I had to use a rubber mallet on my MDT rail. I didn’t have to beat it on but it took a couple pops with the mallet to get it on all the way.

OK I'm gonna throw myself on the chopping block here. I don't know how far off this thing allegedly is. Let's just say it's 10 light years away for the purpose of discussion. Does that mean that this actually took place 10 years ago and it's just now visible here or what? Flame away
Some people pay extra for that.
I bet they’ll be trading fur pelts
Shut up and let shit play out on its own.You do know the adhesive side goes “out”, right ?![]()

35.5 to 36.5, the GT barrels I've used have been great in that 2830 and 2870 range.Midwest powders 585.3 (RL16)ish
So for those of you who have this powder or RL16 here is some initial data.
1 round at each charge to get some data for speed/pressure.
Powder from American reloading. Bullets from them too.
MP 585.3 (RL16) 6 GT test data
107gr SMK pulled
34.5gr - 2767 FPS
35.0gr- 2791 FPS
35.5gr- 2825 FPS
36.0gr- 2862 FPS
36.5gr- 2881 FPS
37.0gr-2959 FPS
37.5gr-2977 FPS
38.0gr- 3009 FPS
I had the slightest swipe on the brass at 38.0 and the primers still looked rounded
So what speed would you pick to start with? I’m thinking 36.5 to 37.0
Bibi would have a bad day if Iran just decided to ignore the US diversion and continued to address Israel with missiles.Trump kneeled to Netanyahu.
A nice surgical strike but I'll stay with "We should have let them fight their own war."
From my Friend/Dealer.Well, since you have such an 'in'... any insight on my question about something in the range of a Viper PST II 5-25X being in the works?
My MDT rail was the same as yours. I only needed to use my “palm hammer” to slide it on.It’s gonna be a tight fit, try loosening or removing the cross retaining screws and use a mallet to tap it into place. Don’t try to drive it in from one end, look at and match the cuts in the receiver dovetail and scope rail.
To answer your question, I have had good luck with MDT CZ457 scope bases, even those I had to (lightly) tap into place with a mallet the first time.
