Yeah I have both but use the Sigma (sans TC) for sports & such--rarely wildlife. I never carry both at the same time, though--I'm robust but there are limits ;~) Nice shots, btw!

Then there's this 1000mm
now I'm confused.

You can't carry both the SMC300F4 and Sigma APO70-200 F2.8 (plus the 2 TCs at the same time), but you are looking at the 1000mm monster?

Something is very wrong here

I'm glad to see you're leaning to the DA* 300/4. It may not have the versatility of a zoom but to me that's made up in it's close focusing abilities which may be overlooked sometimes. And it's close focusing abilities are very very good.
I have a Tamron-F 1.4x Pz-AF MC4 and it works fine on the DA* 300.
There is one thing to remember as you begin this journey. The longer the reach the rules change and everything gets very anal. It may not be bad if it takes a little while before you find a teleconverter. You mentioned 500 shots with the big zoom. There will also be a learning curve with just a 300mm. I blew more shots just yesterday, BIF shots are still very iffy for me and all this without the converter. You will have your hands full with just the 300mm in the beginning.
I hope you have a good tripod and head, if not be prepared to spend more money. There seem to be plenty of people who use these lenses handheld successfully, maybe so but I'm not one of them. I'm not trying to be a wet blanket here but just want you to be aware of what you're getting yourself into:-). When you nail a bird shot it's sweet but my "nail" rate is pretty low, lol.
Thanks for the heads-up!
And I think my tripod is good enough for this setup (Manfrotto 055XPROB + Manfrotto 488RC0 Ball Head). Though I guess it's a lot easier to use DA*300 handheld because it's 400g lighter than Sigma 100-300mm.

In fact, I have a 1000mm monster. Mostly it gets set up on my porch but I do carry it from time to time (but 25 meters from the car is pretty much the limit.) OTOH, I'm comfortable strolling about with either the 300mm or the 70-200mm--but not both simultaneously.

The TC is my only problem now. Where to get that Tamron?
Maybe here?

pentax 55-300 f4-5.8 with a tamron 1.4 tc and a sigma apo dg 170-500 f5.0-6.3

I have a pentax 55-300 f4-5.8 and tamron 1.4 tc. I also have the sigma apo dg 170-500 f5.0-6.3. Since the sigma has a 77mm lens, it has a faster shutter speed, quick auto focus, and better image quality. sigma weights 3 pounds.

My 55-300 on my K10D takes very sharp pix. I wonder if the Tamron 1.4 TC is degrading the images when you couple it with the 55-300 ?

I recently have some chances to take some birding pics with Sigma 170-500mm Apo DG, Sigma 150-500mm Hsm and Sigma Apo 300mm f2.8 with Sigma 1.4x teleconverter. In short, the 170-500mm and 150-500mm are very good in IQ and sharp even @ 500mm but you need to stop down at f8 and not wide open. The Sigma Apo 300mm f2.8 with Sigma 1.4x teleconverter is sharp even wide open. Some pics for reference and for sharing.

I have a 55-300mm and it's a very nice and handy lens but I don't think it's of sufficient quality to support a TC.

Those are very nice photos, dsport. Good lenses, to be sure--but also very well used!
