Anyone use Talley extended base or double extended base?

My understanding is that the extended bases bring the rings closer together. Can anyone give an approximate difference in distance between the different bases? My current setup (M70 .375H&H) is not ideal and with the standard bases puts the ring only a few mm away from the objective.

I guess this a Warne forum?!

Hahaha I guess maybe, I put Warne on the last gun I put a scope on . I'm sure Talley would've worked fine lol

I use the extended front on Model 70s in 375 and 416. Gives plenty room with most Leupolds I mount up.

channelkat I had standard Talley bases on my G33/40 7x57 and was very limited to what scope I could use so I ordered their extended rear base and was able to use the 4X Zeiss that I had intended to from the start.

I have an extended front base on my Win M70. It looks a bit odd but allows a greater range of scope mounting options.

I know this thread is almost two years old, but I was just in touch with Talley Manufacturing over this same question. They advised that the "extended" front base allows the user to move the front ring rearward by 0.25", and their "double extended" front base adds another 0.25" of rearward movement (for a total of 0.5" compared to the standard front base).

Great info.

I've used an extended Talley front base only once. It was I believe on a pre-64 model 70. My memory is foggy, but I think I used it because I was not getting correct ejection (maybe hitting QD Lever?). At any rate, it solved the predicament on the front base. I believe it moved the ring forward about 3/4" by placing the ring on a cantilever past the front ring over the barrel.
