35-30

[Tatume]

Hello Folks,

I’ve long been interested in the 35-30 wildcat, but have never seen any loading data for the cartridge. Do any of you know of any reliable data? If you are confident in your data and you’re willing to share, I would like to review them. I’m particularly interested in data for the RCBS 35-200-FN bullet. My motivation at this time is academic, as I haven’t yet made the decision to have my Marlin 336 rebored.

Thanks, Tom

I've read before that the internal case capacity of the 35 Rem. and the 35/30 are near identical.

If you use suggested starting loads with 35 Rem. load data and " work up " you shouldn't have a problem.

There is an abundance of 35 Rem. load data out there for you.

COTW 11th lists a load for a 208gr lead bullet / IMR-4198 / 25gr / 1895 fps. The case is only a grain or 2 smaller in capacity than a .35 Remington.

that 25 grs of 4198 load above is the same one I use in my 32 win special only with a 180 gr boolit.
it's a pretty impressive load compared to factory jaxketed rounds.
using 35 rem data and comparing it to 32 win data should make load details fairly easy.

Thank you Ben, Tex and RFR, I will look at 35 Rem data and compare them to other cartridges as you suggest. The speed from Barnes COTW is the only such estimate I've seen, but it's right in line with the 35 Rem.

Fred Smith of Bullberry Barrel Works (http://www.bullberry.com/) has a proprietary cartridge, the 35 BB, I had one in a Ruger #1, a re-chambered 357 mag. It was an impressive cartridge with both the RCBS 35 200 and the RCBS 35 250 SP. I can't seem to remember which case it was based on. It was one of the firearms I sold in the mid 90's when I got sick & didn't think I'd be doing any more shooting. Then I got better and looking into an empty safe made me even sicker. The Ruger in 35 BB is one of the ones I miss the most, been kinda lookin around for another Ruger #1 to do it again.

You might want to email them to get more info on it.

Thanks Rick, I did, and will report their response here.

Take care, Tom

The .35 Remington is a larger case than a .30-30. I'm looking at both of them right now. If you neck up the .30 to .35, the .35 Remington will still have a larger volume.

For clarification, I looked up the case capacity difference in Donnelly's manual: .35 Rem-51.76gr vs. .35/30-30 Winchester-50.06gr.

I measured water capacities of the .35 Remington and my .35/.30-30 to see how close they were.
Brass in both calibers was Winchester, the .35 Remington case was once-fired from my Marlin.

Capacity in grains of water filled to base of neck:
.35 Remington = 39 grains;
.35/.30-30 = 34 grains.

When a 200-grain bullet is seated in the .35/.30-30 case, its base is 1/3 the way up the neck, so I took another measurement, this time filling the case neck with water and carefully squeezing out the excess pressing a bullet to the crimp groove in the fired case.

That result was 37 grains, only two grains less than the .35 Remington.

I have found that using reliably pressure tested .35 Remington load data was OK as a guide as long as I stayed a grain or so below maximum loads. This has worked with complete satisfaction in practice.

201-gr. plainbase Modified Saeco #351, by http://www.hollowpointmold.com

7.2 grs. of Bullseye 1050 f.p.s. - Sd 37, necks smoky. DO NOT REDUCE
7.8 grs. of Bullseye 1250 f.p.s. - Sd 19, clean shooting hot weather load
8.4 grs. of Bullseye 1313 f.p.s. - Sd 11, Max. useable without any leading
9.0 grs. of Bullseye 1371 f.p.s. - Sd 17, Some leading when cast in 1:30 alloy. OK with COWW, but DO NOT EXCEED.


My usual deer load is a 260-grain LBT flatnosed, plainbase cast 1:30 with 16 grs. of #2400 for 1420 fps., approximating .38-55 Winchester ballistics.

A nominal caseful of 4895, 4094, Varget or RL15 also works well with a Walter's card was under the bullet base, for about 1600 fps.

Check with "badgeredd" here at Cast Boolits. He has built two .35-30's and can tell you everything you need to know about the cartridge and the guns that shoot it.

Hope this helps, :-D
