Yes, the radial will kick up dust, especially if shooting prone and also up. Yes, it makes it hard to see. Mine came on the Ultimate. BRAKES ARE LOUD.
THAT is why I highly recommend the LR Customs T-Rex brake, which is a tactical (side ported). It is an EXTREMELY affective brake and one that is going on my next rifle. Contact Levi. His brakes come with a load through funnel.
You will be very happy if you take that route. You'll be able to increase your charges without the recoil. The kids will appreciate it. Oh, the friend in that video says he can see the bullet impact with his T-Rex.
If you have the AGS system in your RUM, it
IS the Gen2 breech plug.
I shot the 325gr Fury star tip, now a 320gr, last year and they'll work to 300yds. Anything beyond and I had problems keeping a group. At 400 the target wasn't even worth review. I was sending them with 105grs by weight of BH. The 300gr SST's I sent with 112grs by weight at 2,400fps.
I have 100 of the 275's and 100 of the 300gr Fury I'll be shooting this summer.
You WILL be happy with the T-Rex brake from LR Customs.
Congratulations to the kids. Nice critters
