[QUOTE="green 788, post: 620877, member: 3781"] I have a 24" Douglas 8 twist... I got the 8 so I could shoot the 107 grain Matchkings... Hornady says the 9 twist will shoot their 105 AMAX's in most rifles... so with the 105's you might be able to use the Retumbo load I developed for my rifle... My rifle is a Remington 788, and the barrel is the 24" light target as I recall... it's not heavy heavy, but it's heavier than a sporter barrel... all else I did to this rifle was I bedded the action and floated the barrel... no receiver work was done at all. [IMG]http://img.photobucket.com/albums/v114/green788/1062yds.jpg[/IMG] as the target says, 48.5 grains Retumbo with 105 AMAX's... use magnum primers, they do make an ES improvement. [IMG]http://img.photobucket.com/albums/v114/green788/107SMK600yds.jpg[/IMG]With the 107 SMK's, this is a 600 yard 3 shot group (don't wear your barrel out proving groups... if the first 3 land tight, try 3 more at another distance... it'll all prove out soon enough. The 25 shot aggregate mantra must be being propagated by barrel makers). :o The Douglas barrel is a good choice, and as good as anything out there if you ask me... better than most, actually. The glitterati sometimes put Douglas down, not "fi-fi the poodle" enough for them I guess. But they work, and work well... :) And with 4831, a slower but still accurate 105 AMAX recipe... see target for load info. [IMG]http://img.photobucket.com/albums/v114/green788/105AMAXat340yards.jpg[/IMG] I get 3000 (just over) fps with the Retumbo loads, and just under 2900 fps with the 4831 load. Good luck with the new build... Dan [/QUOTE]
