If you want I'll send you up a MagPul CTR stock. Its short and light. I don't if it will work with a pistol. Do the pistols systems use carbine extensions if not can you get the carbine stocks to work? If it works for you its yours. My AR is in the process of getting a new barrel and a PRS stock is in its future so the CTR will be collecting dust. Nice thing about getting a suppressor in 6.8 is it will now work on your 6.5, 6mm, and 6.5 rifles as well. The Reaper would be to hot for it though. You would need a 30 cal one for it. But all the rest will work.

4227 in Hodgdon and IMR is good. IMR is a tad faster then H. I have some coming. I have a suspicion that 1680 is going to be the best of all of them. 4227 is considered very close to 1680. 1680 is very hard to find as of late. Western Powders hasn't made new lots for a while but are do to do so soon. I think I may have found some though. If anyone knows where there is some in stock I would appreciate it.

You may want to look at Norma 200 and IMR 3031 as well. With those short barrels you want to stay with faster powders for sure. Other wise its slower velocity and flame thrower city. :shock: Since use of these short weapons is under 100 yards so BC isn't going to be a concern. I would use the Sierra's 90s instead of Speer's TNTs. They achieve higher velocities then the TNTs with the same charge. I believe their construction will expand and frag more violently as well. I can also find them cheaper then even the TNT value packs. For 110 I would use v-max or Hdy 110 OTMs from a terminal performance and price stand point. I hope the SSA FMJs are 90-110 they would be my first choice for plinking followed by Rem 100 PSP.

Constructor,

Those aren't bad number to the 100 PSP as it becasue of its design is usually slower then most of the other 100s and 110s. It looks if you want the one with the best ratio on complete burn, case fill as velocity although they are all close on velocity it would seem Norma 200, Rel 7 and 4227 are all about even. The velocity diff are small enough to be masker by variance. I am surprised 4198 is so far down and 1680. Which makes me think 1680 may be very good in the longer barrels 12"-18". Its amazing x-term go in there with room left and lower pressure. But When you bump it up to 60K which puts you close to a real word 55k I bet it will look worse because of case capacity.

Could you run it again @ 65K for me?

You said long ago that when you went to 110% you started to lose vel. Was that with those specific powders or did you find it to be a general effect with most powders? I ask because I know extruded and balls tend to respond differently. Thanks

I am going to have to get back to working on getting this program for myself. My tax return might be a perfect excuse to lose a couple of bills. :roll:

famous british Grendel

Id love to know where its "fame comes from" :roll:

They have been known to grow shrooms in england :mrgreen:

You certainly get the award for one liners. Thats funny sh$t! :mrgreen: :mrgreen:

Cold,

At SHOT, I understand there wasn't an AA booth, were there any new companies fielding them in their line ups? I know Les Baer ( given their focus makes sense), and Sabre. Anyone else? Is anyone that doesn't presently field one showing they were adding them?

I would ask about the 6.8 but all major ones excluding Colt already do with Armalite adding it this year. The Grend guys had said Armalite was looking at adding 6.5s and not the 6.8 :shock: Since Armalite announced they would be adding a whole 6.8 line this year, I guess they made their choice.:lol:

The Grendel is a nice round but they made some decisions that hurt it. They may have had their reasons for taking the path they did but fact is it hurt its proliferation and improvement of the round.

With the correct 6.8 SPC barrel, that should have been used from the beginning, we can now actually reach the perfomance the SPC was suppose to reach. We have 130 @ 2575, 120 @ 2600, [email protected], [email protected], [email protected] all from a 16" barrels. Even those numbers possibly being surpassed by 100 fps with the use of 12:1 twist barrels. All of this with off the shelf powders and using mostly bullets designed specifically for the 270 win by hand loaders. It's plenty effective with factory loads but can do a lot more with proper hand loads performance and accuracy wise. This is one of the many things that makes the 6.8 so attractive.
