Re: Ladder test ???

Ladder test are mainly looking for results because of barrel harmonics and not fps. Don't get hung up because fps didn't plateau or even out over a 1.5 grain range. All fps evening out means is that you are reaching pressure limits or maximum fps for a given barrel length and powder combo.

Re: Ladder test ???

Can you get good groups at any distance with the sled? I could be that the rifle doesn't like it. Have you tried it with just prone with a bi-pod, or off good bags on the bench? If it likes the sled, I would say stock fit.

Re: Ladder test ???

No I have not tried off the sled but will this Saturday. Just got 200 pieces of new Winchester brass, whahoo! Started preping them match style.

Ordered a new Stock, a Bell and Carlson Alaskan II Rifle Stock Remington 700 BDL Long Action Magnum Barrel Channel with Full Length Aluminum Bedding System Synthetic Bell Carlson Alaskan II Rifle Stock Remington 700 BDL Long Action Mag It should be here today. I should have her bedded by Friday in time for Saturdays shoot. Yes I love my rifle,.
Have a LR shooting clinic all day Saturday and more LR testing for this rifle Sunday. I should have more information after.
Here is some info from last Saturdays LR testing. A few ladders and some 3 round groups from promising powder/bullet combinations from the tests a few weeks ago.
