  1. Cheeky, to your original post, I had one of the first vent-rib SLPs and it has never faltered in more than a decade of 3gun. That said, Tommy Thacker gave me some sage advice when I got it. He said: "If you want it to last, run it the way it is." No extended lifter, no hogged out loading port. For me, that meant learning a thumb/knuckle loading technique to avoid blood loss. Certainly, no load-4. Also, started shooting it with the light piston for the first thousand rounds, then moved to the heavy piston. Reliable and durable? Heck, yeah. However, I might suggest, if cost is an issue with respect to Benelli, take a look at the Franchi Affinity. Except for the recoil spring, everything else is similar. Even uses most of the same aftermarket parts.
  2. Shoot 22 precision rimfire matches with it and you will see the benefits. Some go out to 400 yards, stages are similar to PRS. Even more fun because ammo is cheap.
  3. Assuming you have a FFP scope to at least 16x, can dial your comeups, and have a good ballistic app. An accurate AR with 69SMKs will hold its own out to 850 yards IF the targets have electronic light indicators, otherwise hits can't be spotted consistently. You will have to push your ammo hard and tweak your BC beyond 600. The 69TMK is a little better bullet.
  4. Put an ARCA rail on your forend and an ARCA clamp on an Atlas for maximum versatility.
  5. I use a 2.5-10× with an offset red dot. Matches in my area mix bay and natural terrain out to 500 yards. The 10x is a definite advantage in the 100-500 yard situations. In bay shooting, I turn down to 2.5x and use it for plate rack, head shots or targets covered by no-shoots, red dot for hosing. Works.
  6. Soaking in CLR overnight would have turned that crud to mud, easily scrubbed off.
  7. My experience with pencil profile 18" is that it's whippy and using a brake with top ports made my shots string vertically. 3"× .75" @ 100 yards would be a typical group. Switched to a Miculek and easily MOA. I can't tell there's an accuracy difference between my standard profile barrels in 5.56 or Wylde chambers.
  8. That "donut of buildup" will, at some point be dislodged, and could cause a partial obstruction and baffle strike. Soaking in CLR for an hour turns this to mud and it runs off with a few blasts of brakecleaner. Instead of a pick, I've used a WaterPic to clean up the crannies.
  9. 2470 fps in 18" Stag Wylde chamber. Burns clean too. Got the load from Markco on here, IIRC.
  10. Hoser load: 19.5 grains AA2200, 55fmj. Light and flat. 1.5 moa @ 100 yards.
  11. I use a light load of 23 grains of 2460 under Hornady 55fmj. Easily sub-moa to 200 even with mixed cases. Beyond that, 24.5 grains under a 69SMK does well to 600.
  12. I've found it very easy to get an accurate load with 69 Sierra Matchkings. 8208 meters very well and you should be able to get 2750+ with anywhere from 23.6 gr and up. However, I've seen lot variations with 8208, so start low and work up. Midway, Midsouth, Grafs and Powder Valley for the match bullets.
  13. To the OP, I've used a Vortex PST SFP 2.5-10x44 with a FF3 on a 45degree mount. The FF3 comes into play up close to 40 yards. Would use 2.5x for shots to 100 and 10x for anything over that. IMO, FFP is unnecessary in 3gun and the reticle is useless in the lower range. I just make a habit of checking my magnification ring.
  14. I mounted a Burris XTR 1-4 and made a raised cheekpiece out of kydex. Could be the overtravel on the stock trigger but best group I got with 124 PD handloads was 5 shots into 2.5 inches.
  15. ECN515, to your original query, I have found LC brass varies quite significantly. Since you stipulate long range ammo, I'm assuming you're loading close to max. Given that you're using 77TMKs which are pretty long, I would suggest you sort the LC brass as your mentor taught you. I have found PMC Bronze cases to be quite consistent. It is easy to get accurate loads with 8208 but it can be quirky at max pressures. The donut you mention can be fixed by chucking a TMK into a drill, putting some grinding compound on the nose and running it into your seating stem.
  16. It's a known issue with the Geissele SD 3Gun trigger. Happens with some lowers, doesn't happen with others. Geissele will exchange the OP's with a new one, but if he puts it in the same lower, it might do the same thing. I would suggest asking Geissele to replace it with an SSA-E or an SD-E (flat trigger).
  17. I have had Larue, Rock River and Stag 18" barrels and they all shot Hornady 55fmj sub-moa but only to 200 yards. If the OP holds to his stipulation of 55gr to 500 yards then he has to use Nosler 55BTs and drive them hard. Otherwise, I don't think there's an off the shelf barrel out there that will do it. As others have mentioned, using 69s or 77s beyond 300 yards is reasonable.
  18. 55s are not built the same. I use regular 55fmj are probably to 200. 55 ballistic tips were pretty consistent for me out to 400. However, the BTs cost more than 77SMKs. So, if you already have them anyway, use them. My 77s drop 16.5 inches at 350, so if your eyes are young, hold half a plate high.
  19. Also, without breaking your cheek weld, you can actually, with your right eye, watch the shell move from the matchsaver to the chamber - not just do it by feel like the rest of us.
  20. I see advantages for you actually. You can load right handed with more dexterity. You can still use a matchsaver if you lose count now and again. And you can quickly rack with your right without moving your shooting hand.
  21. Friend of mine has done well with his Larue Stealth past few years. He pushes the 77TMKs scary hard.
  22. The one-piece tube allows more consistent POI in shooting slugs.
  23. Have never got the Hornady 68s and 75s to shoot for me, but they have their adherents. However, the 69 SMK is very easy to get shooting sub-MOA, even with a 650. AA 2460 has also been quite forgiving. Sort your brass, bevel case mouths and keep the charge weight under max (for your gun) in hot weather. 8208 is not a ball powder, but drops consistently in a progressive and is also a good powder for 69 and 77 SMKs.
  24. When I was undergoing this same decision-making process, I found that 55 Nosler BTs were quite accurate out to 400 yards. However, I could always find 69 and 77 Sierra or Nosler CC bulk or blems much cheaper than the 55 Nosler BTs. And, as others have already indicated, the heavier weight bullets make hits on the long range steel indicate better. Helps the spotter or RO.
