Thread: clarification 7mmRm + ar2217 + hornady eldx 150g

You can still use the pulled projectiles. If you are using a collet type puller just don't clamp down on them too hard.

Maybe post a picture of the .300 projectiles, Id think they would be ok and the only detriment might be slightly reduced accuracy, but without seeing the damage its hard to really say.
I would generally use such damaged projectiles for fouling shots, sighters, even the pressure test as accuracy is of no concern; and use only non-damaged ones for the serious accuracy/group testing.

perfect, what a massive help. I have a Lyman magnum bullet puller on its way.
I have made myself a little bit of a plan if you wouldnt mind looking over it quickly? Also Are these powders ok for both of these ? Or would you or somone else recommend a different powder? From what i can tell 2217 is good for 7mmRm, and ok for the 300.

And fire each round, Over the Chrono , record the speed aswell as look for pressure signs. Then once pressure signs are apparent, Drop back to the previous load.

Next step : Once I have figured out the correct pressure range for my setup eg.70g for the 150g 7mmRm, then load 5 of each of 67g, 67.5g, 68gm 68.5g, 69g, 69.5g, 70g.

Next Step : Once fired, Choose the recipe with the best grouping , eg. 68.5g , and load up 3x rounds of 68.1g, 68.3g, 68.4g, 68.5g, 68.7g, 68.8g ?

If im still not getting any good accuracy then I need to switch projectiles or powder ?
