Just picked up a 10” 32 H&R Mag Contender bbl. and am looking for heavy load data. I plan to use it in big bore IHMSA match's.

I wonder how it is throated.Are you thinking cast or something else?

I was testing the seating depth with some cast last night, I'ts throated pretty short, anything cast with any bore riding Dia. on the nose will talk up at least 50% of the case capasity.
Looks like I go with a 30-20

Wayne, tough call with it being short throated. I would look at the dat for the 30-20 with heavies. Keep an eye on the OAL of the two.
Or should say heavy for caliber. I have found no reason to go over a 165-170. I tried subsonic and all but gave that up.

Jeff,
Thanks, to many Bbls and to few match's, I NEED to do some house cleaning, If N.O.E gets around to offering a .310/.302 138gn SP mold I'll be set for useing the 30-20 for CPT and a 165 @ 1050 fps on the rams.

If you are going to clean out that short throated 32 Mag contender barrel, please let me know by email or PM.

i have been shooting lyman 311241 150 gr. with 10 gr. of surplus 680 out of my bunny gun with real good results. I did run a throating reamer into it so it is throated for the heavy bullets. i have tried nei #72 the harris bullet for the 7.62x39 but it is really too long. i cant remember the velosity but i have shot many 1.5 to 2 inch groups at 100 yrds. I have even shot this bullet in my dan wesson 32 mag and it shot ok in it. the cases fell out so i am sure the pressure is within safe limits. Joe gifford aka argie1891
if you think you have it figured out then you just dont understand

Interesting, Where did you get the throat reamer, and did you do it yourself ? and how ?
At this point the 32 H&R is more of ” look what I did with this little round” I thought about useing it in IHMSA big bore Standing but I have used a 30-20 for that for many years.
Several years ago I shot with fellow in Fla. that had either the Saeco 301 or the RCBS 200 sil. loaded in a 10” 32 H&R.

I used a standard 30 caliber throater as the blr. is made from a take off 30/06. I agree it is kinda ( look what i did) but it is more than that as it is i fun project. i used a single shot shotgun and split the cost of the reamers with ric in yakima so the cost was very low. I am not sure what diameter blr. that TC. uses but if it is standard 30 cal you can throat it with ease. The hardest part of this project is getting the extractor made and working 100% of the time. joe gifford aka argie1891

Wayne, with the small case such as 32 h/r you need a bullet like the rcbs 165 or 180 sil. so the nose is placed in the barrel, preserving the limited powder space. Usually the increased projectile weight dictates a ''slow'' powder so as not to cause pressure trouble. In 32-20 I have used as slow as h322 and Re-7. RP

Richard,
As best I remember I marked a 32H&R case where the RCBS 165 sat in a chambered round and the remaining case capasity was 10.0 gn of 296,
I'm waiting on a 137 gn SP .314 mold from NOE and will see how that does in the 30-20 & 32 H&R.
Since the 32 H&R barrel package deal I have offered on two sights hasn't sold, I' may try to find someone that has a .30 Cal. reamer and open it up for a certain bullet..

Wayne, if you can locate the article titled ''The Little 30s'' by Ed Bulick it may be of interest. I cant find mine at the moment. Tom Acheson may have it. It was written about 1995 or 96 and published in the IHMSA paper and CBA journal. Richard

Wayne, I located the article. It was in the book with my 32-20 data. Who would have thought ? There was scant mention of the 32HR for big bore, however the load given was 10.5gr ACC1680 and a Saeco 165--I assume they meant the #311. This gave 1000fps--still a little light. The other load placed the Lyman 311335 over the same charge for 1000fps. This bullet weighs approx 200gr. I cannot verify these loads as I dont have a 32HR barrel so--you are on your own. Richard

In the early 32 Magnum days there was a lot of activity by target and silhouette shooters with heavy bullets in the 32 H&R Magnum. I was not internetting in those days but the word still got around quickly.
The 165-grain Saeco bullet was used quite a lot ahead of 10.5 grains of Accurate Arms 1680. This load generates a rough 1,000 fps from the 10” Contender barrel.
We shot a lot of 180-grain lead round nose and flat nose bullets using 6.5 grains of Accurate Arms No. 9. These loads chronographed about 1,150 fps or just a little under.
We bought some Lyman 311335 bullets ”€œ about 200-grains and shot them using the same 10.5 grain load of AA 1680. These loads touched 1,000 fps and were hard on brass. We found this load in FS No. 103.

Thanks,
I've got both the Saeco 301 & 311, I'll cast up a few and see how everything lines up, case capasity ,ect. and mainly recoil compaired to my 30-20.
