My recent experience with a 300RUM mirror's SBruce's explanation. I worked my load up just touching the lands to find max load with 200 gr accubonds and retumbo. I then started seating the bullets deeper to fine tume accuracy. It surprised me when I started to show higher pressure signs as I...

A friend of mine who is a chemist and a shooter turned me on to it about a year ago and sent me a bag of the stuff. It is sized 70bn, yes 70 seems to be what everyone is using. He procurred it from a Canadian company. ONe of the articles I read recently, maybe in a forum someone stateside is...

Your welcome. I neglected to mention the biggest reason I use HBN is I am hoping to extend barrel life as I like to shoot a couple times a week. About 350 rounds this spring. Some shooters are reporting a doubling of barrel life using HBN. I guess we will see.

Gone Ballistic, HBN= hexigonal boron nitride is a white powder similiar to graphite, extremely slippery. Not as dirty as moly. Cleaning your barrel after using it is a breeze, virtually no copper fouling. If you are interested google "HBN coating bullets" several bench rest shooters have...

Very nice, thanks for sharing. I have been looking at a .223AI build.

Regarding loose primer pockets in the 300 RUM which probably also relates to the 338 RUM. It has been my experience that you will get about 1 to 2 percent loose pockets on Nosler or Remington brass. I haven't noticed a difference in any of them. The RUM's produce a lot of pressure.

28.5 inch barrel, 91.4 gr Retumbo, 200 gr accubond HBN coated, RP Brass, .005 off the lands, Fed 215m match primers, 3144 fps, 26 fps extreme spread, .5 inch 5 shot group. I also had a very good group with the same load only .013 off the lands, my chrony quit working with this load so I don't...

Look at Nikons "Spot On" software and application for iphone. It is incredible for Mildot.

Thanks for your replys, it appears I have problems with my shooting technique and or scope.

jwp475, thanks for the reply. I am not questioning your answer just trying to figure out why my 100 yard zero changes. I shoot 3 different rifles out to six hundred yards. They all have bushnell elite 6500 scopes with the BDC reticle. They are 1) 358NM 2) 338WM and 3) 338-06. All of them show a...

Ok I read the sticky on altitude and barometric pressure. I am still confused. Here is my question. How do I calculate the change in my zero if I sight in my rifle at 1000 feet elevation with standard atmospheric conditions at 100 yards and actually test my drops on my BDC reticle then go to...

Going to build a 338-06 on a Rem 721 .270 action. Used for hunting elk in the Idaho panhandle. Looking a Bartlein 5r #3 barrel 6 grove, 23 in. Stainless Steel. Manners composite super lite stock. Talley rings/bases. I have a couple Bushnell elite 3200 3-9x40scopes I like may use one of those or...

Thanks for the replys. I am finding I am not the only one with these issues. And yes the action bases and rings were torqued to specs. Thanks again.

I have an older Vari X lll 3.5-10x40 (15 yo). I have always had it on a Rem 700 adl 30-06. Always worked fine. About 5 years ago I put it on a 338 WM worked fine for about 400 rounds. Then it started not holding 0. You would adjust it and the adjustment was not related to the number of clicks by...

A very good article. Explained a lot of things I did not understand. Thank you.
