    It should not be surprising that a steel plate can be hit at 236 yards with a 10.5.

    That's bad ass Trident.

    Is it just me or can you actually see the vapor trail or wave right before it makes contact with the plate in the 1st video? I'm watching from an iPod so maybe not.

    While the vids are cool, I'm not sure just what you are trying to illustrate. Yes SBRs can be accurate at extended ranges.

    The problem arises with the ballistic potential of the round when it reaches the target. A round from a 10.5" barrel is not going to provide the same terminal ballistic performance as an 18" barrel. Don't get me wrong I don't really want to stand in front of either.

    What I found interesting was the vapor trail on the first vid. This is something most people never get to see and the vid is a great illustration of it.

    ETA: Edge hits from centerfire rifle rounds on high quality steel WILL produce damage to the plate.

    Do you think the SBR doesn't show the vapor trail bc of the decreased velocity/energy or is it just slightly different lighting between the two vids?

    Thanks for the vid. That's the first time I've ever seen the vapor trail from that perspective. It's on Top Sniper, but this was a much better view.

    Please keep it up!

    How are you getting the long range impact shots- camera and lens. I'm looking for a T mount adaptor for my 5DmkII to my Kowa scope and then hook the 5D to a laptop soI can easily replay the video from my shooting position.

    What was that P-rail to camer mount on the MRP?

    It's nice to get people outside, actually shooting their guns, so with that in mind, please accept my thanks in providing data to the readers.

    However, long barrels are primarily to provide the projectile with sufficient velocity (really force) to do work at the ranges at which readily hitting a torso becomes less than easy. There was also a time in which we were all shooting with iron sights, and longer barrels meant longer sight radius, which meant less aiming error. It has been well known that shorter barrels are more rigid than longer, and therefore (if all other factors are the same) will be more consistent.

    I have shot 10.5 inch guns out past 500 meters on torso targets, and as long as th trigger puller did his job, the target danced. However, what that little 62 gr pill will do at that velocity is less than impressive.
    True, whoever is on the other side of that shot isn't going to be much happier, but a few hundred feet per second more can make a significant difference at those ranges and when trying to penetrate common cover.

    Nice vids, I continue to be impressed with what my 11.5's will do at 100 yards for tight groups.

    Good stuff.

    Joe R- I don't want to turn this into a debate on plate steel, but the old (I believe)Portatarget steel at BSR had no cratering on the edges. I can't recall seeing any on Action Target made with AR550. The MGM targets I've shot seem prone to it. I will see if I can get pics

    OP-- you'll find that the targets last way longer when shot with the 10.5". 18" can really chew up steel. I noticed that you're shooting them with Vmax ammo. As a hanging target it shouldn't show that much pitting at 236 yards. (hanging targets are able to spread out the impact longer than a static plate) I'd only shoot them with FMJ.
