Getting started and need some advice

Good morning. New member here. I have joined a local indoor club and am looking to put my late fathers bullseye guns back into service. I come from a primarily shotgun world, so pistols are kinda new to me. I have my dad's pistol box with a model 41, high standard supermatic, model 52-2, and a Colt GCNM MK4 S70. I also have a fair amount of ammo for all as well.
I'm looking to be more of a weekly league type shooter and doubt I'd ever take it as far as I have with trapshooting(registered ATA). Something to get out weekly and socialize and build on my pistol shooting.
My question is am I going to be hurting the value of these guns shooting them on the regular. The .22s have been used most with the centerfire guns being in used very little to almost brand new in the case of the Gold Cup. I don't want to depreciate the value using them, however that's what they were made for and I take extremely good care of my guns. Dad did sell off all of his reloading gear and I'd like an opinion of what would be a decent set up for a weekly shooter. I have a progressive set up for my shotshell reloading and generally reload 8-10k shells per year.
 Thank you for any imput to help this "newbie"

Welcome to the forum from a trap shooter from back in the 60s.  Shoot those guns and enjoy them.  A Dillion 550B is what is started with and still think it is a good chiose.  Well really I started reloading with a MEC 400 but that was long ago.  Don

Sounds like a nice set of guns.  The only thing I would consider is upgrading the 45 by fitting a normal barrel and bushing set.  Maybe a Kart barrel tho the gunsmiths here might have other ideas.  The barrels in the Gold Cups just weren't set up correctly by the factory.  

As for a reloading setup, you'll need a small progressive like a Dillon 550 or Square deal in 45 and 38.  I would also get a single stage to learn on, but this can be a RCBS Partner or a simple Lee press.  If you opt for a bigger progressive like a Hornady Ammo Plan, Dillon 650, or  a RCBS Pro 5/7, you'll find a single stage is more of a requirement.

Wobbley is right on the Gold Cup NM mine had terrible groups at 50yds off a Ransom Rest.  A new NM bushing which i fit made a totally different gun out of it.  You can do one load at a time with the 550 so it is much like a single stage but with no need to change dies.  You can start at stage one and run a single load around one stage at a time or you can use it like a single stage and run all loads through one stage using a loading block just as with a single stage.  Don

Just shoot the .22's for a while in the league and enjoy sharing something that your father enjoyed doing. Leave the 38 and 45 for later if want to take it further, don't spend any money on them I bet your father knew what worked. Simply amazing how fast people will spend other peoples money here.
 Make sure the guns are secure in the box, I have inflicted more dings and dents to my guns while transiting to the range than I ever did at the range. Make sure they are properly lubed before you shoot and don't over clean them and they won't be any worse from the occasional use.

Once you shoot the league for a bit I bet there will be someone you can get ammo from or trade shot shells for. Enjoy the league.

+1 on what Robert stated above.

Enjoy what was passed to you.
I believe that that is what it was meant for.

To answer your specific questions - I don't think you will decrease the value of these guns very much by shooting them. It sound like you take good care of them so you are good on that side.  You don't want to over clean bullseye guns because they actually wear faster that way.    The process of complete disassembly is what cause the wear.  You can clean the bore if you want and keep them well oiled for best performance. I only tear mine down after several thousand rounds. 
Robert speaks the truth about transporting.  Things can get dinged around in the box so use some caution there.
On the reloading side, since you are a season reloader you could add a progressive press when you run low on the ammo you have.  I'm a Dillon 650 user but you wouldn't need that for just the two calibers.  A Dillon Square DealB would be perfect and those are pretty cheap used.  The only caveat is that they use proprietary dies but I would still go that route.
For the amount of competition you are anticipating, I wouldn't have any work done on that Colt.  Indoor leagues are typically 50ft or 75ft so your long range accuracy needs aren't there.  Even if you moved outside, there are leagues around me that still shoot 75ft so you will be fine.

Good luck and enjoy your dad's legacy.

Congratulations on picking a great sport. Very social, like shotgun sports, and everyone will be more than happy to help you. Don't worry about buying anything right now, just go shoot the league with what you have, afterwards you will know if you need to change something. Since you already reload a lot, do yourself a favor and get a Dillon 650 with a case feeder, powder check alarm, and roller handle. 
BTW, where are you located?

Greetings from the buckeye state! I really appreciate the input. Keep it coming, I enjoy everyone's opinions and experiences. I got a chance to shoot a little last evening and had a great time. A couple of the seasoned guys took the time to check out my gear and offer up some pointers which were quite helpful. A question about this Gold cup. I don't think this gun was ever shot, more likely salted away. It's 99% w/box, papers, and hang tag.This is not the gun dad used back in the day.Must have cut it loose sometime in the 90s. If I chose to shoot it, should I install a lighter recoils spring? All of my .45 ammo is handloaded 185/200 swc 3.4-4 grains of BE type stuff. If so, what would be a good weight to start? I don't think I'm going to alter these guns at the moment, as they can certainly outshoot my abilities. Although the red dot set up I shot last night was pretty slick! Lol. As for reloading, how do you guys retain your brass? I assume once it hits the floor, it belongs to the club. I will be keeping an eye out for a used Dillion ounce my stash of ammo gets depleted. 
Thanks again

Most of us use a CMM brass catcher which stands on the bench.  A bit pricey, but worth the money in saved back muscles if nothing else.

No, when your brass hits the floor it does not then belong to the club.  I'd really like to see how shotgun ranges defend that in court anyway as property transfer requires some sort of compensation.  Since non-autoloading shotguns are charged the same fees why are shells from autoloaders taken?

Re: Recoil spring-Your load is nice and light, perfect for bullseye. Use a spring so your empties eject reliably but don't fly 10 feet. A nice arch, landing about 2 feet to your right is good.

Re: Brass- Those who reload save their brass. Many mark their brass with a colored stripe with a sharpie and pick it up or you could consider a brass catcher for convenience.

Welcome!

If that Gold Cup is new in box then look for the other spring in the box. I bought several 70 series GC and they both came with 2 springs. I also have got some great results out of my factory pistols.

Welcome to the sport!!  I'm in the same place, just a few years before you..  If your shooting league your probably looking at just shooting .22..  That's where I would start.  The High Standards are a great older gun, but do have some quarks...  Read up on care and feeding of them, and the other guns also. As for value? If you like me the value is in using dads old guns!!  I shoot my early 60's High Standard every weekend, and love it!
