Is it common to have to work up a load again after replacing the factory stock. I put a Hogue overmolded stock on my rem 700 7mm 08. Before it loved 47 gr. of Big Game behind a 145 gr. Speer hot core. Now its all over the place with that load. However it shot great with 140 Nosler accubonds with the same charge. I was really hoping to stay with the speers. I just like them better.

The bedding changed so I would expect the point of impact to change and probably the the accuracy load also.

Sure, even serious tinkering of the existing stock is likely to change your "favorite" load. Back to the range young man!

The safety of the former load is not an issue here. The new stock might indeed cause a slightly different impact and possibly make a difference in the groups. If the previous stock was glass bedded to the barreled action and the barrel floated as well as the new stock there should be no differences.

Try free floating the barrel and see what happens.

Darn guns can do strange things at times.

The old stock is just the junker factory remington sps synthetic stock. No alterations were made to that stock. I appreciate all the input. I figured I would work up a load with 140 gr. Sierra boat tails and be done. They are cheaper to shoot than any nosler or the speer hot cores and you can usually make em work at good hunting velocities.
