200 yards. I’m thinking it’s me and my bipod not getting along. 5shots. Spikes walking on concrete when I try to load it. What says the brain trust.

??? Sorry, what is the exact question?

The question is whether shooting a bipod-equipped rifle off a concrete bench, and seeing the double grouping and shot dispersion shown could be due to the rubber feet slipping on the concrete.

Yes, actually metal spikes slipping. I usually grab a floor mat when I’m on concrete with the spikes but as usual brain damage. Checked all my screws top to bottom. It’s something I did. Just trying to decide if it’s bipod load, or the aforementioned brain.

To clarify, it’s my first day out with the A-Tip 166s. This load was .3 from my best load of the day. I’m wanting confirmation that what I’m seeing is OE and not a load issue.


On a side note, the best load was 39.8 of Varget in a 7-08. This has so far proven true in two totally different custom rifles with the 162 A-Max and now with the 166 but not yet proven out. I’m sure it’s a coincidence, but I’ve heard Garvey say the same thing about his. I don’t believe in pet loads, but this is showing up time and again.

Also, the 166 Atip is faster by 30’ than the 162 A-Max with the same load. Less bearing surface? Idk

Clamp a piece of wood or angle iron to the bench. Push your bipod into that.

39.8 gr is a common charge area to be in. But of course not a hard rule.

I've done that, and I've also used an open-cell foam pad for the bipod legs to rest on. I'm not sure any method I've tried really was better than any other. I am not a fan of using a bipod in the field anyway.

Possibly 'loading' the bipod forces fore-end to touch barrel?

Fair, but in this case it’s a manners carbon fiber. I would break it before it touched the barrel.

On the weakest stocks out there, the polar opposite happens. Load the bipod, and the forearm of the stock clears the barrel even more.
