    BAW... good looking mould. Had not seen one before with the 'major arteries' for venting.

    Bill, that's funny right there. Shoot, slow as I am, with five breaths I might even have 'time' issues BTing Sure had plans for hyperventilation!

    No way the amount of fouling is not gonna be a problem though. Which means I'm doing something wrong -- or perhaps with the right compression that burn is cleaner and fouling reduced... because I know some are blowing without pushing sludge and making 5 and 7" groups. Always understood one of OE's claim to fame was for a clean burn. Maybe 2f is different than 1 1/2? I have zero issues (unless I just have not caught them yet) with blowing w/my 35-50 & OE 1 1/2.

    Other than wiping vs BT'ing in this instance, it was interesting to see how much compression tightened things up. More than one person told me compression needed to be .200 or better. I wasn't really looking for more velocity but guess that's my only option unless I want to really go through the wads or seat the bullet deeper.

    This whole BP path has really illustrated the whole 'variable management' thing. I'm always wanting to make all the changes I suspect all at once. Not good!
    Best Regards,
    John

    Can't think you'll see a huge velocity change John.

    I finally got a chance to shoot a bunch of 62 gr 40-65 loads that I tried with and without neck tension and varying compression levels. Tried some 1.5F Kik as well as 2F OE. The Kik was quite a bit slower than the OE. The best 2 loads were OE with .170 compression, 1 veggie wad and 1 poly wad no neck tension. The other load was OE with .001 to .002 neck tension. .110 compression and 1 poly wad.
    These loads both gave 5" vertical groups at 300yd. I wasn't getting the velocity Sgt Dog was, mine were in the 1250fps with extreme spreads in the 30fps range. The first shot from the cleaned barrels was the fastest and the highest in the groups. All groups were 10 shots the ES on the 2nd 5 shots in the strings was very consistent 10fps or less ES. I used a blow tube for all groups.
    For the follow up I'm going to try a little more compression and a little more powder and see if I can approach the optimal velocity for the boolit I'm using which is 1330 to 1340fps. Over all it was a productive shooting session and I feel like I'm getting close. In my 45-70 Pedersoli it seemed that compression in the .200 seemed to perform the best although it isn't near as picky as the 40-65.

    I had pretty frequent leading problems in all of my .45-70s. In the pistol, with heavier bullets, I got plenty in the muzzle. In the 27" Encore, the leading happened in the throat. I switched from purchased bullets at .458 to some new ones mic'd at .459-.462. My cast drop at about .461. This is with Lyman #2, fairly hard and my leading went away. With slower burning powders and duplex loads, the leading and powder fouling were literally mopped away. Even with BH209 pseudo BP loads, I had no leading.
