Alright, I have some barnes 285 and 290 boat tails and haven’t been able to get them to group well. I’m using the supplied sabots and am wondering if I should try different sabots, maybe MMP black or harvester red, I’ve been tring to work up loads using n120 and R7 with not much luck and I need help. Give me some bullet sabot combos that I can work with ( N120, R7 and 2015 ) powders. I’m about to buy new bullets and don’t know what to try.

Most sabots are not designed for the boattail bullets. I think harvester has a sabot for boattail bullets, yellow I think. If you get other bullets, make sure they are the flat base.
The 300 gr. 458 remington or the hornady 300 gr. 458 bullet and a black crushed rib sabot should work fine with 63-67 gr of r-7. Also around 60 gr of n-120 seems to work well for most guns.

Do a search on "knurling".
Many, myself included, have found that Barnes bullets greatly benefit the knurling process.
Ditto the boat tail bullet problem. Somewhere around this or the old board is a post about different sabots and the proper size flat washer to use under a boat tail bullet to use flat base sabots.

I found knurling helped the 245 Spitfire more than the heavier 285 and 290. After I knurled the 285's they were hard to load in my gun. Knurling the Barnes is in the Tips and Hints section at the top of the page. Mike

Thanks gentlemen, I just ordered a box of Barnes origanal and a box of the Remington both in 300 gr .458 and some black crushed rib sabots. I shot up at least 50 rounds each of the 285's and the 290's trying to get them to group so I think it's time for a new program.
