Reload data for 150 Nosler Ballistic Tip in a 308 Winchester

[Don McLachlan]

I currently am using a 125 grain NBT with 748 Winchester powder which works well on small game. I wish to try a 150 grain NBT with 748 Winchester powder for deer. I find no information on the use of 748 powder in the Nosler reloading data. On the Winchester web site they list using 48.5 grains of the 748 for their 150 grain soft point bullet with a speed of 2865fps. Would this be a safe load using the 150 NBT in a semi-automatic 308 Winchester?

hey Don, winchester 748 is a good powder but its cold /heat senative that said i use this powder my self in 308 also i''d start lower by 1.5 grains and work up, semi-autos need a medium burn powder charge to cycle their action,i''d also small base my brass 4 this rifle, no pun intended. i''ll also say it''s a dirty burning powder and in a semi-auto its imparative too keep the action clean, gases blow back and forth as the action cycles, one great powder is Varget, super clean burning, best of luck ps i shot my lifes best group with that 150 bal-tip 308 winchester this past summer 9/16ths 3 shots at 600yards...regardsjjmp :grin: :grin: :grin:

Depending on which semi auto .308 Win your talking about you'll not want to go with a powder with a slower burn rate than IMR4064. Varget might be a good choice or try H4895 also. If memory serves me right IMR 4895 was the original powder used for 147-150gr bullets in the milspec 7.62 ammo. But H4895 is one of the Extreme powders from Hodgdon's so it should be less temp sensitive.

Actually, US M80 ball ammo originally used IMR 4475 powder. This is a non-cannister grade powder, i.e., not commercially available. Its burn rate is faster than IMR 4895. Current ammo uses WC 846 powder. This is a ball type propellant, similar to BLC-2.

The only US 7.62 NATO loads with production specifications allowing the use of IMR 4895 were M118 (173 grain projectile) and M852 (168 grain Sierra). Use of 4895 was optional in M118 (with WC 846 being the alternative), and MANDATORY in M852.

I think H4895 (known in Austrialia as ADI 2206H) or a derivative thereof (AR 2206 - no US equivalent. Slightly faster than H4895) was originally used to load Australian military 7.62 ammo (144 grain ball projectile, IIRC).

I get consistent .4-.6 four shot groups in my fincky 1:12 twist shilen bbl using 49.5 gr BLC-2with cci 200, Hornady case and 150gr NBT's.. This stupid rifle of mine only shoots 46.5 BLC-2 with CCI200 and Hdy cases, 168 Hornady match bullet or Black Hills Match (which from the looks is a Hornady 168 match, 46.5 BLC-2 load!) under .5 most of the time.

Varget 42.7 and cci 200 in a hornady case with 168 match is consistent .6-.8 with Hornady 168 Match and 168 Ballistic tip.

I have had very good luck with RL15 in a variety of temps in my Kimber 308 but using 165 grain bullets. Maybe it would work for 150 grainers too? :?:

The load we now use is the M118LR in the 308 Win it consist of Reloader 15 powder and a 175 Sierra MK.....in LC Brass.

In my personal rifle I use IMR 4895 @ 43.6 with 168 MK and Fed 210M primer in WW Palma Cases.

and my hunting load Varget @ 44.2 with 180 gr Nosler AccuBond and CCI Br2 Primer in WW Cases
