Went to the range with 405 LBT gas checked (sucker bullets) on top of some H 332. 22'' barrel Win Brass OAL 2.560 FED 215 Lee Crimp.

Temp 60
52gr 1965
53gr 1975
54gr Didn't try

Do you think I should try the 54gr load or am I pretty much at max now?
What I'm thinking about doing is dropping down to 51gr. I'm guessing that will give me about 1950

Gurn,

I'm assuming that your talking about a 45/70? I use H322 in my 1895M 450 Marlin. My 350gr Hornady load is 58.0grs, my 460gr CPB WFNGC load is 48.0grs. Both loads are very compressed yet they don't exhibit excessive pressure (primer cond., case head expansion, or extraction). Velocities are 2,050 and 1,780 fps. I've also used 322 in a 35 Rem T/C Contender Super 14. It seems that H322 likes to be loaded at top end for best accuracy. I just started to use a Lee FC die, so I'm backing off a bit and try to work up a new load. I'm hoping that I can use less powder for the same velocity with the FC die. I would like to get away from the load being so heavily compressed.

Hi Gurn-Brian Pierce loads a 415 GC RCBS bullet with 50 grains of RL-7 for 1960 fps out of the Guide Gun with 1.45 groups at 75 yards with open sights.My guess and only a guess is your approaching a max load and it's time to pick the accurate one.The gas checked 405 typically has a slightly higher velocity with less pressure than the jacketed bullets in the same category.Hodgdon list 55 grains as max with the 400 Speer at 1984 fps out of a 24 inch tube.So if you do a bunch of guessing and take 50 fps off of the 24 inch velocity you get 1934 fps out of a 22 inch barrel for the jacketed Speer.Guess-Guess and Guess and as I said your reaching a max(40,000 CUP) load and after the most accurate one up there.I think Buffalo Bores 400 grain is listed at 2,000 fps which makes your loads certainly within the limitations of your Rifle :lol: .

Best of luck and keep your test a commin.Jayco.

Yeah, but Buffalo Bore uses that worthless 405 grain Remington JSP in that load, not a "400 grain."

Ok guys thanks for the information.

I will do another round 51 52 53 54 may be a 55, depending on the crono reading of the 54. using 2000 fps as a max
I'll keep the one that shoots the best.
If anyone thinks I'm screwing up with this thinking, feel free to speak up.

Jayco, did you ever get a chance to shoot the Super Martin Bullets?
I was going to try and contact him to see if he would sell me some to.

Jackfish-I thought that BB used the 400 Speer in the beginning?I must be loosing my mind again.Isn't it interesting how he rates his bullets?405 Rem as an expander load for 1,000 lb animals and the 350 Speer is the penetrater for 2,500 lb animals?

It's all so confuseing!!! :lol:

Jayco.
