I did a lot of testing with the powders above and never got a 225 NAB close to 2600 AND under a MOA. my best 225 round was 2550fps with RL-15. .....but I'm shooting a 22" barreled H&R break action.
I haven't, but I'd love to see your results. I have tried varget, imr 8208, imr 4064, RL 15, W748, and imr 4895. RL 15 and 4064 are by far the most accurate.
I have some loaded with bl-c(2) but I haven't tried them yet.
all my hunting rifles are shooting under .5". I love shooting the whelen...
I've never used imperial. Unique works very well for me and its dirt cheap. I've loaded about 1500 rounds from this $5 tub and I cant really tell I've used any. I just touch it with my finger and spin the case between my thumb and first 2 fingers. if you can see a tiny spec of it on your finger...
I loaded 11 rounds with 215m just for ladder/velocity tests. the hodgdon site seems to think this powder can make a 200gr 35 whelen go pretty fast. I'll hit the range as soon as it quits raining.
the reason I ask is that I was using one shot when I was having horrible problems with my .270 win and hornady dies. now, it shoots better than .5" all day.
if you are using one shot for rifle cases, can you run this test again with cases resized with unique? I would be you will see a different result. .....and unique is about 100 times cheaper than one shot. one $5 tub will do a few thousand rounds.
I had similar results with runout on the hornady dies. I solved it with more case lube. those dies need a lot more lube than the other brands. a little hornady unique on the expander will help a lot.
hodgdon doesn't show primers for their online load data. that would make it at least a little easier. I have just about every primer that exists on the bench already. I have some 215m that I can use.
I picked up a bottle of BL-C2 this morning. I want to try this in my .35 whelen with 200gr hornady SP. hodgdon says the min load is 60.0gr with a max of 63.0. I usually use fed 210m primers but I've read a few posts that say mag primers are better for ball powders. I'm just wondering what you...
there isn't a "lot" of compression in this length. I don't really know any way to measure it. RL-15 seems to like compression. my shortest load picked up 40fps over this one and shot under an inch. at 3.300 it was compressed enough to make the press handle heavy when seating.
the hornady #8 manual shows 62gr as max with a 130sst and H4831sc. you have some room to grow. my 22" 270 win is shooting .4" at 3009fps with 61.3gr of H4831sc and the 130bt. I know the cartridge is capable of a lot more as my rifle shoots factory loads at 3167fps.
