Harris bipod jump
Has anyone else notice a "bullet jump" while using a bipod? Ive noticed it on my .280 and my .223. My buddy doesn't seem to have any with his .22-250-with a bull barrel, both my guns have standard barrels.

assuming that it's mounted to the stock and not the barrel. You might check and make sure that the stock isn't bending up and contacting the barrelBob 0 -
Does the bullet jump or the rifle or both? If you're shooting off a table and using your bipod for a rest instead of sandbags, it will jump a little bit, but that doesn't mean it should throw your zero off. I often use a bipod instead of sandbags at the range, just because I don't have sandbags when I'm walking around in the woods. A bipod is just as solid as a stump or tree you'd use in the woods for a rest and shouldn't have any effect on the zero point. Just make sure you squeeze the trigger instead of jerk it and it shouldn't jump as much. Remember that the rifle jumps as a result of the recoil. The bullet is has already left the rifle, so it shouldn't effect the zero.I probably skipped around your question, but I'm sure I'll hear about it if I did. 0 -
My gun has a synthetic stock with a free floating barrel. Maybe not free enough, anyway, Im sighted in at 200yds off of a bag. When I shoot off of the ground with the bipod my groups are approximately 3.75in high. I guess thats not all bad though it puts me on at 400yds more or less. I've had the same luck with a .270 mauser with a free floating barrel, and a model six in .280... I've fastened the shoulder strap stud to the fore-arm and glass-beded it to strengthen the stud. Is my problem all me or what?

DaRoosta I was thinking that if he had zeroed with sandbags under the floorplate area (like I do) and than rested the forend tip on a bipod (or anything else) that he might be putting a little upward pressure on the barrel, wood is more stable in this situation and the blown foam stocks will flex a fair amount.Bob 0 -
Hunter How about setting you rifle up as to shoot and see if you can slide a dollar bill along the underside of the barrel. With the rifle weight as if you are going to shoot. No drag is OK, drag means some flex in the stock...Pat 0 -
OK! Found the problem,yes its flexing. now there is lots of roomall-the-way back to the action except fpr the first quarter inch. Should I carve or re-inforce? And my fathers .270 if I recall properly has a "pillow" rest on the end of his forearm.

Thats a choice you're going to have to make, me I would carve. As for dads rifle, thats his decision. There's a very highly rated gunsmith in Prescott, MI you might ask him for his advise.Another NE Mich. residentBob 0 -
Thanks tailgunner, I appreciate it. I've built several rifles off of czeck mousers, and have done glass bedding. This shouldn't be that hard of a fix now I know whats wrong for sure. I'll start with a barrel bedding file...go from there.
