???? for grouse or any one else who may have an answer

Grouse. Couple questions, The 458 275s have sparked my interest. Cause I shoot a 45/70 as well as ML. What effect does the brass have on rifling if any . & whats the range of velocitys tht these work. I have no interest in pushing these 2000fps. Im thinking more along the lines of 1600-1700 for ML & 45/70 Im not recoil sensitive but my ML is an X7 & my 45/70 is an NEF. Both pretty light guns, Plus here in Michigan you gotta look pretty hard for for a 200 yard shot . Im real curious about the .40 185s but Ive got 100 or so of the 200 grain SWs that work for me so far. Being able to shoot the 458 275s thru my 45/70 may be just enough exscuse for me to try 50 of them.

One thing about Lehigh you really don't need a bigger bullet. I really like the 275's and i think anyone would. 275grn is a good all around bullet. The .459's are pretty cheap right now. Maybe that's a better option to test them out.

The 185grn bullets shipped today. I should be able to shoot them this weekend. My main goal with those is to shoot out of the 50cal for the guy's who didn't want to push the 200's in the 50. I will keep you posted.

Brass should not effect the riflings because the brass is contained in the sabot... I shot them a couple of weeks ago for the first time and I really think they show a lot of promise for me as an elk bullet. I do not believe iwould have any trouble shooting them to 200 yards with a ballistic reticule. The energy and accuracy should be there.

I am guessing - your NEF is a 45-70 cartridge gun not a ML - if so you would want to get the .458's - 275's... Also lehigh makes a true 45-70 bullet with compression rings to make them accurate out of the 45-70. I shot them from a ML also - they are an an awesume bullet...

Now your question about brass on riflings makes sense - brass is a self lubricating metal, if you can call it that, so actually they should be easier on the bore than copper.

If you would like an explanation of the rings let me know I found an explanation the other day but really forgot what it said - i can find it again. These are the bullets that are being used by current CF 45-70 hunters.

Hope some of this helps....

Its my understanding that the rings reduce pressure like on a barnes XXX
