gbal Posted August 2, 2015 Report Share Posted August 2, 2015 Don't have the Sako loading-allowing for any velocity differences this might help: Federal 70 g Nosler Ballistic Tip BC.309: 3450 fps MV 1850 ft lbs then range/ vel/ft lb/drop /drift" (200y zero): 100 3100/1505/1/.8 200 2800/1220/0/3.4 300 2510/980/5.5/8 400 2240/780/16.5/15 5001980/610/34.6/24.8 gbal Link to comment Share on other sites More sharing options...

gbal Posted August 2, 2015 Report Share Posted August 2, 2015 Undrstood,as stated-I think the idea is-certainly for 'my' data,is that given the same bullet,the only substantial performance variable is velocity (loading will be within SAAMI/CIP too.) Different loader might just have a minor effect on accuracy/precision-as will rifle etc-because of quality control,braas etc,but these will be fairly minor,so th data refered to should be a good ball park-as good as you will likely get shrt of firing a sample in your rifle. No problem,but if you compare a couple on (nonSako) commercial loads/reload recipies,they should be close to what to expect (rilfe diffs of course). Sako used to publish general performance data-ll,drops anyhow-maybe they don't anymore.Good luck sourcing-but it'll be rifle specific in detail.Usually good stuff,and good brass. gbal Link to comment Share on other sites More sharing options...
