Anyone else have any or wish there were different ones?

I'd love to have one of each of the SPC variants.

I think you need to post all your various caliber offerings in your NEW section!!

Ah, most wildcats are just for me, trouble comes with wildcats and customers with trouble is just that, trouble. I'll offer them as I prove the velocities, pressure and they feed perfectly.

LOL I don't think there are enough choices, we'll have to work harder.

Will the 6.5 reaper handle all the longer 6.5 bullets or is there a OAL magazine problem in the AR-10?

What about necking it down to a 6mm or would that just be to overbore and burn up the barrel in under 1K? I am just thinking it would be interesting to use some of Tubb's new 117 grain SMK with a BC of well over .636( which beats the 6.5 144gr Lapua bullet) developed for his 6DTAC round. They have that new boron coating which is suppose to be many time slicker than moly , doesn't come off or have acid prolems in the barrel. He will coat any bullets you have in batches of 1000. Apparently it doesn't just tumble on like moly.

I always liked the 7mm in the Short magnums. What are your thoughts on say a 7mm Reaper compared to the 6.5 given the bullet available from berger and the like? I always liked 7mm bullet as a whole they seem like the perfect balance in bc, weight, sd, and energy.

The Reaper was designed to handle all of the heavier 6.5s but specifically the 139 Scenar at 3200fps in the AR10 platform it will not work with 100-108 gr bullets they're too short..
I think a 6mmReaper would smoke the barrel in no time but the 7RSAUM should work well.

The 243 is bad enough about burning out the barrel, the DTAC in that should be about as fast as it gets.

I had someone call about the 25 souper(a 25-308) so in a couple of weeks I can chamber something for those who like the 25 cal.
