hattori.hanzo Posted September 26, 2022 Report Share Posted September 26, 2022 Hi all, I have a 27,5“ (700 mm) Heym CPQ coated barrel and would like to shoot Lapua 180 gr Scenar-L put of my 7mm/.284 Win. The barrel has 8,7“ (220 mm) of twist. I am currently using N160 and getting 2769 fps (844 m/s) wirh 52,1 grs. The powder is completely burnt in the barrel. However, I also read many posts with recommendations for N165.The powder doesn’t seem to burn completely - purely mathematically - inside my 27,5“ barrel.What are your experiences with the two powders in shorter barrels?BestUwe Quote Link to comment Share on other sites More sharing options...
swinranger Posted September 27, 2022 Report Share Posted September 27, 2022 For what it's worth, I've only ever used N165 in my .284 with very good results, but then I use a 34 inch 1-8 twist barrel for my 180 / 183 grain bullets. Quote Link to comment Share on other sites More sharing options...
hattori.hanzo Posted September 27, 2022 Author Report Share Posted September 27, 2022 Many thanks for your comment on my question. The next barrel is going to have 32+ inch. I‘ll stay with N160 somewhere near pmax. N165 will not burn 100% in my barrel mathematically. Quote Link to comment Share on other sites More sharing options...
No i deer Posted September 27, 2022 Report Share Posted September 27, 2022 I use N160 in my 26 inch bartlein.. Currently use the 180gr ELDM's. 54grs gets me 2800fps at 51f when I chronied the load.. It shoots them lovely.. I've used 180gr scenars and 180gr hybrids which also shot superbly.. Tried the hybrids on RS60 and 52grs would take them too 2880fps.. This powder is a barrel burner apparently to I never used it many times.. It was very good though.. N165 was good too but a little slower than N160 Quote Link to comment Share on other sites More sharing options...
rgt Posted October 12, 2022 Report Share Posted October 12, 2022 With the shorter barrel i would be using RS60, should get you the 284 speed which works in most which is 2840 Check ES around that speed and try get it under 15 and it should shoot great Quote Link to comment Share on other sites More sharing options...
Artiglio Posted October 12, 2022 Report Share Posted October 12, 2022 I shot a barrel with the 180 scenar l , n165 was by far the best powder and achieved. 2920 fps. So may well be worth a try. Quote Link to comment Share on other sites More sharing options...
