Chambered a 7 twist for 88 ELDM ....
I throated it for OAL of 2.385" which puts base of bearing surface at neck /shoulder junction.
After fireforming some more brass ,mainly for barrel break in i loaded some 88's over varget.... shots 57, 58 and 59 produced a ......096" ctc group.
While im pretty sure i can easily reach the next node....... this load is already at 2960 fps and should speed up with more rnds on barrel...... while this is only one 3 shot group... .096" is hard to ignore!
I will probably test more at this level then see what velocity is possible with the extra capacity of longer OAL after barrel settles down velocity wise.
