DJ, I'm not sure but I would have to think that the engineers that did the R&D on these picked a 22" barrel for more then just looks. I would think they matched the barrel length with efficiency at 8 pumps.But then again... I'm not an engineer...

I think I will slug this barrel before testing BBT slugs, I suspect a slight burr in the barrel port hole, as mine seems pellet picky, when striving for one hole 3-5 shot groups at 10m in a stinger gun rest. In theory the 362 should shoot BBT slugs well, if the barrel is anything close to a Prod barrel. I just tried chambering a BBT in mine and it's too tight.The 26" Maximus barrel does not have a choke to cut off.Maybe they could be sized down? I'm going to order a 26" .22 barrel at some point, and long term I want to take that barrel to someone that can cut off the choke, put a crown, and set it up to accept Crossman sights, LDC adapters, etc. I'm hoping with the dechoked barrel, piston, valve, and TP upgrades will make this into a competent light weight slug pumper. The original barrel will be left unmodified for pellet use. It sounds like the NOE BBT molds don't need the same kind of speeds other slugs need for accuracy.

It's the 217 Eddie.
Here's where mine is at right now, I still might put a TKO on it that I also dug up, it's one of the short ones. I was using 5 pumps.
Well, I must admit, that's the first time I've heard of diminished returns by adding an LDC.

I would think they matched the barrel length with efficiency at 8 pumps.But then again... I'm not an engineer... I'm sure cost, overall length, and performance were all reasons for the 22" barrel length choice. I'm also planning on hot rod valve and piston, so I'll see the benefits of a longer barrel either way. The fact that other users are reporting a huge volume reduction when going with even a basic LDC tells me there is going to be velocity benefit to a longer barrel. I'm sure there is a point of diminishing returns, but I plan on finding it. The 26" barrel will remain factory for a while, it will take me time to sort out machine work anyway, I have to outsource all of that.

Yes... long probe (top) compared to Backpacker .22 probe (below).Mike
