainly like it because i sometimes i forget to dry swab before popping a couple primers and ive not seen any really bad effects.
Rings and mounts
IIRC the Leos, T/Cs and Maxima are nearly identical. They might even be the same just re-branded. I use the older Durasight Steel QR rings and bases because the are very affordable. The bases seem to be just as well made as more expensive options. Ive got several sets on my Knights and they have been great. I got them for $10 directly from Durasight and they are Made in USA if that matters to you.
The new RedFields.
Ive got two of the 2x7x33s and im very happy with them. The glass is about as good as scopes in the $200-250 price range or better. They have a good amount of eye relief and are not too heavy. One of mine has survived a terrific beating from my GMB54 and many max loads that will rattle your teeth.
$30 for a complete QR set in STEEL is a STEAL IMO.

The GoldDot 250gr IMO is a great all around bullet and fairly affordable. They have also been very accurate with a variety of powder charges. Everything from "youth" loads to 110gr have shot great for me. If you plan on shooting mostly 100gr+ loads i prefer the 300gr. After seeing Ron's 200yard "catch", i really feel its a great choice for some serious knock down power.
