Two days ago I went to zero Eotech with 18.5"barrel in Mossberg 500 persuader.I bought two boxes of Maxam Brenneke Rubin Sabot.Maxam,who also operates in USA,has bought the license to Brenneke to make this 12 ga. slug in my Country.
The construction of the slug is very similar to KO sabot slug that Brenneke makes for USA market.
From the Brenneke website:
Back in 2001, Brenneke set new standards in sabot technology with the RubinSabot. now, we are introducing an even better version with more velocity and more energy. Specially tailored to take into account european hunters and their needs, it combines the advantages of a classic slug in 20 ga with the benefits of a sabot. The high velocity (+13 % at 50 m in comparison to CAMO) and very high energy (+25 % at 50m in comparison to CAMO) result in very good precision of 4 cm group with 5 shots at 50 m. The RubinSabot can be used for all types of hunting up to 80 m.
12 ga., 2 3/4 shell, 1 1/8 oz., 1520 fps
I only needed 3 shot to zero the Eotech from 30 yards shoting from knee position.After making 1 and 2 holes I adjusted the Eotech and made hole 3.(see Brenneke projectile)
Hole number 4 is after using the 24" rifled barrel with Remington Accutip sabot slug with the Eotech zeroed for 18.5" barrel.(see Remington projectile)
Very important to me:any lead fouling on barrel.
