I’ve got 5 Spartan bipod — 2 of the old style (?300?), one of the Javelin lite, and two Pro Hunt Tac (one black, one grey). We use bipods a lot in western Canada, shooting across canyons, up/down mountains — so my thoughts may not apply. Also, since we do so much mountain/backcountry hunting, a few ounces here and there makes a huge difference in comfort.
It took me a while to get used to the “carry it on your belt” approach, but now it’s second nature (I would say, those FHF holsters are the cat’s arse).
The javelin lite does not have adjustable legs and so I found it much less useful than the ProHunt Tac. Indeed, I recently ordered new legs to change out so the Javelin lite becomes a ProHunt. (shout-out to KSL shooting supplies in Manchester — fantastic customer service)
I would say, for me, the Tac part (ratchet/snap instead of tighten-loosen slide), is worth the slight increase in weight.
We aren’t allowed to shoot off the boot so that is not an issue for me but I would imagine the Tac would work well.
I was in UK in January stalking with Paul Childerley (excellent, btw) and used his rifle, which I believe had a Harris (or Harris knock-off). I had forgotten how cumbersome the Harris bipod made the rifle feel.
My only complaint about the Spartans is that, when they changed from ?300? to ?Javelin? they changed the stock adapter so the older bipods don’t work with the new adapters.
To me, it basically comes down to cost — they are expensive but, if that is not a huge issue, they are definitely worth it, even for 5% utilization rate. Quite frankly, I would imagine that 5% of a UK stalker’s yearly shots would far outstrip the shooting of even the busiest Canadian big game hunter.
Hope that helps.
Best regards
