You may have some difficulty finding that stuff in a store these days. I am sure you could order it from your local shop. Although, I have seen some casting equipment in Cabela's in E. Hartford. You could order it online too...
Your best bet is to order online, I haven't found any local shops with more than the very basics. www.midwayusa.com has just about everything you'll need. Prices are a little higher than other places but thet stock almost everything you'll need. www.natchezss.com Natchez Shooters Supply has a good selection with a little better pricing than Midway but not as many items. Both deliver very quickly.
Don't know if you are aware but there is a forum similar to this forum that is for casting "boolits" at http://castboolits.gunloads.com/index.php which is a great resource for beginning casters. I've been casting for 20 years or so, feel free to PM if there is anything I can help you with.
There are good buys to be had on ebay etc. where there may also be molds thrown in. I bought my Mag 20 from Highlander for $40. Best investment I have made in a while.
I buy lead from a local dealer, EVERYTHING else is online. Some of the companies i use require I.D. notary etc. Well worth it I am only loyal to the lowest price.
try XXXXXXXXX I have always got from them,started when I was in Mass,4 day delivery.may have trouble now as every manufacturer is going wide open to keep up with demand.Its fantastic the number of gun owners going into reloading.
I do know they give 30% of on Lee and discount all others.
