aister Posted January 22, 2012 Report Share Posted January 22, 2012 the most accurate load i worked up for my .223 a-bolt is, rem brass, win primer, 52gr a-max over 24gr of h4895. i tried the loads for the first time over my mates chronograph today and found that the average velocity was 2825fps! does this seem a bit low?

phaedra1106 Posted January 22, 2012 Report Share Posted January 22, 2012 Looking at the Hodgdon data it reckons on 25g as a starting load which gives 3100fps so 24g looks to be a bit too low. I know someone who uses 26.5g of H4895 with the 52 Speer and A-Max and gets good results at around 3330fps. Quote Link to comment Share on other sites More sharing options...
aister Posted January 22, 2012 Author Report Share Posted January 22, 2012 my starting load was 24gr going up to 27gr in .5gr increments. 24gr gave me the best group and as i went up the accuracy went to pot. Quote Link to comment Share on other sites More sharing options...
garyb Posted January 22, 2012 Report Share Posted January 22, 2012 hodgdon mv figures are always vastly inflated in my expierence.... My 243 is 400-500 fps slower than their published data Quote Link to comment Share on other sites More sharing options...

garyb Posted January 23, 2012 Report Share Posted January 23, 2012 Here's a thread I posted on the subject last year... http://forums.pigeonwatch.co.uk/forums/index.php?/topic/169998-anyone-with-quikload/page__p__1440817__hl__quickload__fromsearch__1#entry1440817 Quote Link to comment Share on other sites More sharing options...
aister Posted January 23, 2012 Author Report Share Posted January 23, 2012 i found some 45gr speer bullets at the back of my cupboard the other night and decided to try some loads using varget to see if i could get a fast, flat round, (thought i would try it since i had my mates chrono). hodgdon states a starting load of 25 grain and a max load of 28c. i loaded 5 at 26grain and worked up in .5 grain increments to 28 grain, which filled the case to the top, (had to tap the case to get the powder out of the filler). hodgdon states a vel of 3071fps with 25 grain and 3477fps with 28 grain. heres the results i got- 26gr 7/8" @ 100 vel avg 1712 26.5 5/8 @ 100 vel avg 2923 27gr 13/8 @ 100 vel avg 1851 27.5 13/8 @ 100 vel avg 3094 28gr 1/12 @ 100 vel avg 2025 (no signs of preasure) i am quite bamboozled phaedra1106 rightly stated that 24gr on h4895 with a 52gr a-max seems a bit low. i had a look through my notes from july last year when i worked up the load i use all the time and i have writen down that 25gr and 25.5gr of h4895 was flattening the primers and 26gr and 26.5gr was flattening the primers and there was gasses leaking around the primer,there seemed to be quite a recoil with the gun so i backed it of to 24gr and had a 5 shot group at 3/8" and that is what i stuck with. i have loaded hundreds of this same load and it has been bang on since i think i am doing things right but since working with this chrono i am starting to wonder. is this just the joys of reloading or am i doing something wrong? now that i have bored the tits off you guys i look forward to some help/criticism/p**s taking or all of the afore mentioned :lol: Quote Link to comment Share on other sites More sharing options...
garyb Posted January 23, 2012 Report Share Posted January 23, 2012 My advice is not to get hung up on MV, how often are you shooting over 200 yards anyway? If you know anyone with the Quickload software, it would be worth running your load through that, as when I did it the results were VERY close to real life... Despite what figures hodgdon with their 40 inch barrel produce GB Quote Link to comment Share on other sites More sharing options...
Kes Posted January 23, 2012 Report Share Posted January 23, 2012 Changed from Hodgdon to VihtV N133 never looked back My experience as well - use 130 for 50gr and 133 for 40grain - Mv with 40's and 133 is 3600 very flat and accurate. Shot 2 foxes consecutively at 182 and 190 off sticks. By far my favourite load. Quote Link to comment Share on other sites More sharing options...
Underdog Posted January 23, 2012 Report Share Posted January 23, 2012 the most accurate load i worked up for my .223 a-bolt is, rem brass, win primer, 52gr a-max over 24gr of h4895. i tried the loads for the first time over my mates chronograph today and found that the average velocity was 2825fps! does this seem a bit low? I had a 52 grn er doing that from a 222 years ago, I was disapointed when I found out and sought more speed, daft really as the week before I shot a vixen with two shots at 388paces. With hind sight it was enough, ok more vel is ok but that bullet at that speed is still "mustard". U. Quote Link to comment Share on other sites More sharing options...
aister Posted January 23, 2012 Author Report Share Posted January 23, 2012 thanks for the replies. dont get me wrong i am still happy with my load and wont be changing it, just surprised at the low velocity. i was also surprised at the result with the 45gr speer, i didnt think that velocity could increase and decrease as the powder load increased, i always thought that more fuel meant more zoom. i will speak to my firearms dealer and see if he can get me up some vihtv to try sometime. he does have some vectan sp10 and sp7, has anyone tried vectan? just out of interest Quote Link to comment Share on other sites More sharing options...
