After very dissapointing performance from a sierra 150 load last year I'm working up a speer 130 load. Can't get to Paco's loads with H322. His article about doing 2700 fps with 38.5 grains would probably blow my gun up. Speer lists a maximum load of 33 grains. I started at 32gr and got 2460 fps average. Worked my way up to 34 grains and was at 2726 and had some pretty flat and slighty cratered primers. Don't have a caliper that will measure in 10 thousands yet. Loads were very acurate at 33 and 34. It was 85 degrees at the time we were shooting. Just want to know what loads people are using with this bullet and what kind of performance you are getting. Thanks Rick P.S. sighted in my .444 and 45/70 also. Boy, I'm a little sore.

lantrad,
Paco must be nuts. 38.5 grains of H322 is way too much for my gun. I loaded up some 125 Sierra HPFP last year with 33 grains of H322. I got a very accurate load and a very sticky lever. Too Hot! Backed off to 32 grains and solved the problem. Your 130 grain speers would probably be at or near max with 32 to 33 grains of H322.

I got just over 2500 fps with Speer 130 fp's and H335, in my brother's 336. Accuracy was still very good at under 1.25" @ 100 yds., and he took a couple of good bucks at around 200 yds with them.

It's been a few years ago, but when I tried some real speed loads using the Speer 130's in my 30/30, my bullet would impact out 5" wide on the target like my barrel was whipping around or something. I haven't worked on it that much but my M336 is more accurate, using 125-130 grn bullets, at a little less than max load. The best that I found with the 125 psp, two at a time, was with around 30.0 grns RL-7. BM

Last year I aquired another .30/30 after over a decade without one. Back in late '80's I had a 336-A w/24"bbl, and used the Sierra 125hp extensively in it, finding it to be superior to the 150's and 170's on the smaller "southern" deer. Particularly the Speer, Sierra, and Nosler's.

I used 36.5gr of H322 from an early batch of mil-surp that I bought in bulk, and got 2,650- 2,700fps from . Imagine the performance on deer !!!! Pressures were warm, but not "hot". Ejection was effortless, and primers were nominal in apperance.

A friend bought some "then" current commercial H322 and found that 34.0gr was max as the 35.5gr max I suggested he consider, "locked-up" his action and required disassembly and using a rod to punch the case from the chamber. I initially attributed this to his gun being a Winchester m94 "Trapper", but soon found out differently after I bought some "New" H322 after I depleted my supply of the "MIL-SURP" H322.

Current batches of H322 are a bit "faster" burning than the original; much the same as current H4831 is a bit faster than the original mil-spec surplus powder of the late '40's thru the early '70's when the original stocks were exhausted.

I have switched over to H335 for the 125 and 130gr bullets, and was able to get 2,550fps from my 20"bbl Glenfield m30 and this is max. for my gun. I suggest you use Lyman's #48 max of 37.5gr which is claimed at 2626fps from a 24"bbl. This is where I stopped with my testing as there seemed to be no point in going further. Accuracy is acceptable; ~2.0" for 5-shots at 100yds (w/7x scope from bench).

I also found RL-15 to be very accurate and 36.0gr gave 2,450fps from my 20" bbl. -same as what Lyman got from their 24"bbl. Accuracy approached 1.0" at 100yds (1.1", with 3 in a clover-leaf, and a near by double).
I killed a 100lb pig and two whitetail does with this last season. I had very poor luck with the 130 Speer however, as it didn't seem to expand adequately on the two deer I hit, -and lost-, with it. Both were hit at 50-75yds in lung cavity with broad-side shots. I hope your results are better than mine with the Speer.

The Sierra is both more accurate and effective on game to 200lbs than the Speer in my 15+ yrs experience with the Sierra. At distances under 100yds, the 125gr Sierra from the .30/30 duplicates the performance of my custom .257 Roberts, and a friends (same one with above mentioned "Trapper") .25/06. Exactly what we set out to duplicate with the original experiments with the 125gr Sierra shortly after they came out with it.
