Dac9976 Posted October 8, 2016 Report Share Posted October 8, 2016 Hi all I've been doing some load development with the above bullets and powder. Really pleased with the accuracy but MV seems low,2450fps out of a 600mm Blaser match barrel....is this about right? Rifle is used for long range planking. Cheers Danny.

dannywayoflife Posted October 8, 2016 Report Share Posted October 8, 2016 Seems very low to me whats charge weight? I was getting about 2700 in a 24" tikka t3 varmint with 140's when I had it. (Wish I'd never sold that rifle ) Link to comment Share on other sites More sharing options...
banus02 Posted October 8, 2016 Report Share Posted October 8, 2016 good evening,i have used 48grs n165 with 140gr amax at 2640fps out of a 20 inch tikka super varmint always used magnum primers as cases were sooty with fed 210 primers worked up from 45grs.hope this helps Link to comment Share on other sites More sharing options...

dannywayoflife Posted October 9, 2016 Report Share Posted October 9, 2016 That's a very light charge Link to comment Share on other sites More sharing options...
Dac9976 Posted October 9, 2016 Author Report Share Posted October 9, 2016 Not sure I'm going to get much more in the case mate. Link to comment Share on other sites More sharing options...
Dac9976 Posted October 9, 2016 Author Report Share Posted October 9, 2016 Not sure I'm going to get much more in the case mate. That's a very light charge OK I've just had a play about, looks like I could get upto 49grs in the case. I think I've been over cautious. I do find it hard reloading for a Blaser as there's not much to look for pressure wise,no stiff bolt etc. Link to comment Share on other sites More sharing options...

meles meles Posted October 9, 2016 Report Share Posted October 9, 2016 If the load is accurate, why chase velocity ? Link to comment Share on other sites More sharing options...
Dac9976 Posted October 9, 2016 Author Report Share Posted October 9, 2016 I was thinking a bit more velocity would give me a bit more range. I'm not after a hot load, I'm after a bit more performance Link to comment Share on other sites More sharing options...

Dac9976 Posted October 9, 2016 Author Report Share Posted October 9, 2016 So are you saying stick with what I'm doing or push it a bit more and see what happens. I'm using this rifle at longer ranges so variables will be greater at longer distances won't they? Link to comment Share on other sites More sharing options...

On a side note. I'm running bing 160 prohunters at 2707 in the same rifle with same powder, no pressure signs but the shoulder push is a right slap now.

Dac9976 Posted October 30, 2016 Author Report Share Posted October 30, 2016 OK so did some more development. Blaser match barrel 6.5x55 140gr ELDs.

gbal Posted October 30, 2016 Report Share Posted October 30, 2016 There you go. Two observations: Do you think 40fps is going to make any difference terminally? And is one flier in three shots likely to be replicable? Clues to answers: No,and don't know ,but given answer to first question,why risk it? gbal Link to comment Share on other sites More sharing options...
Dac9976 Posted October 30, 2016 Author Report Share Posted October 30, 2016 Well I'm glad I've done this load development as I have now got an even better accurate load. I wasn't chasing velocity I was chasing performance. Also I wanted to know why it is quite slow and was hoping I could get some answer's after all we are all learning new stuff all the time, I like to know the reason's why. Cheers Danny.
