What do the heavier pills get? 112 110 115?? Fps wise

115 DTAC will run up over 3400

 

[Taylorbok]

N570 I assume? Thats some serious long range smackem right there!

Yup. 3rd line down

 

[bsnyder]

That would be awesome with the 110gr atips

115 nose rings dtacs. Is the plan or 100 grain superdozer. They both have the same .600 g1 bc.

Ok that sold me. When I do my next build I know who to contact. Just have to pay off my last 2 builds first.

30 Sherman Mag 32" Barrel
250 A-tips
N570
76 gr- 2846 fps
77 gr- 2880 fps
78 gr- 2901 fps
79 gr- 2954 fps
80 gr- 2984 fps
81 gr- 3021 fps
82 gr- 3048 fps
83 gr- 3085 fps
84 gr- 3120 fps
85 gr- 3141 fps

Note these were all loaded at mag length (3.790 COAL) , powder started to crunch at 81gr. I never ran into excessive pressure but decided I didn't want to crush powder any harder.

Id like to see case head. Is web growing?

4 firings on this brass web on a fired piece measures .533 sized measures .532

What charge weights are those three? Theres ejector mark on one. How was spent primers? Thats higher velocities then a 40* 300 norma improved does with n570 and 230 a tips. Also more then a 30 nosler or a 30-28 nosler. Without pressure that is.

not sure which piece you see an ejector mark on? I'd have to dig primers out of the trash. (Might be able to do that) I fire formed all the brass with 76 grains. Did the ladder test and settled on 81gr for a charge. Some of those pieces may or may not have been part of the ladder test hard to say.

No worries just curious what you seen.

 

[Barehandlineman11]

hard to tell because so many lettering but looks like ejector marks. Might not be

I just went and checked that top one does have a very minor ejector mark. The second one does not. I checked 10 other cases very closely and they don't seem to. That could have been 85gr in the ladder test. Next time I'm testing I'll try and polish up some case heads real good so a guy can see for sure.

I need some of that magic speed dust!!!

 

[Idaho Trecker]

I'd say the 32" barrel might be helping just a bit

I tried to look for some spent primers but no luck. I'll post some from my next outing. They have a bit of flow but firing pin hole isn't very tight (rem 700) still have good round corners
