Just for reference (confusion) last Aug ingramjets posted the below topic

Thread 'bh209 lot 39' bh209 lot 39

Consensus back then was his weight was correct

A few posters on that thread are commenting on this one

Hard to do holding the cell phone........ Lot#41

120gr VOLUME leveled converted to weight. My loading area is held at 35% humidity, 24/7/365.

That hasn't been correct, as far as 120grsV = 84grsW since lot#1.
One of Western's lot#'s had a 120grV charge that weighed 74grs IIRC. It was in the 20's.

temp was around 35 degrees, i tried to find the spent sabots but couldnt find any. had plenty of time between shots. the supplied sabots do load harder so i will try those next trip out

The fact that you can't find your sabots is not a good thing from my experience. I shoot a lot of sabot loads. I've put a good 600-700 various sabot loads thru my Accura alone. I pay attn as to where my sabots fall. I have found that when my sabots fall between 16'-19' I have the best accuracy. Most of my sabots are on the ground as if they were dropped by hand. I set my chrony at a measured 20' from my bench & muzzle. I do on occasion find a few sabots farther down my range though. When I can't find the sabots, they are staying attached to the bullet & not releasing when they should. Accuracy will never be good like that. The tan MMP sabots did exactly that out of my Accura. I had a " pattern " at 50yds not a group. Switching sabots to one my gun likes, changed that & this gun shoots almost everything I put through it in a sabot at sub moa

The only bullets that I've ever knurled up to have a tight fit needing more than 5lbs of downforce to load are the Barnes mono's. None of the reg jacketed cup & core bullets needed knurling up or a tight fit to work very well. But your gun could be totally different.

Harvester high pressure red sabots with axial ribs are a bit thicker for oversize bores. Might help you out. It did in my gun
