35 Whelen Redux

[Blammer]

if you're not pushing 2450fps with that 190gr RD and the 52gr of 4350 I will be surprised.

my 35 Whelen and 210gr RCBS 35 200 mould and 51gr of IMR4350 I get 2400 fps easy as I recall.

I SWAG'd it @ 2400 but that just sounded too fast. I had my Chrony along but didn't bother to set it up. Probably next trip. I chrono'd a few loads several months ago but the results got lost on the way to my notebook.

I'll be doing a chrono test on my 200 gr. noe boolit someday soon with 54 1/2 gr. imr4350. I was expecting about 2450 fps from that load. I may be a whole lot faster than i thought i was if you got that from 51 gr. I knew that load was rocking my shoulder a bit.
My 358009 boolit clocked 2222 fps. @ 54 gr. imr 4350 the other day but of course it's almost 90 gr. heavier.

Got talked into a range trip today in spite of the heat, needed to chrono a few loads so took the Chrony along. Interesting how velocities went up with the barrel temps but we got some good data anyway. Rotated three rifles in an attempt to let them cool but with temps just under triple digits it didn't work. Velocities were quite a bit lower than I expected, 52.5grs H4350 under the RD 359-190 only yielded an avg of 1980 fps. First three were 1959, 1954 and 1953 so i figure much of the variation was due to the heat. Eight out of ten rounds went into a nice group so the way I see it Ol' Ugly has a hunting load. Distance was 100 yds.
Scopekiller was up to her usual tricks, the holes in her target can't be called a goup but the velocities were a pretty consistent average of 2046 with an extreme spread of 31 fps. Not going to bother posting her target, not worth the bandwidth.

Not bad at all for ten shots in this heat. I did expect a bit more vel., but 2000 fps. should take care of anything on this continent. I cast some boolits today so didn't get to the range, but may get to one day this week. When i do i'll try to chrono the imr 4350 with my 200 gr. boolits and see what the difference, if any, there is between the two powders.

Congrats on a good load!

I was expecting 2300 fps but 2400 would not have suprised me. I figure 1950 or so will work just fine, have killed a few hogs and deer with this boolit at similar velocities. Ol' Ugly's going hunting again, but first I need to do a bit of casting myself. All this load testing has taken a toll on my 359-190 supply.

Well i was expecting at least 2300 fps with my 200 gr. boolit with 54 1/2 gr. of imr 4350, but this is what happened today.
5 shots @ 100 yds. 1.359"

(1) 2230 fps.
(2) 2227
(3) 2208
(4) 2245
(5) 2232
2,228 fps. avg.
That's only 6 fps. faster than the 280 gr. boolit with a half gr. more powder?
Looks like not much difference in imr and h 4350 since i have a 2" longer bbl. and was burning 2 more gr. of powder than your load.

Good shooting, nice consistency. I think my group size will decrease as temps cool but I don't think the velocity will improve. Been puzzling over the low velocity but haven't reached any conclusions other than "it is what it is". I may have another go with 4895 in a couple of months, seem to recall it was a bit faster.
Ol' Ugly stayed home today but Texassako came out, the man has some interesting guns!
