Ideas for MSP to mod into full power ACP

[HYspd]

the title pretty much covers it..

I want a new toy something to mod lots for pocket change and sweat equity...

rifled barrel at 700fps with 10 grain pellets (22 cal-using non-lead .177 using lead for "apples to apples") 1" at 25 yards for $100 +scope sound reasonable?

I'm not wedded to that price point, but i would need "reasons" to go higher..

I'd really have to hear some excellent things about the Benjamin MSPs before i would drop the extra coin for one..


the Air Conserving side of ACP for quicker full power follow up shots is very appealing to me...pumping 5 times is quicker than pumping 10 times...

my original thought was Crosman 2100, but my MSP experience is limited to watching that one peer in junior high that wanted you to treat him like Zeus for letting you shoot his...
