I have an old Bushmaster pump action paintball gun (68 cal). I bought it somewhere around 1990 or so. So its old. I just took it out of mothballs because a friends son asked me to come to his birthday party at a local paintball establishment.

Anyway, I went to Wally Mart and picked up a box of 68 cal balls and got my tanks filled. I filled my hopper with balls ready to go paint the neighborhood and when I pumped a ball into the chamber, about 5 of them went rolling right out my barrel. I had some old balls (over 10 years old) and they fit just right and snug like I remembered.

So my question... did they change something with the barrels and balls? I haven't done anything to my barrel, it shot the 100 or so old balls great. 68 cal should still be 68 cal right?

If its the Wally Mart balls... then whats my next best option to get balls? I used to order them (18 years ago when I was in highschool) but I don't have a clue where I ordered them from. Any help would be appreciated.

Closed bolt guns, such as all pumps, push the ball past the detent to be in the firing position. Only thing to fix it is having a better paint to barrel match. Poor mans option, get some clear nail polish, and on the inside of the barrel, roughly a little bit past where the ball is pushed, make a ring of nail polish, in essence making the bore of that spot just a little bit smaller. That will keep your balls from rolling out.

I was going to write up a nice thing about how it was detents till i read it was the mump marker. Now I really want to see pictures of it!

Another solution is to buy a cheap barrel kit which includes different bore sizes; your problem is why barrel kits were created in the first place. the hard part will be finding ICD threads, as they're nto made anymore. I'd check out icd-owners.com as there's usually a few of them being thrown around for under $30 for a kit.

maybe so but this bushmaster sounds anciant, if so it may be time to move on (i cant imagine finding parts for it is easy anymore) if its time to move on the OP may want to find his/her next marker now and see what threads it has, that way they can get the correct threads on a barrel kit and use the barrel addaptor for the time being, then just sell the adaptor or pitch it when the new marker arrives and you already have the barrel kit for this shiny new marker

good for you but for those of us who see that this is an inexperienced player with a pump may understand why a new marker would be a good idea

sure the bushmaster may be a good marker, but throw a inexperienced player with a pump onto todays field with semi-autos everywhere and its going to be a very frustrating day for them

yes experience can trump a low ROF but for someone who has been out of it for long enoufgh for the marker to collect dust, there is going to be some re-learning, and thats assuming the experience to deal with semi-autos while using a pump was there in the first place

Pumps can be a possibility against guys with speed markers. I recently played one game with a bunch of kids with a borrowed phantom. The owner had it with a barrel kit and the paint match ever so perfectly and that thing was just so friggin accurate, i took out 3 before i hot myself taken out, fired about 15 shots total.

You really need to take a posting break.

Hes not inexperienced, just hasnt played in a few years. He is also going to play with a friends sons birthday party. I somehow see these kids being 10 years old at a maximum. Hell do just fine with a pump.

I used to play semi, with my best gun being a spyder pilot. Yeah I sucked. About a year ago I switched to pump, was it hard playing agasint? Nope. And I was playing agasint d3 teams, not 10 year olds with rentals.

Just because nobody mentioned it yet the paintballs have gotten slightly smaller they are still .68 just a smaller .68 than they used to be.

I play pump more than anything and I have no problem playing against semis mech or electro once you get the hang of the game it doesn't matter what you use. Knowing when to shoot and when to move and not being afraid to take a chance now and then more than makes up for a rate of fire disadvantage.

i wasnt saying go out and get a new marker just for this birthday party, but rather if he is getting back into paintball it would be a good idea, ya i think he will be fine for a kids birthday party with a pump, but going as a walk on to any field today would be a different case

Thanks for the responses. When we played in highschool (early 1990's) there were 4 or 5 guys who were sporting SMG60's. I could always hold my own against them. So running an old pump isn't going to bother me. In unorganized games I carried a Nelspot 007 as a back-up. Worked out well several times. I'm looking forward to the occasion. There will be some 10-12 yr old kids but their dad's are all playing too... and they are all 30-somethings like me. thumup:

With good paint, my gun is very very accurate. We honed the barrel when I got it and that made a huge difference not only in speed, but accuracy. I have an adjustable jet to dial it up or down so I can get it right to the required safe FPS (I assume they still chrono guns for saftey) for given temperature/climate conditions. I'm sure guns nowdays have all that, but this was pretty fancy back in 1990.

I found this chart. Looks like there are differences in the sizes for a given ball maker. The Nelson paintballs may be worth trying for my guns.

So give me opinions... Who makes a top of the line semi-auto marker? And what should I expect to spend on it?

top line markers haven't dropped in price. they run a little over a thousand dollars. the best option if you want a high quality semi-auto marker is to buy one that is several years old and spend $200-$400 on it. You can even buy new midrange markers for around $350 brand new.

They'll all come with eyes that detect paint to prevent chops, electronic trigger frames that you can pull easily with one finger, and different firing modes for tourney play.

ya it really just depends on how much you want to spend, how much maintanance you are willing to do, and how old you are willing to go (gennerally the older you go the harder it is to get parts if something breaks)

for starters though look up the following markers, see what you like or dont like about them, all of them will have eyes, have electric trigger frames and you can get them all used (i believe all have the standard firing modes, nppl ramp, psp ramp and semi)

PM8
DM6 or DM7
PMR
Mini
ion XE (lower end of any of the ones mentioned but parts are everywhere)
