Let's hear you sing that Dr.Mike!
I still have a couple hundred of the first cci LR primers I bought in the mid 70's, I'm glad there isn't a price on them. I shot a few recently and they still go bang!🎆
My Tikka lite T3X has a 1:8 twist and shoots 70g RDF'S over CFE223 into bug hole groups and 63g Absolute Hammers over Vihn N550 the same, plus drops coyotes in their tracks.
I've been following your thread as I have a 300 wsm that shoots 180g Accubonds very well. Lots of good suggestions here!
I was wondering if you adjusted your seating depth with your 150g AB and how far off the lands you started? Accubonds usually like a big jump to the lands, if you have any...
I'm not sure if I ever shot any 165's in my 270wsm when I had it. I'll check my notes when I get home. It sure liked 130g Etips, which is unusual, I never could get Etips to shoot in my 25-06.
I think there are several VV powder that will work with 180g, Blkram is using N165, and VihtaVuori.com lists several including N550, N555 and N560. Anyone else try any of these?
Welcome to the forum.
I agree with the above, except when I shoot monos. In my 243 truck gun I shoot 100g PT, but for lead-free I shoot 80g Hammers. Hammer Hunters work great on both deer and coyotes.
I use RL17 in my 300wsm with 180g Accubonds and it works great. I've been looking for more RL17 for quite awhile with no luck. I've thought about trying Viht. N550 as it is working very well in a couple other calibers and about the same burn rate as 17.
I got excellent accuracy with IMR4350 in my 270wsm with 150g bullets and also with my son's 6.5 cm and 140g bullets. RL26 gave about the same accuracy with more velocity in both.
I'm good as well with my 24" regular 280 Rem.
2950 fps-160g PT over RL26
3045 fps-150g AB blems over RL26
3100+fps- 140g Hammers over IMR4350
All with excellent accuracy.
