Thread: Model 7 7mm08 150gn eldx load development

Tested these out yesterday, seems I might of hit the nail on the head. Speed wasn't quite as high as I had thought might get and unsure if I should push on. With accuracy like this I'm finding it very hard to try go up higher.
40 grains- 2600fps. Spread of 10fps for 3rounds


40.5grains- opened right up- speed 2650fps

If .5 of a grain is enought to go from 1 hole 3 shot group to just over 1 " I would suggest it's not a very stable node or msybe your just at the very edge of it. Of course maybe you muffed the 40.5gn group ? What was the velocity spread on the 40.5gn load ?
I'd be tempted to go higher if your not pushing the limit for a hot load ?

I wondered that but the spread of 10fps for 40, 40.5 had 20fps spread, 39.5 also had 20fps and was an inch grouping Seemed to be shooting good the whole afternoon, done 12x groups of handloads all under an inch but is possible. Could try 3x at 41grains I suppose and another 3x at the 40gr to see if I fluked that group also

That was my next suggestion

Never trust one 3 shot group to confirm load development.
Also if using an optical chrono don't get hung up if the speed is different from previous day as long as the poi is the same and the spread is similar....don't ask how I know

Yea was thinking it was good but then the other 2 groups being same spread and same grouping, then this being 10fps thought might be on the money! Great thinking on the extra groups. Will see how they go and will confirm if good. With the current drought I just dont want to go shooting willy nilly was all!
