30-30 / 35 Rem and 45-70

[SJB358]

as evidenced by the same case having been fired by a friend 42 times with no indication of thinning at the web when measured with an RCBS Casemaster.

Holy cow!

Exactly.

So far, I have done really well with WW cases, 36.5gr LVR, and the 170gr Speer DC and Sierra. They run about 2250-2300 out of my little Win M94. Accuracy seems to be really good for open sights and the speed seems pretty decent. Case life seems great, no pressure signs and the the brass is on its 4th loading.

The 35 Rem is using the 200gr Rem CLRN, 45gr's LVR, WW cases, BR2 primers and a speed of about 2300. This load shoots well for me also and the bullet seems to be very well built for that speed. It is a Marlin 336CS and has a Williams peep on it as well. I will get it out this year. Hoping to see what the old Marlin does this year.

Overall, I am very impressed with the LVR powder. Really wakes up the older cartridges a bunch and meters like water. Scotty

Scotty,

If, according the rule of thumb, your .35 Rem case is exhausted by the time it's stretched enough to receive a third trimming, and with LVR it takes about 22 firings to stretch enough for a trim, I imagine you'll get about 60 rounds out of a case.

I might cut that in half just to be prudent. I don't know how many decades it will take me to cycle through my brass and fire each 30 times, but if I haven't expired myself by then, I'll decide at that time whether or not I think the cases can handle 60.

I believe LVR reaches its pressure peak outside the case, sparing the brass from the peak, which allows us tremendous velocity with low pressure--and great accuracy.

I also believe, although I have no intention of testing the hypothesis, that short of pounding in the powder with a hammer and punch, it's not possible to put enough LVR in a .35 Rem case to cause dangerous pressure in a 336 in good working order. But I'll let someone else tinker with that assumption.

Good shooting!
